We are running a "QLogic ISP1020 rev 05" SCSI card connected to a 
Clariion / DG storage array. The card is using the 2.4.1 version of the 
qlogicisp driver. It appeared from a SCSI trace that sense data was being
requested, but not making it back out of the driver / card during an
autosense. The sense not coming back was causing the system to get stuck in
a loop during probe of this device (the storage box is configured  for 
failover so all luns are not fully accessible). 

During the debug of the problem we switched to a qlogicisp driver provided by
feral and the problem went away. We verified that the autosense data was
making it back with this driver.

Should we spend time understanding why the autosense was not working on the
2.4.1 driver or is this driver deprecated by the feral driver.

Thanks,
-Mike
