Hello, I'm running a vanilla 2.6.12.3 kernel. This is the second time I see a kernel oops in recent times, but this time I was lucky enough that something ended in my syslog, see the attachment. My hardware are 1 old ff siemens card and 2 new nova-t budget cards (conexant revision). I'm running a plain Debian with vdr 1.3.17 from the e-tobi vdrdevel binary distribution (package version 1.3.17-9). Let me know if you need more log or system data. Thanks, Hanno -------------- next part -------------- Jul 21 23:22:40 localhost kernel: cx22702_set_tps: Autodetecting # The message above was discussed here # http://www.linuxtv.org/pipermail/linux-dvb/2005-June/002900.html # it appears to be harmless and should not be the reason for the kernel oops that follows Jul 21 23:23:22 localhost last message repeated 31 times Jul 21 23:23:22 localhost last message repeated 7 times Jul 21 23:23:22 localhost kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000003 Jul 21 23:23:22 localhost kernel: printing eip: Jul 21 23:23:22 localhost kernel: c0141f87 Jul 21 23:23:22 localhost kernel: *pde = 00000000 Jul 21 23:23:22 localhost kernel: Oops: 0000 [#1] Jul 21 23:23:22 localhost kernel: PREEMPT Jul 21 23:23:22 localhost kernel: Modules linked in: thermal fan button processor ac battery 8250_pnp 8250 serial_core cx88_dvb mt352 or51132 video_buf_dvb cx22702 cx88_blackbird cx8802 cx8800 cx88xx i2c_algo_bit ir_common tveeprom btcx_risc snd_via82xx gameport snd_ac97_codec snd_pc m_oss snd_mixer_oss snd_pcm snd_timer snd_page_alloc snd_mpu401_uart snd_rawmidi snd_seq_device snd soundcore via686a i2c_sensor i2c_viapro li rc_atiusb lirc_dev uhci_hcd usbcore parport_pc parport evdev dvb_ttpci l64781 saa7146_vv video_buf v4l1_compat v4l2_common videodev ves1820 st v0299 tda8083 stv0297 sp8870 firmware_class ves1x93 ttpci_eeprom i2c_core saa7146 nvram genrtc unix Jul 21 23:23:22 localhost kernel: CPU: 0 Jul 21 23:23:22 localhost kernel: EIP: 0060:[cache_flusharray+39/240] Tainted: GF VLI Jul 21 23:23:22 localhost kernel: EFLAGS: 00010086 (2.6.12.3) Jul 21 23:23:22 localhost kernel: EIP is at cache_flusharray+0x27/0xf0 Jul 21 23:23:22 localhost kernel: eax: edde0000 ebx: c1587258 ecx: c14364d8 edx: c14364d8 Jul 21 23:23:22 localhost kernel: esi: e85ba000 edi: 00000286 ebp: ffffffff esp: edde1e08 Jul 21 23:23:22 localhost kernel: ds: 007b es: 007b ss: 0068 Jul 21 23:23:22 localhost kernel: Process vdrdevel (pid: 4195, threadinfo=edde0000 task=ef4c65c0) Jul 21 23:23:22 localhost kernel: Stack: f1b0154c f1b015c0 c02a7754 20000000 c1587258 e85ba000 00000286 edde1e90 Jul 21 23:23:22 localhost kernel: c014226d c14364d8 c1587258 ef0395c0 00000008 ef4c65c0 c0117da6 e85ba000 Jul 21 23:23:22 localhost kernel: c03337a3 ef477b80 c033382b ef0395c0 c043bbc0 ef0395c0 c043bbf0 ef0395c0 Jul 21 23:23:22 localhost kernel: Call Trace: Jul 21 23:23:22 localhost kernel: [dvb_dmxdev_filter_timer+36/144] dvb_dmxdev_filter_timer+0x24/0x90 Jul 21 23:23:22 localhost kernel: [kfree+93/112] kfree+0x5d/0x70 Jul 21 23:23:22 localhost kernel: [free_task+22/48] free_task+0x16/0x30 Jul 21 23:23:22 localhost kernel: [schedule+803/1504] schedule+0x323/0x5e0 Jul 21 23:23:22 localhost kernel: [schedule+939/1504] schedule+0x3ab/0x5e0 Jul 21 23:23:22 localhost kernel: [wait_for_completion+120/208] wait_for_completion+0x78/0xd0 Jul 21 23:23:22 localhost kernel: [default_wake_function+0/32] default_wake_function+0x0/0x20 Jul 21 23:23:22 localhost kernel: [try_to_wake_up+161/192] try_to_wake_up+0xa1/0xc0 Jul 21 23:23:22 localhost kernel: [default_wake_function+0/32] default_wake_function+0x0/0x20 Jul 21 23:23:22 localhost kernel: [wake_up_process+30/32] wake_up_process+0x1e/0x20 Jul 21 23:23:22 localhost kernel: [kthread_stop+85/129] kthread_stop+0x55/0x81 Jul 21 23:23:22 localhost kernel: [pg0+811918027/1069155328] videobuf_dvb_stop_feed+0x5b/0x70 [video_buf_dvb] Jul 21 23:23:22 localhost kernel: [dmx_section_feed_stop_filtering+61/160] dmx_section_feed_stop_filtering+0x3d/0xa0 Jul 21 23:23:22 localhost kernel: [dvb_dmxdev_feed_stop+105/128] dvb_dmxdev_feed_stop+0x69/0x80 Jul 21 23:23:22 localhost kernel: [dvb_dmxdev_filter_stop+137/176] dvb_dmxdev_filter_stop+0x89/0xb0 Jul 21 23:23:22 localhost kernel: [dvb_dmxdev_filter_free+65/288] dvb_dmxdev_filter_free+0x41/0x120 Jul 21 23:23:22 localhost kernel: [__fput+272/304] __fput+0x110/0x130 Jul 21 23:23:22 localhost kernel: [poll_freewait+43/80] poll_freewait+0x2b/0x50 Jul 21 23:23:22 localhost kernel: [sys_poll+484/544] sys_poll+0x1e4/0x220 Jul 21 23:23:22 localhost kernel: [__pollwait+0/208] __pollwait+0x0/0xd0 Jul 21 23:23:22 localhost kernel: [sys_time+23/64] sys_time+0x17/0x40 Jul 21 23:23:22 localhost kernel: [syscall_call+7/11] syscall_call+0x7/0xb Jul 21 23:23:22 localhost kernel: Code: 00 00 00 00 55 57 56 53 83 ec 10 8b 44 24 28 8b 4c 24 24 8b 40 08 89 44 24 0c b8 00 e0 ff ff 21 e0 ff 40 14 8b 69 30 85 ed 74 0a <8b> 45 04 8b 55 00 29 d0 75 61 8b 5c 24 28 8b 44 24 0c 89 0c 24 Jul 21 23:23:22 localhost kernel: <6>note: vdrdevel[4195] exited with preempt_count 2 Jul 21 23:23:23 localhost kernel: cx22702_set_tps: Autodetecting Jul 21 23:23:24 localhost last message repeated 5 times # And this is when I rebooted the system Jul 21 23:29:12 localhost syslogd 1.4.1#17: restart.
