I tried with nosmp and that gave the same response as noapic, so here
it is: It will keep repeating sym53c8xx_reset until the machine is
reset. I banged on SysRq to try to get some useful information.

Here is a ksymoops trace from 2.4.7-pre7. This kernel still crashes,
but the high i/o performance up until the crash is much better than
under 2.4.6.
>Have you tried 2.2.19, 2.4.4 and -ac kernels?
The -ac kernels haven't booted for me due to the softirq problem, I
believe. I'll try -ac? when the fix from -pre7 (or wherever) is
incorporated. I'll continue trying 2.4.4 and 2.2.19. One thing about
an 8 processor machine with 8GB of ram, I can build a new kernel in
less time than it takes for the machine to reboot...
