Description of problem: Up to, and including kernel 4.0.8-300.fc22.x86_64, my HVR-1950 was working perfectly. On any later kernel I have tried, including 4.2.6-201.fc22.x86_64, the pvr works until I suspend the system to ram. Then pvrusb2 crashes and the pvr is unusable until I reboot. Version-Release number of selected component (if applicable): kernel-4.2.6-201.fc22.x86_64 How reproducible: Every time Steps to Reproduce: 1. Suspend to ram 2. 3.

This bug is still present in kernel-4.4.6-200.fc22.x86_64
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
This bug is still present in Fedora 24 with kernel-4.6.3-300.fc24.x86_64
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 24 kernel bugs. Fedora 24 has now been rebased to 4.7.4-200.fc24. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 25, and are still experiencing this issue, please change the version to Fedora 25. If you experience different issues, please open a new bug report for those.
I confirm this bug is still present in Fedora 24 with kernel-4.7.4-200.fc24.x86_64 After a fresh reboot, unplugging the usb cable of the HVR-1950 OR simply issuing a 'modprobe -r pvrusb2' generates a kernel oops: [ 45.879399] BUG: unable to handle kernel NULL pointer dereference at 0000000000000500 [ 45.879443] IP: [<ffffffffc099d068>] pvr2_v4l2_internal_check+0x48/0x70 [pvrusb2] etc.
