    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=0x80 { 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.
