Hello, I've got a really similar problem in Mythbuntu 10.04 LTS when suspending/resuming/unloading the pvrusb2 module.
I've already reported it to Ubuntu launchpad: https://bugs.launchpad.net/mythbuntu/+bug/580176 Could you please provide a patch against 2.6.32 which fixes the issue? Best regards, Michal I get the following trace: [ 180.972026] usbcore: deregistering interface driver pvrusb2 [ 180.972083] pvrusb2: Device being rendered inoperable [ 180.972264] pvrusb2: unregistered device video0 [mpeg] [ 180.972345] pvrusb2: unregistered device radio0 [mpeg] [ 180.974077] tuner-simple 1-0061: destroying instance [ 180.974198] tda9887 1-0043: destroying instance [ 180.974332] BUG: unable to handle kernel paging request at 00100100 [ 180.974343] IP: [<00100100>] 0x100100 [ 180.974359] *pde = 6e557067 [ 180.974366] Oops: 0000 [#1] SMP [ 180.974372] last sysfs file: /sys/module/pvrusb2/refcnt [ 180.974379] Modules linked in: vboxnetadp vboxnetflt vboxdrv lirc_serial nfs lockd nfs_acl lirc_dev auth_rpcgss i2c_algo_bit sunrpc tuner_simple tuner_types snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep snd_pcm_oss snd_mixer_oss snd_pcm tda9887 snd_seq_dummy snd_seq_oss snd_seq_midi tda8290 snd_rawmidi snd_seq_midi_event fbcon wm8775 snd_seq tileblit tuner snd_timer font nvidia(P) snd_seq_device bitblit agpgart softcursor cx25840 snd vga16fb soundcore snd_page_alloc pvrusb2(-) dvb_core i2c_nforce2 vgastate lp parport cx2341x serio_raw v4l2_common joydev k8temp videodev v4l1_compat tveeprom usbhid hid usb_storage floppy forcedeth ahci pata_amd [ 180.974486] [ 180.974496] Pid: 804, comm: pvrusb2-context Tainted: P (2.6.32-22-generic #33- Ubuntu) .
