Summary: The AIC-7892P controller does not work any more
Product: SCSI Drivers
Version: 2.5
Kernel Version: 2.6.31-rc1. 2.6.31-rc1-git10
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Other
AssignedTo: scsi_drivers-other@kernel-bugs.osdl.org
ReportedBy: andrej@podzimek.org
Regression: Yes
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
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.
