I figured it out. ;) This small additional patch on top of mm1 is
needed to get MO write support to work.

A general update patch against 2.6.0-mm1, Andrew can you apply this
for now? Looks like there was a merge error with cdi->use_count as well
in mm1.

Pascal, if you could take care of the mode sense check for RO media (see
comment) that would be perfect.

 It seems I can write CDs on my laptop now. AFAICR I was last trying it on
test8, but it was the same: if the image is over ~400Mb, the machine
freezes hard. If it's shorter, then it's ok, but still some lock or sth
is not unlocked, as the CPU is used more and more about five secs by one
or two percent. Sooner or later it's crashed as well, but I could
restart the machine before that happened. Rebooting to 2.4.2x and
writing CDs there was working all the time.
 So I do not know if it's fixed since test8, or in 2.6.0-mm1, but I am
happy with it. Also, I have two problems with 2.6.0-mm1:
- I can not deselect CONFIG_SCSI, only module or built-in available.
  Maybe something is depend on it, but could not figure out what (no
  CONFIG_BLK_DEV_IDESCSI, nothing is selected under CONFIG_SCSI).
- I have a synaptics touchpad, which is detected correctly, but only
  works if I set psmouse_noext=1. Under vanilla 2.6.0 it still works this
  way, but with 2.6.0-mm1 it works only on the console, but not under
  XFree86. Strange, as gpm interprets the input and pipes thru gpmdata

Yes, this part of the config system is hard.  It always has been.  It's
similar to "wtf do I have to enable to make the <foo> menu appear.

I bit of grepping tells us that CONFIG_USB_STORAGE turns on CONFIG_SCSI.

 Thanks! Never throught. I could come up with this:
find . -name Kconfig| xargs grep --colour 'depends.* SCSI'
(Execute in the kernel tree, and replace SCSI with whatever you like;
may help others with similar questions).

> Peter or Dmitry may be able to tell us.
 IMHO it's either:
serio-04-synaptics-cleanup.patch
serio-06-synaptics-use-reconnect.patch
synaptics-powerpro-fix.patch
serio-pm-fix.patch
input-02-add-psmouse_proto.patch (?)
input-05-psmouse-fixes.patch
input-07-remove-synaptics-config-option.patch (maybe?)
input-08-synaptics-protocol-discovery.patch

Thus meanwhile I try to revert them. Anyway, as -mm1 is already bigger,
is it possible that you release 2.6.1 in this year with some/most of the
fixes in mm1?

 Just found out psmouse_noext is deprecated. I have specified
psmouse_proto then, but imps and exps (and bare too, but I have not
tested it, as reading the code it seems psmouse_noext falls back to
bare) are the same. On the console touchpad is working, under XFree86
4.3.0 is not. To be more specific, the buttons do work, but I can not
move the pointer at all. Well, first I thought the middle two buttons
are for scrolling, as they are placed (and IIRC, they do scroll under
m$ win), but the top button is like the left button and the bottom button
is for paste, ie middle button on three buttons mices.

May we see your dmegs, XF86Config and the parameters you are passing
to GPM please? Btw, what version of GPM are you using?

As far as reverting patches I would start with
input-08-synaptics-protocol-discovery.patch

down the files a bit, if you would like to see the whole files or other
parts, please ask - I thought it would be easier to see the relevant
lines only). gpm is configured by /etc/gpm.conf , but it should be:
gpm -m /dev/psaux -t ps2 -R raw
Also, the XFree86 Synaptics driver prints this while starting and
switching between console and XFree86:
Synaptics DeviceInit called
SynapticsCtrl called.
Synaptics DeviceOn called
Synaptics DeviceOff called
[the last two repeated more times]

> Btw, what version of GPM are you using?
 I am running Debian Sid, thus I also thought gpm is the newest; as I
do understand I should use 1.20.1, which is the latest AFAIK. Thus I was
shocked a bit on what 'dpkg -l gpm' gives:
ii  gpm            1.19.6-12.1    General Purpose Mouse Interface
More than a year old! Already filed an important bug on this. Sorry, it
seems to be the problem, or at least produces strange behavior:
I plugged in an USB mouse, which works while the touchpad still not
under XFree86 (both works at the same time under console - even if I did
not specified any additional config for gpm). The config for XFree86:
-- XF86Config-4 --
Section "InputDevice"
        Identifier      "USB Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "imps/2"
        Option          "Emulate3Buttons"       "true"
        Option          "ZAxisMapping"          "4 5"
EndSection
-- XF86Config-4 --

Made it the only one pointer input. Now, if I kill gpm with 'gpm -k',
then the touchpad begins to work! Sometimes if I release it, then the
pointer jumps a bit from where I pointed it, but that's all. I'm not
good in mice stuff, so I can't explain this. Anyway, I will try to
compile a newer gpm, change it's device, so play a bit; maybe I can come
up with something.

