Hi folks.
With recent kernels, I am experiencing here and there a few
Oopses. For the last one, that happened last night, the details were
still on screen so I took the time to write them down (so I don't
guarantee 100% accuracy). Here is the result of ksymoops:
--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--
ksymoops 0.7c on i686 2.3.47. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.3.47/ (default)
-m /usr/src/linux/System.map (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.

Aiee, killing interrupt handler
Kernel panic: attempted to kill the idle task!
8 warnings issued. Results may not be reliable.
--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--
This was obtained on a 500MHz athlon, running a very personal
distribution that finds its roots in a remote Debian distro.
Note 1: one line was on screen before the oops itself:
mapaddr 0x94c681d4 not valid at usb-ohci.c:1188!
Could this point to USB? I compiled USB support but I have no usb
peripheral. I want to be ready ;-)
Note 2: while I am not 100% certain about the numbers, I am sure that
ffff0000 and ffff0fff were included in the call trace. What that
means, I don't know.
I can provide more info if needed. But I will only be back home late
this evening.
Hope this helps.
Carlo
