SCSI problems with Vectra XU

Whenever I try using a Linux bootdisk it panics during the SCSI lookup.

The message it gives is:
panic: aic7xxx: unrecoverable BRKADRINT

In swapper task - not syncing

I tried the verbose kboot option (aic7xxx=verbose) and it said something about a timeout.

I have looked around and it appears that SCSI bios < 1.3 might cause some problems. The BIOS on the computer is 1.2S3, anyway to upgrade? Is it possible to use the bios available on adaptecs homepage? Or can you get around this by altering settings?

Worth to mentioning is that the computer works fine with OpenBSD 2.6 but not 2.7, SuSE Linux 6.3 works but not > 6.3 and so on. Wierd.

Any ideas what might help?

Re: SCSI problems with Vectra XU


the best would be to flash latest BIOS on your adapter.
Find it at>support>downloads drivers>your card.

Re: SCSI problems with Vectra XU

It seems that the SCSI driver did not work properly with that Adaptec chipset for a while. Red Hat 5.2, 6.0 and 6.1 worked on the Vectra XU. RH 6.2 did not. RH 7.0 does.
has more information.
