Now, I managed to work around this lockup by not using
the AMD IDE chipset support. I no longer get the hang
or the "ata_task_file: unknown command 50" message.
Unfortunately, my 800MHz Athlon machine's performance has
dropped into the toilet with this configuration and 2.5.21.

Also, I am getting some very scary kernel log messages:
hda: lost interrupt
raid0_make_request bug: can't convert block across chunks or bigger than
64k 94712 8
raid0_make_request bug: can't convert block across chunks or bigger than
64k 1340144 12
raid0_make_request bug: can't convert block across chunks or bigger than
64k 1342192 20
I am getting long periodic hangs of up to 10 seconds where the only
thing that
responds is the mouse. Then, everything wakes up for a while.
This kernel has several patches applied, which got it to build:
vmalloc patch
Martin's ide-clean-86 patch
Martin's locks patch
emu10k1 patch
ALSA misc.c patch
