Hi,

after running 2.4.20-ac2 for quite some time, I wanted to give
2.4.21-rc6 a try, but I got the following OOPS (copied by hand).
I tried noapic/apic with the same result.

The Mainboard is a EPOX 8K5A3+ with 2 HPT374 controllers onboard, the
RAM is memtested.
lspci -v is attached beneath and I can provide more information if needed.

pikelot:~# ksymoops oops.txt -o /lib/modules/2.4.21-rc6 -m /boot/System.map -KL