On the other hand, the synaptics touchpad on my laptop works under 
2.6.0-mm1 without the need to use the above parameter.  I don't get the 
jitter I reported for vanilla 2.6.0 synaptics support, but I do get an 
occasional small mouse jump.  

Other than that, 2.6.0-mm1 appears to be working well on my Presario 
12XL325 laptop.

Whew.. that wasn't easy to spot... When doing PS/2 emulation for touchpads
that use absolute events, when processing BTN_TOUCH event mousedev would
stop on the very first client. So in your normal case only GPM would see
the Synaptics but once you killed GPM XFree would be the first in line and
magically start working.

My guess you didn't see that in stock 2.6.0 because you were compiling
without Synaptics support.

I am sending 2 patches - one to remove mouse jitter with Synaptics when
it is used through mousedev (PS/2 emulation) - mousedev will use 3 point
history and average when calculating deltas, the other one is the fix for
the problem you are experiencing. They should apply to 2.6.0-mm1 and to
stock 2.6.0 with minimal jitter.

 I have applied both to 2.6.0-mm1. They are just working, no jumping
mouse pointer when I release the touchpad, and both touchpad+usb mouse
working on console and under XFree86 as well. OK, I could not really
understand how they are working, as for me it seems gpm interprets
/dev/psaux only, and get both pointing device right, still XFree86 which
reads data replicated by gpm via gpmdata can't handle the USB mouse
directly. I had to use a separate config, which reads /dev/input/mice as
well. I think it's because XFree86's synaptics driver skip events from
the USB mouse. Anyway, thanks for your help and work!

Merry Christmas!

 Update: I could trigger this bug in 2.6.0-mm1 as well with the Linux
port of Head over Heels (classic game from C64). The CPU was getting
more and more used, so the game slowed down. I could quit then from the
game and XFree86. I did an emergency sync, and it succeded. Issued halt,
but it stopped at init sending term to all processes, so I tried a hard
power off. I got an error, something about slab, maybe at line 168. It
was scrolled out too fast by the stack-trace, and at the end:
ACPI-0094: *** Error: Could not acquire interpreter mutex
Crashed there. :-(

Nah don't worry about it, Andrew and I just agreed that I'd merge the
remaining changes once 2.6.0-mm1 was up. Basically, MO needs to set
_RAM capability so we can kill the various MO checks.

Please remember that you can't send the MO drive any DVD-RAM specific
commands and expect it to work. The special-casing in the probe routine
in ide-cd is there for a reason, and I don't think calling
cdrom_dvdram_open_write would be a good idea, either. I haven't actually
looked at that routine, but if it sends anything to the drive, my MO
drive won't like it one bit. It will at best error out and then
cdrom_dvdram_open_write will error out, too, disallowing opening for
write, right?

The changes are nothing like that. Don't confuse CDC_DVD_RAM and CDC_RAM
- the latter just means that it is ok to open this media for random
writes so we don't have to check for three types of different devices.

The following patch depends on the above, and fixes the 'znetboot' and
'znetbootrd' targets so that they work again (If you would prefer things
in a different format, please let me know).  Thanks:
- Update the comments to reflect how things work with the correct
  usages now.
- Fix the znetboot / znetbootrd targets.  We now always set end-y,
  and use this to figure out what image will be tftpboot'ed.

