Do you think you can run the oops through ksymoops? The current one
doesn't really make much sense to me... The code section of it did not
disassemble into anything that seemed reasonable...
I can repro this Oops just by a simple "modprobe snd-au8830" so it's an
easy problem to test.
Hmm. /proc/ksyms doesn't exist on this box and /proc/kallsyms isn't
accepted by ksymoops. Here's the output regardless. This one is the most
recent repro (but it looks pretty much identical).
address@hidden root]# ksymoops < snd-au8830-oops2.txt
ksymoops 2.4.9 on x86_64 2.6.8.1-12.5mdk. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.8.1-12.5mdk/ (default)
-m /boot/System.map-2.6.8.1-12.5mdk (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.
Error (regular_file): read_ksyms stat /proc/ksyms failed
/usr/bin/ksymoops.real: No such file or directory
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
