SubjectKernel oops in 2.4.21-pre3-ac2
From
Date
This is Red Hat 8.0 with all updates plus red carpet downlaod version of
Evolution plus 1.3b verson of Mozilla plus acroread from Acrobat5.
That's pretty much all that was running at the time. Withoiut warning,
X hung, mouse hung, keyboard hung, CTL-ALT-DEL had no effect,
CTL-ALT-BACKSPACE had no effect. However, ALT-SysRq-S worked,
ALT-SysRq-B worked.

My X server is NVidia's latest release, build 4191.

Rebooted into the same kerne so I could run ksymoops. Looked in
/var/log/messages and found two OOPses. They are decoded below. I
don't know why I got the various "cannot stat(....)" lines, nor why I
got the complaints "cannot match loaded modile raid0 to a unique module
object" (and same for ehci-hcd).

Do I need to provide some options to ksymoops? It found the correct
system map file and the correct directory for modules.

I don't absolutely know that these oopses resulted in the
X/keyboard/mouse crash. I don't *think* these oopses take place in
NVidia code but I don't know enough about reading this stack dump to be
able to tell. If it is in fact the NVidia code, someone plesae let me
know and I'll happily ask them for support.

Plesae CC me with any responses. I'll provide any additional
information on request (such as .config for kernel). I am just not
certain which additional information would be helpful.

Thank you

Eddie


ksymoops 2.4.5 on i686 2.4.21-pre3-ac2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21-pre3-ac2/ (default)
-m /boot/System.map-2.4.21-pre3-ac2 (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.
