It now doesn't lock up any more - it only halts the system irregularily for a
second or two, while giving the following message:

(collected output from dmesg)

hda: dma_timer_expiry: dma status == 0x21
hda: timeout waiting for DMA

I also noticed this only happened when bonnie'ing on the hda disk (An ugly big
noisy Quantum Bigfoot) - the hdc seems to work flawlessly. So this might as
well be a hardware related problem that previusly didn't lock up the kernel.

Hope that helped a bit and thanks for your *really* fast answer, and keep up
the really good work!

Andreas
