Bug#478166: linux-image-2.6.24-1-686: airo hang when loading because of aes

Please revise your theory based on this new discovery :) As the subject says, this bug was found in 2.6.24. Sorry I forgot to check the current version; I generally would do that.

Bug#524571: Still a problem after upgrade (me too) but I add logs!!!!
Hi, after some trouble with serial cables, configuration, whatever I configured a serial link to have a console. Two weeks ago I upgraded my server with linux-2.6_2.6.26-15lenny2. I have tested this version and still crash (log attached). On May 28th a new version of the kernel was updated on security (lenny3), but I have not tested yet. This version has a new patch for xen, but I don't know if this patch is for the bug or not [1]. The crash occurs as always in my case at 6:24, when cron do some job. Today I will update to test.

I try these options in /etc/modprobe.d/sound.conf options snd-hda-intel model=dell-m4-1 or options snd-hda-intel model=dell-m25 or options snd-hda-intel model=dell-ref one by one, I put it in the file and restart my system. This dont fix my sound problem. My computer is a Dell E6400. I dont know why I put these options (dell-m4-1 or dell-m25 or ref) but these is the references that I found in the net.

This means that future versions of X (starting with xorg-server 1.5) are not going to work on these architectures unless this is fixed.

Bug#521646: linux-kbuild-2.6: Not possible to rebuild debian/control
Hi, it would be very nice to get some feedback from the maintainers here. The problem seems very weird to me because the package builds as long as I do not change the changelog which means I cannot sign the package finally when I rebuild it. I have not checked more into details yet, but I presume that the control-file or some other file of the debian build files is not regenerated properly after changing the changelog. Also, I think it's quite unlucky that one of the scripts (gencontrol.py) depends specifically on python 2.4. In any case this bug should be fixed soon, I cannot fully backport any debian kernels to Lenny at the moment without problems. Since linux-headers package depends on kbuild, I can never install them. Btw: The bug seems to be similar to 475108. Is it the same ? The original poster suggested something with __init__.py however.

Bug#517449: linux-image-2.6.26-1-amd64: SCHED_IDLE issues (tasks blocked for more than 120 seconds)
You found some scheduling changes made post-2.6.28 which seemed to deal
with this bug. However, that cannot be the full story because they are
modifying code which was added after 2.6.26.
The attached patch combines a bug fix made between 2.6.26 and .28 with
most of the changes you identified. Based on my reading of commit
messages and discussion, I think this makes a coherent set of changes.
However there have been many other changes to the scheduler in this time
and I cannot say for sure whether any of those are also required as I do
not have any great knowledge of it.
Please try rebuilding the lenny kernel (linux-source-2.6.26) with this
patch applied and report whether it fixes the bug for you.
Ben.
