Thank you for the quick answer! I downloaded http://linuxtv.org/hg/v4l-dvb/archive/tip.tar.bz2 and did: make release VER=`uname -r` make sudo make install I had to disable "firedtv" as well, but that is another (ubuntu related) known issue. Unfortunately it's not working and I get the same errors. Is there any way to verify that I'm using the latest driver? Are there any dependencies I'm not aware of? /var/log/messages: Feb 1 00:43:30 niklas-desktop kernel: [ 10.513329] *pde = 00000000 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513338] Modules linked in: snd_hda_codec_analog arc4 ecb mantis(+) mantis_core ir_common ir_core tda665x lnbp21 mb86a16 stb6100 tda10021 tda10023 zl10353 stb0899 stv0299 dvb_core rtl8187 mac80211 led_class eeprom_93cx6 snd_hda_intel snd_hda_codec snd_hwdep snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_dummy snd_seq_oss snd_seq_midi snd_rawmidi snd_seq_midi_event snd_seq iptable_filter cfg80211 lp parport snd_timer snd_seq_device ip_tables x_tables lirc_imon lirc_dev btusb usblp asus_atk0110 nvidia(P) snd soundcore snd_page_alloc ohci1394 skge ieee1394 usbhid sky2 intel_agp agpgart Feb 1 00:43:30 niklas-desktop kernel: [ 10.513386] Feb 1 00:43:30 niklas-desktop kernel: [ 10.513390] Pid: 861, comm: modprobe Tainted: P (2.6.31-17-generic #54-Ubuntu) System Product Name Feb 1 00:43:30 niklas-desktop kernel: [ 10.513393] EIP: 0060:[<f84e9480>] EFLAGS: 00010292 CPU: 0 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513400] EIP is at dvb_unregister_frontend+0x10/0xe0 [dvb_core] Feb 1 00:43:30 niklas-desktop kernel: [ 10.513402] EAX: 00000000 EBX: f616b000 ECX: f6391d40 EDX: 00000000 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513405] ESI: 00000000 EDI: f616b1fc EBP: f61abdec ESP: f61abdc8 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513407] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513413] f61abdec f84ee01e f616b000 00000000 f616b1fc f61abdec f616b000 f616b000 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513420] <0> ffffffff f61abe2c f859b4dc f70fc858 f859fb90 f616b000 00000000 f616b470 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513427] <0> f616b048 f616b464 f616b458 f85af4e0 f616b3fc f616b1ac f616b000 00000000 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513444] [<f84ee01e>] ? dvb_net_release+0x1e/0xb0 [dvb_core] Feb 1 00:43:30 niklas-desktop kernel: [ 10.513452] [<f859b4dc>] ? mantis_dvb_init+0x398/0x3de [mantis_core] Feb 1 00:43:30 niklas-desktop kernel: [ 10.513457] [<f85ac606>] ? mantis_pci_probe+0x1d7/0x2f8 [mantis] Feb 1 00:43:30 niklas-desktop kernel: [ 10.513464] [<c03285ae>] ? local_pci_probe+0xe/0x10 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513468] [<c0329330>] ? pci_device_probe+0x60/0x80 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513474] [<c03a2e30>] ? really_probe+0x50/0x140 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513479] [<c0570cea>] ? _spin_lock_irqsave+0x2a/0x40 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513483] [<c03a2f39>] ? driver_probe_device+0x19/0x20 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513486] [<c03a2fb9>] ? __driver_attach+0x79/0x80 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513490] [<c03a2488>] ? bus_for_each_dev+0x48/0x70 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513493] [<c03a2cf9>] ? driver_attach+0x19/0x20 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513497] [<c03a2f40>] ? __driver_attach+0x0/0x80 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513501] [<c03a26df>] ? bus_add_driver+0xbf/0x2a0 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513504] [<c0329270>] ? pci_device_remove+0x0/0x40 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513508] [<c03a3245>] ? driver_register+0x65/0x120 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513511] [<c0329550>] ? __pci_register_driver+0x40/0xb0 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513516] [<f85ac42d>] ? mantis_init+0x17/0x19 [mantis] Feb 1 00:43:30 niklas-desktop kernel: [ 10.513519] [<c010112c>] ? do_one_initcall+0x2c/0x190 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513523] [<f85ac416>] ? mantis_init+0x0/0x19 [mantis] Feb 1 00:43:30 niklas-desktop kernel: [ 10.513528] [<c0173711>] ? sys_init_module+0xb1/0x1f0 Feb 1 00:43:30 niklas-desktop kernel: [ 10.513532] [<c010336c>] ? syscall_call+0x7/0xb Feb 1 00:43:30 niklas-desktop kernel: [ 10.513612] ---[ end trace fbdc5992aad42451 ]--- lspci: 05:02.0 Multimedia controller: Twinhan Technology Co.
