Yes they are. I reproduced the problem.

I managed to reproduce the problem. But it is not "exact science". What I did was: - boot RIPLinux 6.3 USB stick - in boot menu select first option (boot 32 bit kernel) - when asked opt for keyboard selection - select "Slovene" - login as root on VT1 - enter startx - in X right click and select XTerm in menu - in same menu select Setup/<fist option> (for wired network) - wait for the DHCP dialog to appear and click OK - from right click menu select Firefox/Start - ctrl-alt-f2 to VT2 - login as root - enter: reboot -f
It gives the oops in 75% of cases. The steps above do not load any modules that are not loaded by default anyway.
I attach the full dmesg output.
