The quick fix I'm using is at the end of this email.  The irq was correctly=
 detected before the following commit:

sos         1999/10/09 12:57:15 PDT

    Modified files:
      sys/dev/ata          ata-all.c ata-all.h ata-disk.c ata-disk.h=20
                           ata-dma.c atapi-all.c atapi-all.h=20
                           atapi-cd.c atapi-fd.c atapi-fd.h=20
                           atapi-tape.c atapi-tape.h=20
    Log:
    Add support for the HPT366 chip, this is used on the Abit boards and
    their HotRod controller and on SIIG PCI ultra DMA controller. These
    changes also made lots of the Promise code go away, its all much more
    generic this way.
   =20
    Get rid of atapi_immed_cmd, instead use the queue to move atapi commands
    from interrupt context if nessesary, the entire atapi layer has
    gotten an overhaul.
   =20
    Lots of fixes to utililize the new features in subr_disk.c etc, and
    get rid of the last biots of softc arrays in the drivers, the
    only one left is atadevices which cannot easily go away (yet).
   =20
    Use our own malloc names, its a lot easier to track memory usage this=
 way.
   =20
    General cleanup overall.

Hope this helps!
Greg
