I'm getting strange Oopses with 2.2.17 on an AMD Athlon 1.2 GHz machine.
They all happen in about the same place in free_wait() called by
do_select(). I don't see a special pattern when I look at the failing
addresses, but then, I'm not a kernel expert...
The strange thing is that exactly this kernel ran fine for months on a
Pentium II/300 machine. I then copied the whole disk from the old to the
new machine and started getting the Oopses (every few days). Differences
between both machines: CPUs/motherboards of course, 512MB RAM instead of
256MB, SCSI instead of IDE disk.
I first suspected memory or power supply problems, but memtest86 ran fine
for 2 days. Also, in those cases, I would expect random crashes in
different places, not always in do_select().
Any hints what I could try next? Hardware/software problem? More
information required? I could probably dig out a few more of those Oopses
from backup, if that helps. Here are the ones I currently have:
---------------------
ksymoops 2.3.4 on i686 2.2.17. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.2.17/ (default)
-m /boot/System.map-2.2.17 (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.

BTW, I didn't mention it explicitly, but this kernel is *not*
Athlon-optimized (since I used it for several months on a P II and IIRC,
2.2.17 didn't offer Athlon-optimizaations anyway). It was compiled with gcc
2.95.2.
The motherboard is an Asus A7V133 with the KT133A chipset which probably
has the UDMA bug, but this shouldn't affect me since I'm only using SCSI on
the Athlon machine.
