The only reference to i2c is the last sysfs file. I'm not even sure why mplayer would read i2c adapter names. How reproducible is this bug? Does a mere "cat /sys/devices/pci0000:00/0000:00:01.1/i2c-adapter/i2c-1/name" trigger it? It's not very reproducible, it happend from time to time with random clips and actually, it seems to have gone away since 2.6.30.5, therefore I would be ok with closing this bug. No, »cat /sys/devices/pci0000:00/0000:00:01.1/i2c-adapter/i2c-1/name« doesn't trigger it. Thank you for looking into this! Kind regards, Kai Wasserbäch This doesn't look like an I2C issue, so I'm moving it to a more suitable product. |
While watching a short film with mplayer, I got the following: BUG: unable to handle kernel paging request at 41509d64 IP: [<c015a1cd>] find_get_page+0x3d/0xb0 *pde = 00000000 Oops: 0000 [#1] last sysfs file: /sys/devices/pci0000:00/0000:00:01.1/i2c-adapter/i2c-1/name Modules linked in: radeon drm ipv6 af_packet aes_i586 aes_generic sd_mod scsi_mod psmouse snd_emu10k1_synth snd_emux_synth snd_seq_virmidi snd_seq_midi_emul snd_emu10k1 snd_ac97_codec ac97_bus snd_pcm_oss snd_mixer_oss joydev snd_pcm snd_page_alloc snd_util_mem snd_hwdep snd_seq_dummy snd_seq_oss snd_seq_midi snd_rawmidi snd_seq_midi_event snd_seq snd_timer snd_seq_device emu10k1_gp gameport usbhid snd soundcore pcspkr button processor ext3 jbd ohci_hcd ohci1394 nvidia_agp ieee1394 ide_cd_mod cdrom ehci_hcd usbcore agpgart thermal fan thermal_sys unix Pid: 3759, comm: mplayer Not tainted (2.6.30.4-cabal #1) A7N8X-X EIP: 0060:[<c015a1cd>] EFLAGS: 00210203 CPU: 0 EIP is at find_get_page+0x3d/0xb0 EAX: 41509d5f EBX: 41509d60 ECX: 41509d60 EDX: 00000000 ESI: f6515edc EDI: f35fed0c EBP: d6542ce4 ESP: f6515e38 DS: 007b ES: 007b FS: 0000 GS: 0033 SS: 0068 Process mplayer (pid: 3759, ti=f6514000 task=f653c000 task.ti=f6514000) Stack: d6542ce8 f6515ea8 00000211 41509d60 00000000 f6515edc 00000001 d6542ce4 c015bdb0 00000001 14bdd6c2 0000395f 00211000 00000000 f6515f60 f3313580 00000000 f6515f24 00000000 00000000 00000210 00000212 f33135c0 d6542c3c Call Trace: [<c015bdb0>] ? generic_file_aio_read+0x1f0/0x690 [<c01806a5>] ? do_sync_read+0xd5/0x120 [<c0133250>] ? autoremove_wake_function+0x0/0x50 [<c0261653>] ? tty_write+0x1a3/0x1e0 [<c01de11c>] ? security_file_permission+0xc/0x10 [<c018074a>] ? rw_verify_area+0x5a/0xd0 [<c01805d0>] ? do_sync_read+0x0/0x120 [<c018132d>] ? vfs_read+0x9d/0x140 [<c01814a1>] ? sys_read+0x41/0x80 [<c0102d44>] ? sysenter_do_call+0x12/0x22 Code: b4 26 00 00 00 00 8b 54 24 08 8b 04 24 e8 4c 5b 0b 00 85 c0 89 c7 74 66 8b 18 f6 c3 01 75 e7 8d 43 ff 89 5c 24 0c 83 f8 fd 77 db <8b> 53 04 85 d2 74 d4 8d 42 01 8d 73 04 89 44 24 04 89 d0 8b 6c EIP: [<c015a1cd>] find_get_page+0x3d/0xb0 SS:ESP 0068:f6515e38 CR2: 0000000041509d64 ---[ end trace 301922c48df410cd ]--- It sounds somewhat like #13364, but no video driver is mentioned in the trace and I2C is, so I thought it to be better to open a new bug report. If it's the same issue, feel free to merge them. I'm running a vanilla 2.6.30.4, no patches applied. lspci -vvv output: $ lspci -vvv 00:00.0 Host bridge: nVidia Corporation nForce2 IGP2 (rev c1) Subsystem: ASUSTeK Computer Inc.
