| |
I received the following oops while running the Cerberus stress test on 2.4.21-pre3-ac3. The hardware is an ASUS A7N8X single AMD Athlon XP motherboard with the Nvidia nforce2 chipset. The oops occurs as soon as the system has used all the RAM and tries to use swap. The total amount of memory on the machine is 1GB, and himem is enabled. If I turn off himem support the kernel starts to use swap without oopsing. I can provide my kernel .config or more hardware details if that would be useful.

ksymoops 2.4.4 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.
