           Summary: Oops on loading ipaq module since 2.6.26, prevents use
                    of device
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.26
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: USB
        AssignedTo: greg at kroah.com
        ReportedBy: awilliamson at mandriva.com


Latest working kernel version: 2.6.25.4
Earliest failing kernel version: 2.6.26rc4
Distribution: Mandriva Linux
Hardware Environment: i586
Software Environment:
Problem Description:

When testing Windows Mobile 2003 device synchronization, I noticed it was
working fine on one system but not another. I then noticed the working system
was running 2.6.24 and the broken was running 2.6.26, so went to narrow down
the issue.

After testing, I see that when I plug in the device under 2.6.26rc4, a kernel
oops shows up in the logs. lshal output is rather different, synce-trayicon
doesn't see the device, and synce-matchmaker complains about not being able to
find a HAL property (it's looking at the wrong HAL device). Booting a 2.6.24
kernel, everything is fine. I then tried kernel 2.6.25.4, and again, everything
is fine: no oops, synce-trayicon sees the device, so does synce-matchmaker.

This is with stock kernel.org kernel (packaged in Mandriva as kernel-linus),
not Mandriva's normal distro-patched kernel. So it's definitely your bug. :)

I will attach the oops from /var/log/messages . I don't know what else might be
useful - please advise and I'll try to help. I see only four changes to ipaq.c
since October 2007, so hopefully it should be easy to pin this down.

Steps to reproduce:

Plug in an iPaq 1715 - USB ID 03f0:1016 - with kernel 2.6.26.
