Hello to all,

I was victim of the same problem on my newly acquired AMD 64 dual core.  I'm
using SuSE 10.  The kernel was stable when I installed it.  Suddenly, after a
kernel update from SuSE using Yast, me system crashed everyday, sometimes even
several times a day.  Nothing was found in the logs.

This usually happened like this.

After some minutes or hours, a hard disk switched off, then the hard disk LED
switched on and remained always on.  By hearing the fans running at maximal
speed, I guess that this would trigger an infinite loop.  Everything was frozen
and only a hardware reboot worked.

I thought logically that this could come from a nVidia driver bug.  I simply
started the system without X-Window, but it crashed also.

I also removed acpi, apm, microcode, mce, anything that I could imagine.  I
continued to crash daily.

I then suspected an unfinished/beta/experimental driver.  So I recompiled the
kernel to remove unnecessary code.  I recompiled it 20 times each time removing
unnecessary drivers or features in a hope to be able to know which part fails an
d report it.  I noticed that the kernel was faster and smaller, but this didn't
fix anything.  It continued to crash daily or even several times a day.

Since the xfs filesystem doesn't compile cleanly and the system freezes usually
involved a hard disk switching off and remaining blocked, I thought xfs could
corrupt kernel memory.  So I converted all my partitions to reiserfs and finally
removed xfs from the kernel.  It continued to crash.  (By the way, it's not easy
to make reliable backups when the kernel crashes randomly...  I had to use find
and cmp to make sure all files were backed up and that they were really identical)

Finally, I decided to update my kernel to the latest stable version, although
it's apparently not supported by SuSE.  I installed and compiled the version
2.6.15.6 using my old configuration and it works perfectly now...

So to sum up:
A bug has been introduced with the kernel provided in the latest SuSE 10
security update and has been fixed in 2.6.15.6.
