[Bug 11194] New: megraid_mbox kernel panic during st driver initialization

[bugme-daemon]

http://bugzilla.kernel.org/show_bug.cgi?id=11194

           Summary: megraid_mbox kernel panic during st driver
                    initialization
           Product: IO/Storage
           Version: 2.5
     KernelVersion: 2.6.25
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: SCSI
        AssignedTo: linux-scsi@vger.kernel.org
        ReportedBy: cshore@fionavar.ca


Latest working kernel version: 2.6.24

Earliest failing kernel version: 2.6.26

Distribution: Debian Lenny (-testing + -unstable + kernel trunk for debian)

Hardware Environment: ASUS P4B 2.0 GHz P4 Motherboard, Dell PERC3/DC (like AMI
MegraRAID Elite 1600) LVD Ultra3 SCSI Adaptor with four 80 GB drives on Channel
0 and a SCSI-U2 Seagate DDS-4 tape drive on Channel 1
Software Environment:  Debian Lenny (up-to-date), with some unstable and tested
with the testing kernel (.25) and the trunk kernel (.26)

Problem Description: The kernel panics (claiming it's in the megaraid_mbox
driver) during boot when the st driver would normally report 

st0: Block limits 1 - 16777215 bytes.

This is after the logical disk has been found and all filesystems mounted, so
the RAID part of the driver is probably fine.


The point at which 

st 0:1:6:0: Attached scsi tape st0
st 0:1:6:0: st0: try direct i/o: yes (alignment 512 B)

appears with .24 is passed before the panic, but I haven't actually seen those
messages as they scroll by too quickly.

Steps to reproduce:

1) Install debian lenny with a .24 kernel (I'm not sure how you would do that
now that .24 is no longer the testing kernel); maybe beta2 would still let you.
2) Install -testing kernel (.25)
3) Attempt to boot using the new kernel
4) Kernel panics, system is unusable

The kernel versions are ambiguous.

Which is the earliest failing kernel version?

Sorry about that; I did latest failing (unless .27 is out; I haven't
tested it). Earliest failing is 2.6.25.

Did you receive my email to the lists?  I don't see it in Google so I'm pinging
to make sure it's not lost given the problems with it not getting to the list.

------- Comment #5 from cshore@fionavar.ca  2008-08-31 22:37 -------
Using a second adaptor card and moving the non-RAID devices off the megaraid
controller solved the panic.  It appears the problem is the non-RAID devices
and may be related the the bug for which there is a patch for newer CERC
firmware (sorry don't have the post url, it was on this list) which deals with
an error in the way the devices are enumerated.

This controller is a Dell PERC3/DCL and has the following BIOS/firmware
revision info:

on boot screen BIOS is listed as 3.35 May 7,2004
Standard Firmware is listed as 199D

in the setup screen, it shows
PERC/CERC BIOS Configuration Utility U827

lspci -vvv gives:
