Ok, I managed to press SysRq-T this time ond got a trace for my hang.
Symbols are resolved by klog. If you prefer ksymopps please tell me, I
used klog because ksymopps seems to drop all lines without symbols.

There seem to be no kernel deamons in the trace? Is this normal, or is
the log buffer too small? If it is the latter, how can I increase its
size?

Kernel was 2.4.6pre5 plus Rik's patch (at the end). I see the same hangs
with the ac series.
