Running kernel 2.4.4 w/Jeff Garzik's via-apic patch, using
reiserfs on a IBM Deskstar on the PDC20265 of a MSI-6321, some
weird shtuff starts happening.

    # mount /dev/hde /mnt
    reiserfs: checking transaction log (device 21:00) ...
    hde: timeout waiting for DMA
    ide_dmaproc: chipset supported ide_dma_timeout func only: 14
    hde: irq timeout: status=3D0x80 { Busy }
    hde: DMA disabled
    ide2: reset: success
    reiserfs: replayed 12 transactions in 44 seconds
    Using r5 hash to sort names
    ReiserFS version 3.6.25

cool!

Now the fun starts: if I start creating a lot of files, I'll
never get to the 1000th, getting the BUG! that follows (the
farthest I've got is B/J/W, i.e. file # 933. Doing a dd instead
of just touching the file is worse). The drive never recovers; I
need to power down the box (a hard reset still leaves it making
these grunging noises).

I attach: the dewhatsitized oops, lspci -vvvxx, hdparm -i
/dev/hde, cat /proc/ide/pdc202xx (but before mounting hde), and
anything else I can think of before hitting y.

Holler if you need anything else.
