SubjectRE: Consistant complete deadlock with kernel 2.4.16 on an Abit VP6 with dual 1 Gig CPUs and an ICP GDT RAID card
Date
Hi,

i had the same problem, unfortunaly i have not been able to debug it yet.
The problem is on my machine it takes a lot longer to lockup. And i dont
have
the machine local at this time. I tried doing it on a Dual Celeron 450 which
i
do have local, but here i can not get it to lockup.

Maybe u should try debugging (kdb and maybe sysrq?) on a serial console, i
dont
know if u already tried that tho.
