[Bug 13716] New: The AIC-7892P controller does not work any more

           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
    <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

Closing due to the lack of information from the reporter.
