This time for a change I did notice that first after I made number of tunnings to different channels few minutes before the crash I was not able to tune to in to any frequency. My system without the card did work for a month with no problem therefore the problem is definetly with the card or the way the in kernel driver for it works. Please take a look at the error and let me know if there is any thing I can do to get rid of this problem :( BUG: unable to handle kernel NULL pointer deference at 00000000000000a8 IP: [<ffffffffa01d38a0>] cx23885_video_wakeup+0x20/0x160 [ cx23885] PGD 127716067 PUD 12b2f1067 PMD 0 Oops: 0000 [#1] SMP Modules linked in: des_generic ecb md4 sha256_generic md5 hmac nls_cp1250 cifs ipv6 dvb_ttpci saa7146_vv ttpci_eeprom saa7146 ir_rc6_decoder ir_lirc_codec lirc_dev w83627ehf hwmon_vid phx_k8(O) mperf(O) thermal fan rc_imon_pad imon usbhid stb6100 stv090x cx23885 btcx_risc psmouse snd_hda_codec_realtek altera_ci videobuf_dvb tda18271 pcspkr altera_stapi tveeprom cx2341x videobuf_dma_sg k10temp dvb_core rc_core v4l2_common xhci_hcd r8169 videodev mii media snd_hda_codec_hdmi videobuf_core ohci_hcd sr_mod cdrom snd_hda_intel ehci_hcd snd_hda_codec snd_hwdep snd_pcm usbcore snd_page_alloc usb_common snd_timer snd parport_pc parport processor thermal_sys CPU 1 Pid: 0, comm: swapper/1 Tained: G 0 3.7.0-rc5 #1 System manufacuter System Product Name/E35M1-M PRO RIP: 0010:[<ffffffffa01d38a0>] [<ffffffffa01d38a0>] cx23885_video_wakeup+0x20/0x160 [ cx23885] RSP: 0018:ffff88013ed03de8 EFLAGS: 00010082 RAX: ffffc90011400000 RBX: 0000000000000000 RCX: 0000000000000060 RDX: 00000000ffffffff RSI: ffff880137586070 RDI: ffff880137584000 RBP: ffff880137586070 R08: 000000000000000a R09: 0000000000000000 R10: 00000000000003cb R11: 00000000000003ca R12: 0000000000000000 R13: 00000000ffffffff R14: 00000000ffffffff R15: 00000000ffffffff FS: 00007f1b27b73700(0000) GS:ffff88013ed00000(0000) knlGS:00000000f1bfab40 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00000000000000a8 CR3: 000000012743b000 CR4: 00000000000007e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process swapper/1 (pid: 0, threadinfo ffff88013a8a6000, task ffff88013a87c080 Stack: ffff88013ed03e38 ffff88013ed03df8 00000000ffffffff 00000000ffffffff ffff880137584000 0000000000000000 00000000ffffffff 00000000ffffffff 00000000ffffffff ffffffffa01d4360 ffff880137584000 00000000ffffffff Call Trace: <IRQ> [<ffffffffa01d4360>] ? cx23885_video_irq+0x100/0x1c0 [ cx23885] [<ffffffffa01d7ea4>] ? cx23885_irq+0x434/0x920 [ cx23885] [<ffffffff8109cab9>] ? rcu_process_callbacks+0x459/0x540 [<ffffffffa00067a5>] ? azx_interrupt+0x105/0x1b0 [snd_hda_intel] [<ffffffff81096624>] ? handle_irq_event_percpu+0x54/0x1f0 [<ffffffff810967f6>] ? handle_irq_event+0x36/0x60 [<ffffffff8109967c>] ? handle_fasteoi_irq+0x4c/0xe0 [<ffffffff81003df5>] ? handle_irq+0x15/0x20 [<ffffffff81003ac3>] ? do_IRQ+0x53/0xd0 [<ffffffff814ab9ea>] ? common_interrupt+0x6a/0x6a <EOI> [<ffffffffa0012005>] ? acpi_idle_enter_simple+0xb5/0xe6 [processor] [<ffffffffa0012000>] ? acpi_idle_enter_simple+0xb0/0xe6 [processor] [<ffffffff813e6b12>] ? cpuidle_idle_call+0xa2/0x270 [<ffffffff8100b24a>] ? cpu_idle+0x7a/0xd0 Code: 12 2d e1 e9 52 ff ff ff 0f 1f 00 41 57 41 56 41 89 d6 41 55 41 54 55 48 89 f5 53 48 83 ec 18 48 8b 1e 48 39 de 0f 84 e1 00 00 00 <66> 3b 93 a8 00 00 00 41 89 d4 0f 88 b4 00 00 00 48 8d 43 c8 45 RIP [<ffffffffa01d38a0>] cx23885_video_wakeup+0x20/0x160 [ cx23885] RSP <ffff88013ed03de8> CR2: 00000000000000a8 Kernel panic – not syncing: Fatal exception in interrupt panic occured, switching back to text console Regards, _WM -- 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
