i use the motion program to monitor a webcam and a bttv cam. yesterday, i noticed that the bttv monitoring thread wasn't running. when i checked the syslog, i found the following panic. interestingly enough, logwatch didn't even pick it up! i haven't dealt with a linux-type panic before, so i'm hoping someone with much more experience than i can help me figure out what can be gotten from this. here's what was in syslog about it: Mar 15 13:01:31 junior kernel: Unable to handle kernel paging request at virtual address 609fc5f6 Mar 15 13:01:31 junior kernel: printing eip: Mar 15 13:01:31 junior kernel: 609fc5f6 Mar 15 13:01:31 junior kernel: *pde = 00000000 Mar 15 13:01:31 junior kernel: Oops: 0000 [#1] Mar 15 13:01:31 junior kernel: Modules linked in: parport_pc lp parport autofs4 it87 eeprom i2c_sensor i2c_isa smbfs sunrpc ipt_limit iptable_mangle ipt_LOG ipt_MASQUERADE iptable_nat ipt_TOS ipt_REJECT ip_conntrack_irc ip_conntrack_ftp ipt_state ip_conntrack iptable_filter ip_tables dm_mod videobutton battery a c nvidia(U) snd_usb_audio snd_usb_lib snd_rawmidi snd_seq_device ohci_hcd ehci_hcd tuner tvaudio bttv video_buf i2c_algo_bit v4l2_common btcx_risc snd_bt87x i2c_nforce2 i2c_core pwc videodev snd_intel8x0 snd_ac97_codec snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd soundcore snd_page_alloc forcedeth floppy ext3 jbd Mar 15 13:01:31 junior kernel: CPU: 0 Mar 15 13:01:31 junior kernel: EIP: 0060:[<609fc5f6>] Tainted: PF VLI Mar 15 13:01:31 junior kernel: EFLAGS: 00010246 (2.6.10-1.770_FC3) Mar 15 13:01:31 junior kernel: EIP is at 0x609fc5f6 Mar 15 13:01:31 junior kernel: eax: e09cf1a0 ebx: db44d280 ecx: e09cf1a0 edx: db44d280 Mar 15 13:01:31 junior kernel: esi: 00000000 edi: d0e243c0 ebp: d1ebbef8 esp: d1ebbc88 Mar 15 13:01:31 junior kernel: ds: 007b es: 007b ss: 0068 Mar 15 13:01:31 junior kernel: Process motion (pid: 5939, threadinfo=d1ebb000 task=d84d26e0) Mar 15 13:01:31 junior kernel: Stack: e09b6142 d4107ad8 e09cf1a0 d8adec00 011f0002 d4107ad8 011f0002 dff7d9c0 Mar 15 13:01:31 junior kernel: c0163e8c 00001000 dfd20400 d225718c 00000001 c62c5bf4 e08b4953 d225718c Mar 15 13:01:31 junior kernel: cbbd1200 c62c5bf4 c62c5bf4 c62c5bf4 e08b5173 e087a626 00000000 c62c5af4 Mar 15 13:01:31 junior kernel: Call Trace: Mar 15 13:01:31 junior kernel: [<e09b6142>] bttv_do_ioctl+0xbdc/0x130b [bttv] Mar 15 13:01:31 junior kernel: [<c0163e8c>] __getblk+0x24/0x42 Mar 15 13:01:31 junior kernel: [<e08b4953>] ext3_get_inode_loc +0x4f/0x215 [ext3] Mar 15 13:01:31 junior kernel: [<e08b5173>] ext3_do_update_inode +0x2f7/0x31e [ext3] Mar 15 13:01:31 junior kernel: [<e087a626>] journal_get_write_access +0x25/0x2c [jbd] Mar 15 13:01:31 junior kernel: [<e08b5425>] ext3_mark_iloc_dirty +0xf/0x16 [ext3] Mar 15 13:01:31 junior kernel: [<e08b54e0>] ext3_mark_inode_dirty +0x33/0x3a [ext3] Mar 15 13:01:31 junior kernel: [<c01179bf>] __wake_up+0x78/0xde Mar 15 13:01:31 junior kernel: [<e087b66e>] journal_stop+0x39b/0x3a5 [jbd] Mar 15 13:01:31 junior kernel: [<e08b8bf6>] __ext3_journal_stop +0x19/0x34 [ext3] Mar 15 13:01:31 junior kernel: [<e08b3505>] ext3_ordered_commit_write +0xb6/0xc5 [ext3] Mar 15 13:01:31 junior kernel: [<c0148f9a>] mark_page_accessed +0x1c/0x2e Mar 15 13:01:31 junior kernel: [<c0140d2e>] generic_file_buffered_write +0x388/0x467 Mar 15 13:01:31 junior kernel: [<c0104e16>] do_IRQ+0x70/0x7a Mar 15 13:01:31 junior kernel: [<c01035b2>] common_interrupt+0x1a/0x20 Mar 15 13:01:31 junior kernel: [<c0104e16>] do_IRQ+0x70/0x7a Mar 15 13:01:31 junior kernel: [<e08bf217>] ext3_permission+0x0/0xa [ext3] Mar 15 13:01:31 junior kernel: [<c017a034>] __d_lookup+0x128/0x1f5 Mar 15 13:01:31 junior kernel: [<c016f6d5>] do_lookup+0x1f/0x8f Mar 15 13:01:31 junior kernel: [<c0177c60>] dput+0x2c/0x465 Mar 15 13:01:31 junior kernel: [<c0170453>] link_path_walk+0xd0e/0xdc6 Mar 15 13:01:31 junior kernel: [<c0104e16>] do_IRQ+0x70/0x7a Mar 15 13:01:31 junior kernel: [<e08d62d3>] video_usercopy+0x9a/0xf7 [videodev] Mar 15 13:01:31 junior kernel: [<c02fd6cb>] schedule+0x45d/0x4ea Mar 15 13:01:31 junior kernel: [<c02fe00e>] schedule_timeout+0xf8/0x10c Mar 15 13:01:31 junior kernel: [<e09b68a2>] bttv_ioctl+0x31/0x35 [bttv] Mar 15 13:01:31 junior kernel: [<e09b5566>] bttv_do_ioctl+0x0/0x130b [bttv] Mar 15 13:01:31 junior kernel: [<c017400d>] sys_ioctl+0x1d0/0x1eb Mar 15 13:01:31 junior kernel: [<c0103443>] syscall_call+0x7/0xb Mar 15 13:01:31 junior kernel: Code: Bad EIP value. thanks! john
