           Summary: kernel oops in firewire_ohci
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.23.1
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: IEEE1394
        AssignedTo: drivers_ieee1394 at kernel-bugs.osdl.org
        ReportedBy: seraph at xs4all.nl


Most recent kernel where this bug did not occur: 2.6.22.9
Distribution: Gentoo
Hardware Environment: Sparc64 (Blade 100 UltraSPARC 2e)
Software Environment:
Problem Description:

I found a kernel oops in /var/log/messages after booting both my Blade 100s.
The oops appears to have triggered by firewire_ohci, but I'm no kernel hacker
and could be mistaken.

Here is the text of one of them. The one from the other machine is identical
except for the timestamps and machine name.
