           Summary: changing tv channel on a Hauppauge WinTV-USB can cause a
                    kernel panic
           Product: v4l-dvb
           Version: unspecified
     KernelVersion: 2.6.25
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: v4l-other
        AssignedTo: v4l-dvb_v4l-other at kernel-bugs.osdl.org
        ReportedBy: asraniel at fryx.ch


Latest working kernel version: ?
Earliest failing kernel version: 2.6.22, probably earlier
Distribution: ubuntu, open-suse
Hardware Environment: hp pavilion ze4900 with a Hauppauge WinTV-USB III (PAL)
with FM radio Model 568
Software Environment:
Problem Description: When changing tv channel with xawtv (other tv applications
are not even able to show a image with this tv card), the computer locks ups
completely, with the keyboard flashing. There is no indication in any log what
happend. I think it's a kernel panic.

Steps to reproduce: Open xawtv with the mentioned usb tv card, and change
channels during some time, the kernel panic will happen sooner or later. If
kopete is installed, open kopete and go into the preferences and there in the
webcam tab, the crash should happen immediately.


I could reproduce this bug on:
Kubuntu 7.10 (kernel 2.6.22)
Kubuntu 8.04 (kernel 2.6.24)
Kubuntu 8.04, with custom compiled 2.6.25-git13 kernel
Open-suse 10.3

If any other information is needed, i would be happy to provide it.
Steps to reproduce:
