    CVSROOT: /cvs
    Module name: src
    Changes by: csapuntzcvs.openbsd.org 2001/07/31 00:14:05

    Modified files:
            sys/dev/ata : ata_wdc.c
            sys/dev/pci : pciide.c
            sys/dev/ic : wdcvar.h
            sys/dev/atapiscsi: atapiscsi.c

    Log message:
    On DMA timeouts, stop busmaster PCIIDE and reset channel. Avoid reading
    device registers as this may cause lock-ups on some chipsets

    Clean-up in atapiscsi. Get rid of claim_irq. Instead, atapiscsi always
    returns -1 (maybe) from the interrupt handler.
