>Description:

this PR is similar to PR 11522, but this time for the ahc driver.
pretty much the same deal.  run tosha, get this on the console:

cd0(ahc0:3:0): SCB 1d - timed out while idle, SEQADDR == 0xd
SCSIRATE == 0x0
cd0(ahc0:3:0): Queuing a BDR SCB
cd0(ahc0:3:0): Bus Device Reset Message Sent
cd0(ahc0:3:0): no longer in timeout, status = 0
ahc0: Bus Device Reset on A:3. 1 SCBs aborted
ahc0: target 3 synchronous at 10.0MHz, offset = 0xf


and tosha spews:
