>Description:
I tried building a current kernel yesterday and today (Saturday)
but when booting, during the SCSI device probe, it dumps a whole
mess of information, then indicates it has reset the bus & hangs.
Here is the SCSI hardware in question:

  ahc0 at pci0 dev 15 function 0
  ahc0: interrupting at irq 9
  ahc0: aic7870: Single Channel A, SCSI Id=7, 16/253 SCBs
  scsibus0 at ahc0: 8 targets, 8 luns per target

  cd0 at scsibus0 target 5 lun 0: <PLEXTOR, CD-ROM PX-12TS, 1.01> cdrom removable
  cd0: sync (100.00ns offset 15), 8-bit (10.000MB/s) transfers

I'm just using an old 2940 to handle an old SCSI CD-ROM drive.
