           Summary: cciss driver hangs on boot
           Product: IO/Storage
           Version: 2.5
     KernelVersion: 2.4.37
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: SCSI
        AssignedTo: linux-scsi@vger.kernel.org
        ReportedBy: rich@hq.vsaa.lv


Latest working kernel version: 2.4.25
Earliest failing kernel version: 2.4.28
Distribution: slackware 11.0
Hardware Environment: HP ProLiant DL360 G3
Software Environment:
Problem Description:

boot of kernels 2.4.28-37 hangs on "partition check" step.
latest kernel that boots is 2.4.25.
26 and 27 fail to compile on that machine, so nailing this down to a precise
version has been problematic.
cciss driver is compiled in the kernel.

more information probably will be needed, i'll be happy to provide it.

adapter :
00:04.0 RAID bus controller: Compaq Computer Corporation Smart Array 5i/532
(rev 01)

Steps to reproduce:
boot a kernel 2.4.28 to 2.4.37 on such a hw configuration

instead of some bogus numbers

Hi,

sorry for the delay, I've not been much available these weeks.

With which compiler(s) have you tried ? I have vague memories of a few of the
changes you outlined above (eg: gcc-3.4 fixes). Those were done with a lot of
care, so I would bet they're OK. But maybe the updates 1-5 contain something
wrong. I still find it strange that nobody encountered any problem with this
driver for the last 4 years. Do you think that your setup has something
specific
which could explain why others are not affected ?

Willy