 # Notes:
-# (1) For machine targets which produce more than one image, define
-# ZNETBOOT and ZNETBOOTRD to the image which should be available for
-# 'znetboot' and 'znetboot.initrd`
-# (2) Also, for machine targets which just need to remove the ELF header,
-# define END to be the machine name you want in the image.
-# (3) For machine targets which use the mktree program, define END to be
-# the machine name you want in the image, and you can optionally set
-# ENTRYPOINT which the image should be loaded at.  The optimal setting
-# for ENTRYPOINT is the link address.
+# (1) For machines that do not want to use the ELF image directly (including
+# stripping just the ELF header off), they must set the variables
+# zimage-$(CONFIG_MACHINE) and zimagerd-$(CONFIG_MACHINE) to the target
+# that produces the desired image and they must set end-$(CONFIG_MACHINE)
+# to what will be suffixed to the image filename.
+# (2) Regardless of (1), to have the resulting image be something other
+# than 'zImage.elf', set end-$(CONFIG_MACHINE) to be the suffix used for
+# the zImage, znetboot, and znetbootrd targets.
+# (3) For machine targets which use the mktree program, you can optionally
+# set entrypoint-$(CONFIG_MACHINE) to the location which the image should be

The following patch depends on the above, and fixes the 'znetboot' and
'znetbootrd' targets so that they work again (If you would prefer things
in a different format, please let me know).  Thanks:
- Update the comments to reflect how things work with the correct
  usages now.
- Fix the znetboot / znetbootrd targets.  We now always set end-y,
  and use this to figure out what image will be tftpboot'ed.

Take a look at /sys/block/ and you'll see - when we register disks, we mangle
the disk names that contain slashes (e.g. cciss/c0d0) replacing them with '!'
in corresponding sysfs names.  So name_to_dev_t() should mangle the name in
the same way before looking for it in /sys/block.

ptecache refresh. Includes the shrink_slab() and smp_local_irq_*
suggestions as well as a fix for IPI recursion found while running
hackbench on -wli, moving the "don't shrink lowmem slabs if gfp_mask
wants highmem" logic into the shrinkers themselves, and converting
shrink_pagetable_cache() to use on_each_cpu().

How's this look?

ptecache refresh. Includes the shrink_slab() and smp_local_irq_*
suggestions as well as a fix for IPI recursion found while running
hackbench on -wli, moving the "don't shrink lowmem slabs if gfp_mask
wants highmem" logic into the shrinkers themselves, and converting
shrink_pagetable_cache() to use on_each_cpu().

How's this look?

This tries to adjust the reclaim logic so it returns status like other
shrinkers attached both incrementally and as a whole-hog replacement.

BTW
                delta = scanned * shrinker->seeks;
                delta *= (*shrinker->shrinker)(0, gfp_mask);
                do_div(delta, pages + 1);
                shrinker->nr += delta;
                if (shrinker->nr > SHRINK_BATCH) {
                        long nr_to_scan = shrinker->nr;

more aggressively reclaims slabs requiring _more_ seeks to refill.

I don't have anything in -mm1, but heres a report, up about 23 hrs 
now.

Everything seems to be working fine, and one proggy I couldn't run 
before, now does, epsons iscan-1.5.2 front end for sane driven 
scanners now works.  The major thing I see in the logs is audio 
related, and has been carrying on since last summer.

I think that each of those is related to the little two tone noise I 
play when there is new incoming mail.  There's a couple of other 
non-show stoppers but thats the major log clutterer.  The only alsa 
is whats in the kernel, and with a couple of very minor exceptions, 
it all works.  No Ooops, lockups or anything like that.  All pretty 
smooth and interactive using anticipatory at the moment.

Merry Christmas Andrew!

I don't have anything in -mm1, but heres a report, up about 23 hrs 
now.

Everything seems to be working fine, and one proggy I couldn't run 
before, now does, epsons iscan-1.5.2 front end for sane driven 
scanners now works.  The major thing I see in the logs is audio 
related, and has been carrying on since last summer.

I think that each of those is related to the little two tone noise I 
play when there is new incoming mail.  There's a couple of other 
non-show stoppers but thats the major log clutterer.  The only alsa 
is whats in the kernel, and with a couple of very minor exceptions, 
it all works.  No Ooops, lockups or anything like that.  All pretty 
smooth and interactive using anticipatory at the moment.

Merry Christmas Andrew!

BTW, could you please drop Al's RD* patches?  They change the entry points
for block drivers and thus create some hassle for people hacking on out
of tree block drivers, and obviously can't go into mainline as is.

Have you discussed this with him?  I was actually hoping to get those patches
merged up soon.

A while ago he said he's gonna redo those parts that don't change the
API for 2.6 and will postpone the rest to 2.7.
