           Summary: aacraid driver fails with Dell PowerEdge Expandable RAID
                    Controller 3/Di
           Product: SCSI Drivers
           Version: 2.5
     KernelVersion: 2.6.22.9
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: AACRAID
        AssignedTo: scsi_drivers-aacraid at kernel-bugs.osdl.org
        ReportedBy: hawk at pld-linux.org


Most recent kernel where this bug did not occur: 2.6.20.4 (see description)
Distribution: PLD Linux Distribution 2.0 (Ac)

Hardware Environment:
Dell PowerEdge 1650 with Dell PowerEdge Expandable RAID Controller 3/Di (rev
01), 2 disks, mirror, PCI ID 1028:000a

Problem Description:

System does not boot at all using aacraid SCSI driver with Dell PERC 3/Di
controller. Machine is currently running kernel 2.6.20.4 and it works
perfectly. Few days ago I was trying upgrade to 2.6.22.9 and system failed to
boot.

Driver correctly detects controller and then following messages are displayed
on console:

scsi 0:0:0:0 Direct-Access DELL mirror V1.0 PQ: 0 ANSI: 2
AAC:AAC received an unrecognized command [601]
aacraid: Host adapter abort request (0,1,0,0)
aacraid: Host adapter abort request (0,1,0,0)
aacraid: Host adapter reset request. SCSI hang ?
scsi 0:1:0:0 scsi: Device offlined - not ready after error recovery

... and so on for every scsi id and scsi host (0:1:1:0, 0:1:2:0, ... ,
0:2:15:0). Then system fails with kernel panic: unable to mount root filesystem
which is obvious.

I wasn't trying to build 2.6.20.x kernel series newer than .4. I've tried
2.6.21.4 and 2.6.22.5 and they failed same way 2.6.22.9 did.

Steps to reproduce: try to boot with root fs on machine with Dell PERC 3/Di.
