kernel BUG at drivers/scsi/aic94xx/aic94xx_hwi.h:354!

whee!  That's BUG_ON(!list_empty(&ascb->list));

yet anoher scsi driver with no entry in MAINTAINERS.  Darrick, maybe?

Quite honestly, that's the reality of the situation for (IMO) the majority of SCSI drivers. They just don't really have maintainers at all, so it winds up falling onto the subsystem maintainer(s) by default.

Gilbert_Wu@xxxxxxxxxxx just posted a patch to the driver, so he should probably be kept in the loop.
