The usual probe fails with an error message saying that no IRQ could be assigned to the controller, possibly due to a corrupt MP table. The controller works fine with 2.6.30.1 and below. This is how the adapter is normally initialized (messages from 2.6.29.6): aic7xxx 0000:01:03.0: PCI INT A -> GSI 28 (level, low) -> IRQ 28 scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0 <Adaptec aic7892 Ultra160 SCSI adapter> aic7892: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs With 2.6.31-rc1, the kernel freezes with an error message and tries to restart the controller periodically, which always fails.

That sounds like you have an interrupt routing problem, not a problem with the AIC driver. Can you bisect this down to a particular commit?

OK, so I have a 7896 which acts as the root controller of my SCSI test system and it's not showing any such problems. Does this actually work at all, or does it never work (this could indicate an interrupt routing problem). We're also going to need the kernel logs, with the initialisation sequence and the actual errors, please. Thanks, James
