I have a problem with the Adaptec 2940 PCI SCSI controller that I have 
built into my IWill Motherboard (8750-Q controller chip).  I have tried 
without avail to boot up FreeBSD v. 2.1 and I have tried several of the 
snaps for 2.2.  I keep getting the following message:

        ah0:  WARNING no command for SCB 0 (cmdcmplt)
        QOUTCNT == 20

Where QOUTCNT decreases to 0 and the machine then reboots.  I have tried 
new SCSI cables, having only one hard drive (Micropolis or Fujutsu) on 
the controller, running the PCI bus at 60 and 66 MHz, slowing the CPU 
down and even trying to go through the source code and figure out what is 
going on.  In doing that I enabled the debugging and I noticed something 
that I thought peculiar...  The computer seems to have problems after 
probing SCSI ID 7.  ID 7 is the hard drive controller, so why does it 
probe the controller?

Any help / suggestions / questions would be *extremely* appreciated.

System Setup:
	Pentiume 133 w/ 16 MB RAM
	PCI Viper Video Card (2 MB)
	Sound Blaster 16 w/ Adaptec SCSI controller
	2 1-Gig SCSI Hard drives
	1 SCSI CD-ROM
	1 HP 9mm DAT Drive
* Note:  I have tried running the system with nothing more than the video 
card and 1 hard drive, but it still doesn't work.
