The request sense command clobbered the original command, I've changed the
code from doing that, please download a new copy of aic.c file.

Was there a long period between these two messages and the previous ones?
Please try the new aic.c file, it will print out if a different command
is holding up the scsi bus.

For now you could add a quirk entry for this drive to prevent multi-lun
