Linux 2.5.5-dj2

Linux 2.5.5-dj2

[Dave Jones]

Right up to date with Marcelo & Linus, and clear inbound patch queue.
Despite the growing size, resync with Linus is still in progress,
and some of the bigger bits have now either shown up in pre1, or
are queued to go his way real soon.

Patch against 2.5.5 vanilla is available from:
ftp://ftp.kernel.org/pub/linux/kernel/people/davej/patches/2.5/

By popular request, the curious can now find most of what
was merged in each release at http://www.codemonkey.org.uk/patches/merged/

Thanks for your excellent work.

There is a slight problem with your -dj2 patch with following chunk:

diff -urN --exclude-from=/home/davej/.exclude

make distclean removes ../include/linux/version.h and thus your patch

 Yup. All went well until ALSA arrived with its own version.h
 Before then, I had version.h in my diff exclusion list, and everything
 'just worked'. Oh well.. I'll add some more magic to autohch.pl[*]

Why not include it into /home/davej/.exclude?

Regarding ALSA and showing up with their own ``version.h''; what about 
the others?

o ../arch/i386/math-emu/version.h
o ../include/pcmcia/version.h
o ../include/sound/version.h

 Possibly the easier way, I removed it before when ALSA was new
 so that its version.h showed up in the patch. (It wouldnt compile
 without it in 2.4.4-dj)

 Since I rediffed against 2.5.5, this isn't a problem.

This should be the last time I bother you today. I have some fixes for 
your 2.5.5-dj2 tree. Please consider applying.

compile-2.5.5-dj2.diff:
   o include missing <linux/interrupt.h>
   o spelling corrections
   o fix compile warnings
   o NOTE: rtc_timer.c has lots of useless #ifdef's, why can't we not
     just get rid of those? I talk about the USE_TASKLET. Or does the
     ALSA group plan to use something else then tasklets?

compile_warn_alsa.diff:
   o fix compile warnings

compile_warn_irda.diff:
   o fix compile warnings

compile_warn_vm.diff
   o fix compile warnings

There are still tons of compile warnings. If you're interested I can 
email them to you or put them in the web somewhere. Just in case you're 
getting bored ;)

Roberto Nibali, ratz

Linux 2.5.5-dj2 oops

[Ben Clifford]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


Towards the end of my boot script, I get a sequence of oopses.

However, after all this has happened, it looks like everything that should
be running is running.

They are described in the log as:
Feb 27 07:52:25 barbarella kernel: Process mingetty (pid: 1605,
threadinfo=cc3da000 task=cc15e780)

Feb 27 07:52:25 barbarella kernel: Process mingetty (pid: 1613,
threadinfo=cc11e000 task=cc120220)

However, the mingettys get restarted and work.

Interestingly, there is one at 1604, which was means, that the first one
is starting up without problem.

The remaining mingetty/login processes are numbered:
 1604 vc/1     S      0:00 /sbin/mingetty tty1
 1633 vc/2     S      0:00 login -- root

 1636 vc/5     S      0:00 login -- benc
 1637 vc/6     S      0:00 /sbin/mingetty tty6

I also get a similar OOPs when I try to run X.

 Yup, something not quite right with the last set of James' console
 changes by the looks. I already bounced him a copy of a similar oops.

 For now, you could try backing out the console-preempt.diff patch
 from http://www.codemonkey.org.uk/patches/merged/2.5.5/dj2/

Ah the joy of incremental changes. You always miss something. This is the
next set of patches. I have it running on my current system and I looked
for Oops but didn't see any. Let me know if this doesn't work. Apply the
below patch.

Re: Linux 2.5.5-dj2

[Wayne Whitney]

Hello,

I need to use the patch below to get isofs.o to compile properly when
I don't have CONFIG_ZISOFS set.  Without this patch neither branch was
being executed in that case.

Cheers,
Wayne

Re: Linux 2.5.5-dj2 oops

[James Simmons]

Okay folks. Here is another patch to fix the oops. It is against a
2.5.5-dj2 tree. I have tested against vgacon and fbcon. Note it still 
is incomplete since a few fbdev drivers break. If they where ported over
to the new api this wouldn't be a issue.

ksymoops 2.4.1 on i686 2.5.5-dj2.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.5.5-dj2/ (default)
     -m /boot/System.map-2.5.5-dj2 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
