Ivo sent a test patch for this and I tested it., but without success. I reported my findings but 
didn't get a reply. See http://marc.info/?l=linux-wireless&m=124940189007154&w=4.

I suspect the failure is due to the same PS hardware probelms that were at the route of my original 
report.. Unless one of the wireless folks say otherwise, I think we should close this on the basis 
of busted hardware. I'm happy to simply eject the card and re-insert it now that I have some udev 
scripts to tear down the wireless configuration on the ejection and set it uop again when the card 
is re-inserted.

Thanks

Chris

Yes, it is still doing it to rc5 but only on the first invocation after the 
bootup.  Strangely, it apparently has no other effect, either on the machine, 
or how amanda itself works.

Re: [Bug #13935] 2.6.31-rcX breaks Apple MightyMouse (Bluetooth version)

[Jan Scholz]

Hi,

I can confirm the reported bug, but for me reverting fa047e4f6fa63a6 is
not sufficient. I have to remove the device id of the mighty mouse from
the hid_blacklist list in drivers/hid/hid-core.c as well, see the patch below.

Concerning the need for the quirks: I think there might be some
dependence on the version of X that is used. If I recall correctly, with
xorg-server-1.3 the quirk "APPLE_INVERT_HWHEEL" was necessary, but this
changed when I switched to xorg-server-1.5.3, where now horizontal
scrolling moves in directions you'd expect from vertical scrolling.
...but I wouldn't bet on my memory regarding things with xorg-server-1.3
since it's been quite some time ago and I never really liked the
horizontal scrolling anyway.

Cheers,
Jan

we remove Apple MightyMouse (bluetooth version) from the list of

Re: [Bug #13935] 2.6.31-rcX breaks Apple MightyMouse (Bluetooth version)

[Jan Scholz]

Hi,

now that the patch "HID: completely remove apple mightymouse from
blacklist" is merged upstream as
"42960a13001aa6df52ca9952ce996f94a744ea65" I think it should be merged
in the v2.6.31-stable series as well.

Best regards,
   Jan

Agreed. As it didn't have "Cc: stable@kernel.org" in the changelog, it 
will not be picked up automagically. 

Will do.

Yes, this bug is still valid.

our way through the changes that took place since 2.6.30 to find the
commit that introduced this regression. Please stay tuned.

hm, the only outright Geode related commit was:

 d6c585a: x86: geode: Mark mfgpt irq IRQF_TIMER to prevent resume failure

the jpg at:

  http://launchpadlibrarian.net/28892781/00002.jpg

is very out of focus - but what i could decypher suggests a 
pagefault crash in the VFS code, in generic_delete_inode().

Which could be a VFS bug, or a filesystem bug, or some unrelated 
memory corruption hitting the inode data structure.

There's a few more JPEG images below that have a slightly sharper image.

It could indeed be many things.

I've been trying to boot this into a larger framebuffer to be able to
fit more data into my snapshots, but it appears that vga=795 doesn't
work anymore. Have we reverted to Hex values again or is this just an
issue of some kernel module missing from initrd?

This one might be a bit better:

Never mind. Seems that vesafb was blacklisted. Works now. See the

Hmm.  This looks like a sysfs oops to my untrained eye.

The bisect I did with Leann Ogasawara has narrowed the kernel panic
down to the following:

commit f19d4a8fa6f9b6ccf54df0971c97ffcaa390b7b0
Author: Al Viro <viro-RmSDqhL/yNMiFSDQTTA3OLVCufUGDwFn@public.gmane.org>
Date: Mon Jun 8 19:50:45 2009 -0400

    add caching of ACLs in struct inode

    No helpers, no conversions yet.

Weird. If the functions do what their name suggests, i.e. if 
inode_init_always() is an always called constructor and if 
destroy_inode() is an unconditional destructor then this patch 
should have no functional effect on the VFS side.

It increases the size of struct inode, so if you have some old 
module (built to an older version of fs.h) still around it might 
corrupt your inode data structure.

Or the size change might trigger some dormant bug. It might move a 
critical inode right into the path of a pre-existing (but not 
visibly crash-triggering) data corruption.

The possibilities on the 'weird bug' front are endless - the 
crash/oops itself should be turned into text, posted here and 
analyzed.

Btw., before you invest any time into the 'weird crash' theory, i'd 
suggest to double check the bisection result:

  f19d4a8fa6f9b6ccf54df0971c97ffcaa390b7b0    crashes
  f19d4a8fa6f9b6ccf54df0971c97ffcaa390b7b0~1  boots fine

You can save yourself from a lot of head scratching that way - the 
bisection result looks weird. (albeit plausible - a VFS crash points 
to a VFS commit.)

_Maybe_ the bisection is just off a little bit (there was a 
bisection mistake in the last few steps), and the real buggy commit 
is one of the nearby ones:

We double checked again last week with fresh builds and validated that
the above result is correct.

What puzzles us is the start of the crash:


BUG: unable to handle kernel paging request at ffffb4ff
IP: [<c01f716b>] __destroy_inode+0x4b/0x80
*pde = 00810067 *pte = 00000000

Any ideas?

If you mean something else than the large-size snapshot of the whole
panic output that was linked earlier in this thread, I'd appreciate
instructions on how to turn that crash into text.

it's still a JPG - posting the transcribed oops in email text would 
certainly help more folks looking over it.

I welcome suggestions for proper OCR software that can extract the
text displayed therein. Manually transcribing it is too error-prone to
even try.

Well, there are less risks of errors retyping by hand than passing via
an OCR. At least *you* know that everything you see are hex numbers, the
OCR does not. Eventhough it's quite annoying to do that by hand, it
generally takes less than 5 minutes to retype an oops, which is not that
much. Of course, the serial cable to another machine to get a panic dump
is the easiest solution ;-)

That would be assuming that a serial console is available.  This is
not the case here. No legacy port whatsoever.

Yes, it still should be listed.  The first patch didn't quite fix it.
A second one probably does.

This one sounds like an IRQ routing error, so probably ACPI, but we've
been totally unsuccessful at getting any further information out of the
submitter.  Use your own time judgement on this, but if he hasn't been
responding to you either for 36 days, I'd suggest closing this as
unresponsive.

Now I'm not sure if it's a regression, because it happens not every
boot. Maybe I just noticed it after 2.6.30

jiri, I found the place via extra printk messages added to the i8042.c

in function i8042_check_aux(), when touchpad detecting fail, it fall
into following error path:

 if (wait_for_completion_timeout(&i8042_aux_irq_delivered,
                                        msecs_to_jiffies(250)) == 0) { [snip] }

so maybe the timeout value need to be increased? I try redo the
i8042_setup_aux after it fails, it fixes the problem indeed, which one
is the proper fix do you think? If it's the right fix I can post the
patch.
