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.
