Hello, I'm hitting a kernel BUG when unplugging my EyeTV on a MacBook Pro. According to the OS X software, it has an XC5000 tuner, AU8522 demodulator, and AU0828 controller; I hear that it is the same as the Hauppage WinTV-HVR-950Q. I'm running Debian sid with a locally-built 2.6.29.1 kernel. The only modifications from the kernel.org vanilla kernel are the addition of v4l-dvb drivers grabbed from hg today and wireless-testing also current as of today. The text of the BUG is pasted below; the BUG is consistently reproducible either if I unplug the device or if I try to rmmod modules (only did this once and not sure rmmod'ing which dvb module actually caused it). I have unfortunately not checked to see how similar the BUG reports end up over different trials. If you need more context, see http://www.contrib.andrew.cmu.edu/~jwatzman/eyetv/ for various parts of dmesg. "1" was taken right after plugging it in; "2" after waiting a few moments for the firmware to upload; "3" after successfully watching TV for about an hour; and "4" after unplugging the device. Let me know if you need more information! Thanks, Josh Watzman [45664.805473] usb 1-3: USB disconnect, address 8 [45664.806201] BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 [45664.806209] IP: [<ffffffff802506bb>] prepare_to_wait+0x29/0x58 [45664.806222] PGD 7c9ed067 PUD 7c970067 PMD 0 [45664.806229] Oops: 0002 [#1] SMP [45664.806234] last sysfs file: /sys/devices/platform/applesmc.768/light [45664.806238] CPU 0 [45664.806241] Modules linked in: xc5000 tuner au8522 snd_usb_audio snd_usb_lib snd_hwdep au0828 dvb_core videobuf_vmalloc videobuf_core tveeprom v4l2_common radeon drm uvcvideo videodev v4l1_compat v4l2_compat_ioctl32 ipv6 binfmt_misc cpufreq_conservative cpufreq_userspace dm_mod cpufreq_stats cpufreq_powersave kvm_intel kvm fuse cpufreq_ondemand acpi_cpufreq freq_table loop firewire_sbp2 snd_hda_codec_idt snd_hda_intel snd_hda_codec snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_dummy arc4 snd_seq_oss ecb snd_seq_midi snd_rawmidi ath9k mac80211 snd_seq_midi_event snd_seq rfkill snd_timer snd_seq_device joydev rtc_cmos snd video i2c_i801 rtc_core cfg80211 applesmc appletouch soundcore snd_page_alloc rng_core i2c_core rtc_lib led_class ac battery pcspkr button output evdev input_polldev ext3 jbd mbcache ide_cd_mod cdrom sd_mod ata_generic hid_apple ata_piix libata scsi_mod ide_pci_generic firewire_ohci firewire_core piix crc_itu_t ide_core uhci_hcd ehci_hcd sky2 intel_agp thermal processor fan usbhid hid [45664.806377] Pid: 151, comm: khubd Not tainted 2.6.29.1 #1 MacBookPro2,2 [45664.806382] RIP: 0010:[<ffffffff802506bb>] [<ffffffff802506bb>] prepare_to_wait+0x29/0x58 [45664.806391] RSP: 0018:ffff88007e0d3c00 EFLAGS: 00010046 [45664.806395] RAX: 0000000000000000 RBX: ffff88007e0d3c20 RCX: 0000000000000000 [45664.806400] RDX: ffff88007e0d3c38 RSI: 0000000000000246 RDI: ffffffff8053b8a8 [45664.806404] RBP: ffffffff8053b8a8 R08: 0000000000000000 R09: 0000000000002451 [45664.806409] R10: 0000000000000000 R11: ffff880000000000 R12: 0000000000000002 [45664.806413] R13: ffff88004c890000 R14: ffffffffa047f6b8 R15: 0000000000000000 [45664.806418] FS: 0000000000000000(0000) GS:ffffffff80620000(0000) knlGS:0000000000000000 [45664.806423] CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b [45664.806428] CR2: 0000000000000008 CR3: 0000000037841000 CR4: 00000000000026e0 [45664.806432] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [45664.806437] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [45664.806442] Process khubd (pid: 151, threadinfo ffff88007e0d2000, task ffff88007e06f990) [45664.806445] Stack: [45664.806448] ffff880074188190 ffff880074188528 ffff880037909c00 ffffffffa0468ef5 [45664.806456] 0000000000000000 ffff88007e06f990 ffffffff8025050a ffff88007e0d3c38 [45664.806464] ffff88007e0d3c38 ffff88007e0d3c60 ffff880000000000 ffff880074188190 [45664.806473] Call Trace: [45664.806477] [<ffffffffa0468ef5>] ? dvb_net_release+0x60/0xab [dvb_core] [45664.806502] [<ffffffff8025050a>] ? autoremove_wake_function+0x0/0x2e [45664.806510] [<ffffffffa0478962>] ? au0828_dvb_unregister+0x44/0xa6 [au0828] [45664.806524] [<ffffffffa0477036>] ? au0828_usb_disconnect+0x36/0x86 [au0828] [45664.806537] [<ffffffff803b24de>] ? usb_unbind_interface+0x5e/0xe5 [45664.806547] [<ffffffff803a2148>] ? __device_release_driver+0x83/0xa6 [45664.806555] [<ffffffff803a2243>] ? device_release_driver+0x21/0x2d [45664.806561] [<ffffffff803a1874>] ? bus_remove_device+0xa8/0xca [45664.806567] [<ffffffff803a0233>] ? device_del+0x132/0x16c [45664.806574] [<ffffffff803afd77>] ? usb_disable_device+0x7d/0xf4 [45664.806581] [<ffffffff803aba24>] ? usb_disconnect+0x89/0x10e [45664.806588] [<ffffffff803ac971>] ? hub_thread+0x663/0x1066 [45664.806594] [<ffffffff8020a6c9>] ? __switch_to+0xb4/0x399 [45664.806602] [<ffffffff8025050a>] ? autoremove_wake_function+0x0/0x2e [45664.806609] [<ffffffff803ac30e>] ? hub_thread+0x0/0x1066 [45664.806615] [<ffffffff80250197>] ? kthread+0x47/0x73 [45664.806621] [<ffffffff8020d2da>] ? child_rip+0xa/0x20 [45664.806628] [<ffffffff8044d912>] ? _spin_lock+0x5/0x7 [45664.806636] [<ffffffff80250150>] ? kthread+0x0/0x73 [45664.806642] [<ffffffff8020d2d0>] ? child_rip+0x0/0x20 [45664.806648] Code: 1f 00 41 54 41 89 d4 55 48 89 fd 53 48 89 f3 83 26 fe e8 a1 d1 1f 00 48 8b 53 18 48 89 c6 48 8d 43 18 48 39 c2 75 18 48 8b 45 08 <48> 89 50 08 48 89 43 18 48 8d 45 08 48 89 55 08 48 89 43 20 65 [45664.806709] RIP [<ffffffff802506bb>] prepare_to_wait+0x29/0x58 [45664.806717] RSP <ffff88007e0d3c00> [45664.806720] CR2: 0000000000000008 [45664.806725] ---[ end trace 28396efb33fe235a ]--- -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
