Ohhh. No I didn't understand that the disk becomes full.
It's not the aic7xxx drivers responsibility to handle/raise ENOSPC. The
driver just executes commands that the higher-level SCSI code sends to it.
I don't know why the newer driver doesn't work whereas the previous driver
did? Perhaps some changes were made to the aic7xxx driver without our
knowing it, and they got lost (replaced over) in our recent release?
