a LOT of scsi timeout errors. i did not notice this on 2.4.0-test12 or test13pre2. when i'm at home i'll see if i can find any pattern or more info, and also test with 2.4.0 final.

I have noticed nearly the same.
When I try to backup (with BRU) from a SCSI disk to my SCSI HP DDS2 DAT the system hangs (SCSI LED on) no disc access possible.

System: 2.4.0 / 2.4.0-ac3
driver: aic7xxx from 2.4.0 and aic7xxx from adaptec (lates version)
compiler: kgcc (egcs)
