Hi,

I have a dual PIII box with 1.25GB of RAM (SMP kernel, devfs, CVS
ALSA, lm_sensors 2.6.3), and tonight I discovered this oops in my log:

ksymoops 2.4.5 on i686 2.4.19-pre9-ac3. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-pre9-ac3/ (default)
-m /boot/System.map-2.4.19-pre9-ac3 (specified)

This oops was preceded 20 minutes earlier by this message:

Jun 4 22:49:52 twopit kernel: Trying to vfree() nonexistent vm area (f8961000)

I think that 2.4.19-pre9-ac3 still has memory problems. Still, at
least it gave me an oops. 2.4.18 spontaneously reboots itself without
warning after between 1 and 2 weeks of uptime.

Cheers,
Chris
