SubjectOOPS in vmscan.c:553
Date
hi there,

we had that OOPS the last night two times. does anyone know what to do? do
you need more info?

ksymoops 2.4.1 on i686 2.4.21. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21/ (default)
-m /boot/System.map-2.4.21 (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.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod
file?
