Subject2.1.132-ac3 - very strange trap...
Hi, everybody!

I do found VERY ugly bug in 2.1.132-ac3. The machine is 2xPPro200/512, 256MB
RAM, ICP Vortex GDTH and NCR53C810 SCSI controllers, 2 x eepro100 ethernets.
I have a trap during system boot when insmod'ing ncr53c8xx driver outta
initrd image. 53c7,8xx works fine. ncr53c8xx did work fine on 2.1.131-ac13.
The ugly part is the eepro100 in call trace. There are no ethernets when the
trap occures, it does happen during kernel boot... This is the kernel log
of the trap and I'm ready to make all necessary steps to get the bug
squashed:
