           Summary: megaraid_mbox kernel panic during boot
           Product: SCSI Drivers
           Version: 2.5
    Kernel Version: 2.6.26, 2.6.32, 3.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Other
        AssignedTo: scsi_drivers-other@kernel-bugs.osdl.org
        ReportedBy: romomoruno@gmail.com
        Regression: Yes


Distribution: Debian Squeeze
Kernel: 2.6.32

Tested kernel not failing: 2.6.18 (etch)
Tested kernel failing: 2.6.26 (lenny), 2.6.32 (squeeze), 3.2 (squeeze-backport)

It appears be a problem with megaraid_mbox kernel module during boot on linux
systems with a LSI Megaraid SCSI adaptor, with three SCSI hard disks in raid 5
and a SCSI DAT Tape (non-RAID device) connected on same adaptor.

I have 17 servers affected with different hardware configurations, and common
point combination is a DAT device tape connected to LSI Megaraid adaptor with
three hard disks array in raid 5.

Disconecting SCSI DAT Tape device from LSI adaptor or connecting it on a second
adaptor solved the problem, but unfortunatelly no option for me.

Hardware configurations:

LSI Megaraid Adaptor    3 SCSI Hard Disks in raid 5    SCSI DAT Tape

--- Comment #10 from justgivemeafkenaccountplx@yahoo.co.uk  2013-03-18 11:52:33 ---
I'm getting a very similar kernel dump on an LSI MegaRaid SATA 300-8X card.
(1000:0409) This card also uses the megaraid_mbox driver. Boots fine, but
crashes consistently when running badblocks -wsv over an array, usually within
an hour. Sometimes it will dump to console and flash the keyboard lights,
sometimes it just hangs.

Server is running nothing else at the moment beyond the basics, and the LSI
currently has no filesystems. I have no reason to suspect the card or the
server as both were running Win2003 server for the last 5 - 6 years without any
issues beyond the fact Windows was running on it :)

Ubuntu 12.04 i386 server, same results with Ubuntu kernel 3.5.0-25 and latest
compiled kernel 3.8.3. If there is any interest here I can post the kernel
dump, hardware details, etc. In a nutshell it's a single hyperthread P4 Xeon
2.4GHz on an Intel PCI-X server board with one jigglybyte of DDR1 ECC. LSI card
is running four 200GB SATA drives in a RAID5, configured with Write Through
caching and DirectIO, 128MB of cache, no backup battery.

I have tried various kernel flags to no avail but seemed to have some success
when I turned off all the performance enhancing settings in the LSI BIOS.
(Multiple PCI delayed transactions, command queuing, HDD write caching) It got
4 - 5 hours through badblocks without crashing but I stopped it as it was
taking forever. Could well have been just a result of decreased load though.
Turning hyperthread on/off makes no difference.

Currently testing various different settings in the LSI BIOS but it's slow
going. Any help would be appreciated here.
