>Description:
After upgrading to the latest AIC 7xxx driver my system died two times due
to SCSI bus lockups during medium I/O load. Half a minute after the bus
locked up these message appear on the console:

sd1(ahc0:0:1:0): invalid return code from adapter: 3
sd1(ahc0:0:1:0): invalid return code from adapter: 3
sd1(ahc0:0:1:0): invalid return code from adapter: 3
sd1(ahc0:0:1:0): invalid return code from adapter: 3
sd1(ahc0:0:1:0): invalid return code from adapter: 3
[...]
sd1(ahc0:0:1:0): invalid return code from adapter: 3
sd1(ahc0:0:1:0): parity error detected in Data-in phase. SEQADDR(0x155), SCSIRATE(0x88)

>How-To-Repeat:
Try to use the latest AIC 7xxx driver with an Adaptec 3940UW with a fast
U160 harddisk.

>Fix:
Backout revision 1.71 of "syssrc/sys/dev/ic/aic7xxx.c".
