Attached is a dmesg with some sort of traceback that shows a failure involving ath9k; I don't know that it's directly related to my problem, since I don't get it all the time, but it is suspicious. I have another dmesg from another boot that shows pretty much the same thing; I can provide it if requested.
Here's what I figure is the important bit at the end: [ 8877.760576] wlan0: no probe response from AP 00:16:b6:34:22:b2 - disassociating [ 8877.915547] BUG: unable to handle kernel paging request at 80808080 [ 8877.915574] IP: [<c01bb761>] put_page+0x11/0x100 [ 8877.915606] *pde = 00000000 [ 8877.915620] Oops: 0000 [#1] SMP [ 8877.915636] last sysfs file: /sys/devices/virtual/backlight/acpi_video0/brightness [ 8877.915651] Modules linked in: cbc aes_i586 aes_generic binfmt_misc ppdev dm_crypt snd_hda_codec_realtek snd_hda_intel snd_hda_codec arc4 snd_hwdep ecb snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_dummy snd_seq_oss snd_seq_midi snd_rawmidi ath9k snd_seq_midi_event snd_seq snd_timer mac80211 snd_seq_device ath acer_wmi snd uvcvideo soundcore snd_page_alloc videodev atl1c cfg80211 v4l1_compat psmouse serio_raw led_class lp parport fbcon tileblit font bitblit softcursor i915 usbhid drm i2c_algo_bit intel_agp agpgart video output [ 8877.915859] [ 8877.915876] Pid: 3208, comm: phy0 Not tainted (2.6.31-19-generic #56-Ubuntu) AO532h [ 8877.915892] EIP: 0060:[<c01bb761>] EFLAGS: 00010282 CPU: 0 [ 8877.915910] EIP is at put_page+0x11/0x100 [ 8877.915924] EAX: 80808080 EBX: 80808080 ECX: d4b4c540 EDX: c3db4040 [ 8877.915939] ESI: d4b4c540 EDI: d4b4c540 EBP: e0131d84 ESP: e0131d70 [ 8877.915953] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [ 8877.915970] Process phy0 (pid: 3208, ti=e0130000 task=e0003240 task.ti=e0130000) [ 8877.915982] Stack: [ 8877.915990] 00000000 00000000 00000001 d4b4c540 d4b4c540 e0131d94 c0493917 d4b4c540 [ 8877.916010] <0> 00000009 e0131da0 c0493452 f69881a0 e0131da8 c04934ec e0131de4 f8dc2eaf [ 8877.916010] <0> 00000000 00000000 00000000 00000000 f6989148 00000000 c3db4024 c3db4020 [ 8877.916010] Call Trace: [ 8877.916010] [<c0493917>] ? skb_release_data+0x87/0xa0 [ 8877.916010] [<c0493452>] ? __kfree_skb+0x12/0x90 [ 8877.916010] [<c04934ec>] ? consume_skb+0x1c/0x40 [ 8877.916010] [<f8dc2eaf>] ? ieee80211_tx_status+0x43f/0x470 [mac80211] [ 8877.916010] [<f8e83b24>] ? ath_tx_complete+0x124/0x150 [ath9k] [ 8877.916010] [<f8e79df7>] ? ath9k_hw_setup_calibration+0x97/0x140 [ath9k] [ 8877.916010] [<f8e83bc1>] ? ath_tx_complete_buf+0x71/0xc0 [ath9k] [ 8877.916010] [<c014b295>] ? __do_softirq+0xe5/0x1a0 [ 8877.916010] [<f8e84f94>] ? ath_draintxq+0x134/0x280 [ath9k] [ 8877.916010] [<f8e861ee>] ? ath_drain_all_txq+0xce/0x140 [ath9k] [ 8877.916010] [<f8e820e2>] ? ath_set_channel+0x82/0x200 [ath9k] [ 8877.916010] [<f8e7eaae>] ? ath_update_chainmask+0x7e/0x90 [ath9k] [ 8877.916010] [<f8e82407>] ? ath9k_config+0x1a7/0x200 [ath9k] [ 8877.916010] [<f8dc2972>] ? ieee80211_hw_config+0x72/0xb0 [mac80211] [ 8877.916010] [<f8dc7146>] ? ieee80211_scan_work+0xb6/0x220 [mac80211] [ 8877.916010] [<c056f07c>] ? schedule+0x40c/0x730 [ 8877.916010] [<c015794e>] ? run_workqueue+0x6e/0x140 [ 8877.916010] [<f8dc7090>] ? ieee80211_scan_work+0x0/0x220 [mac80211] [ 8877.916010] [<c0157aa8>] ? worker_thread+0x88/0xe0 [ 8877.916010] [<c015c0f0>] ? autoremove_wake_function+0x0/0x40 [ 8877.916010] [<c0157a20>] ? worker_thread+0x0/0xe0 [ 8877.916010] [<c015bdfc>] ? kthread+0x7c/0x90 [ 8877.916010] [<c015bd80>] ? kthread+0x0/0x90 [ 8877.916010] [<c0104007>] ? kernel_thread_helper+0x7/0x10 [ 8877.916010] Code: fe ff ff f0 80 23 fb eb dc 90 55 b8 30 be 1b c0 89 e5 e8 93 d7 f9 ff 5d c3 90 55 89 e5 83 ec 14 89 5d f4 89 c3 89 75 f8 89 7d fc <66> f7 00 00 c0 0f 85 cc 00 00 00 f0 ff 48 04 0f 94 c0 84 c0 74 [ 8877.916010] EIP: [<c01bb761>] put_page+0x11/0x100 SS:ESP 0068:e0131d70 [ 8877.916010] CR2: 0000000080808080 [ 8877.917246] ---[ end trace 9e1818652b081caf ]--- ** Attachment added: "dmesg with failure reported" http://launchpadlibrarian.net/49519284/bugreport1.txt -- kernel 2.6.31-19 causing lockups on Acer Aspire One AO532H https://bugs.launchpad.net/bugs/518666 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
