Hi,

i just received an oops after the command 'ls'. Below is the output of
ksymoops. Also note that kernel 2.4.6 was stable so far, and i just
patched it with ext3-0.9.0 two days ago. After the oops i couldn't login
on another vt any more. And just after a reboot i received another oops
where the keyboard froze completely, so no logs from this one.

ksymoops 2.4.1 on i686 2.4.6.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.6/ (default)
     -m /boot/System.map-2.4.6 (specified)

Please note that during this oops i had the following additional modules
loaded: i2c-matroxfb.o matroxfb_crtc2.o and matroxfb_maven.o.
They enable the 2nd video output on the Matrox G400 videocard.

If you need more infos, i will be glad to help.

Bye, Stefan
