** Description changed: Updated to 2.6.38-2-generic-pae from .38-1 this morning on this SandyBridge system with an ATI graphics card running the opensource -ati driver. I've seen this BUG twice now. Not sure what triggers it. At the time this happened, I was typing up a reply to a bug report in firefox, when suddenly the display stuttered. I had just finished typing "Xorg.0.log from" except what showed in the text area was "Xorg.0.loggggggggggggggggggggg"; then suddenly it switched to a console - where the kernel BUG listed below was displayed. I tapped a few keys + where the kernel BUG listed below was displayed. The music player also + stopped (was playing an internet radio station.) I tapped a few keys and tried vt switching but no go, there seemed to be no response. But then a few moments later I tried again and could switch back to vt7 and - file this report. + file this report. I clicked play on the music player and it went back + to playing music. This box was freshly installed a couple days ago. I installed and set up an NFS server on it last night, and it seemed to work ok. This morning I tried to wake the monitors from power saving, but they never came back. I ssh'd in but didn't see anything unusual at the time other than being on .38-1, however now reviewing my /var/log/kern.log I see it had failed with this same BUG at 8am so guessing it might have been the same problem. Since I was on .38-1 I decided to upgrade to .38-2 before reporting it. Not long after rebooting onto that kernel I saw this BUG - again, exactly as I described above. I rebooted again, and now after - about 6 hrs of uptime have experienced it again. + again, exactly as I described above, except that the music player did + not stop (I was playing music files from an nfs share). I rebooted + again, and now after about 6 hrs of uptime have experienced it again. I notice it is mentioning nfs4 in the error, however afaik I'm just using nfs3 (I don't need any of the nfs4 features). One thing that's odd, since returning to vt7 I can't find the console where the BUG error had been printed out. I took a photo but it's basically just this: [22144.624356] ------------[ cut here ]------------ [22144.624884] kernel BUG at /build/buildd/linux-2.6.38/fs/nfsd/nfs4state.c:3132! - [22144.625703] invalid opcode: 0000 [#1] SMP + [22144.625703] invalid opcode: 0000 [#1] SMP [22144.626185] last sysfs file: /sys/devices/system/cpu/cpu7/cache/index2/shared_cpu_map [22144.627073] Modules linked in: binfmt_misc parport_pc ppdev snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_seq_midi snd_rawmidi snd_seq_midi_event snd_seq snd_timer radeon ttm snd_seq_device drm_kms_helper lp drm snd soundcore joydev serio_raw xhci_hcd snd_page_alloc nfsd exportfs nfs lockd fscache nfs_acl i2c_algo_bit auth_rpcgss parport sunrpc usbhid r8169 hid ahci libahci floppy - [22144.631845] + [22144.631845] [22144.632008] Pid: 1113, comm: nfsd Not tainted 2.6.38-2-generic-pae #29-Ubuntu P67A-UD4/P67A-UD4 [22144.632995] EIP: 0060:[<f8e1bc37>] EFLAGS: 00010246 CPU: 0 [22144.633625] EIP is at nfs4_preprocess_stateid_op+0x327/0x3a0 [nfsd] [22144.634333] EAX: 00000000 EBX: ec32d398 ECX: eed4295c EDX: f754ad80 [22144.635041] ESI: 00000000 EDI: f8e31cc1 EBP: ed991eb0 ESP: ed991e88 [22144.635750] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [22144.636360] Process nfsd (pid: 1113, ti=ed990000 task=f6cd9940 task.ti=ed990000) [22144.637196] Stack: [22144.637418] f8dffe36 ed991ecc f8e16441 ffffffff c5b7275c eed4293c 00000010 eed4293c [22144.638382] f25ef820 f7410000 ed991ecc f8e0c675 eed4295c eed42800 f25ef800 eed42800 [22144.639347] eed42934 ed991f0c f8e0cdc9 f8e11520 ed991ee8 c107f1c5 f7410000 00000002 [22144.640311] Call Trace: [22144.640589] [<f8dffe36>] ? fh_verify+0x136/0x260 [nfsd] [22144.641196] [<f8e16441>] ? nfsd4_encode_operation+0x61/0x180 [nfsd] [22144.641922] [<f8e0c675>] nfsd4_read+0x45/0xc0 [nfsd] [22144.642497] [<f8e0cdc9>] nfsd4_proc_compound+0x369/0x420 [nfsd] [22144.643180] [<f8e11520>] ? nfsd4_decode_compound+0x240/0x330 [nfsd] [22144.643902] [<c107f1c5>] ? groups_free+0x45/0x50 [22144.644437] [<f8e0c630>] ? nfsd4_read+0x0/0xc0 [nfsd] [22144.645021] [<f8dfc913>] nfsd_dispatch+0xd3/0x210 [nfsd] [22144.645643] [<f8d2b559>] svc_process_common+0x2c9/0x5c0 [sunrpc] [22144.646342] [<f8d3758d>] ? svc_xprt_received+0x2d/0x40 [sunrpc] [22144.647030] [<f8d38479>] ? svc_recv+0x479/0x730 [sunrpc] [22144.647648] [<f8d2b92c>] svc_process+0xdc/0x140 [sunrpc] [22144.648260] [<c1525dc0>] ? down_read+0x10/0x20 [22144.648774] [<f8dfc0f0>] nfsd+0xb0/0x140 [nfsd] [22144.649296] [<c1041e6e>] ? complete+0x4e/0x60 [22144.649800] [<f8dfc040>] ? nfsd+0x0/0x140 [nfsd] [22144.650332] [<c1076484>] kthread+0x74/0x80 [22144.704641] [<c1076410>] ? kthread+0x0/0x80 [22144.759083] [<c100b13e>] kernel_thread_helper+0x6/0x10 - [22144.811794] Code: fd ff ff 0f 83 2f ff ff ff eb 8d 31 f6 8d b4 26 00 00 00 00 e9 bc fd ff ff 8b 42 24 31 f6 8b 4d 08 85 c0 89 01 0f 85 aa fd ff ff <0f> 0b 8b 57 24 8b 42 20 85 c0 74 37 8b 55 08 89 02 e9 94 fd ff + [22144.811794] Code: fd ff ff 0f 83 2f ff ff ff eb 8d 31 f6 8d b4 26 00 00 00 00 e9 bc fd ff ff 8b 42 24 31 f6 8b 4d 08 85 c0 89 01 0f 85 aa fd ff ff <0f> 0b 8b 57 24 8b 42 20 85 c0 74 37 8b 55 08 89 02 e9 94 fd ff [22144.867810] EIP: [<f8e1bc37>] nfs4_preprocess_stateid_op+0x327/0x3a0 [nfsd] SS:ESP 0068:ed991e88 [22145.219739] ---[ end trace 42f5b713d5ecc48b ]--- [22231.170388] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: linux-image-2.6.38-2-generic-pae 2.6.38-2.29 Regression: Yes Reproducible: No ProcVersionSignature: Ubuntu 2.6.38-2.29-generic-pae 2.6.38-rc3 Uname: Linux 2.6.38-2-generic-pae i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
