When will this fix be released for trusty? I am experiencing this situation about every 3rd day. Have 3 Ubuntu systems tied together - with the system that crashes as the NFS server - along with the primary MythTV service. The other 2 systems read/write to the file system as MythTV services and one is the primary PLEX service. Looking forward to having this annoying situation resolved. Seems to occur when the file system is being used by 2 or more of the secondary servers - however - not been able to pin point the exact usage pattern at the time of the fault. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1376245 Title: remove_proc_entry+0x139/0x1b0() -- name 'fs/nfsfs' Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Trusty: Fix Committed Status in “linux” source package in Utopic: Fix Released Bug description: Ubuntu 14.04 amd64 ii linux-image-3.13.0-37-generic 3.13.0-37.64amd64Linux kernel image for version 3.13.0 on 64 bit x86 SMP sloeuillet@SLoeuillet-DE107:/sfr$ uname -a Linux SLoeuillet-DE107 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Today, I encountered 2 quite identical stack traces in my dmesg, related to nfs : [368973.412120] WARNING: CPU: 1 PID: 15607 at /build/buildd/linux-3.13.0/fs/proc/generic.c:511 remove_proc_entry+0x139/0x1b0() [368973.412122] name 'fs/nfsfs' [368973.412123] Modules linked in: cdc_acm nfsv3 rpcsec_gss_krb5 8021q garp stp mrp llc cuse bnep rfcomm bluetooth nfsv4 nfsd auth_rpcgss nfs_acl nfs lockd sunrpc binfmt_misc fscache hp_wmi sparse_keymap snd_hda_codec_analog snd_hda_intel snd_hda_codec snd_hwdep snd_pcm radeon snd_page_alloc snd_seq_midi snd_seq_midi_event snd_rawmidi snd_seq sp5100_tco snd_seq_device serio_raw snd_timer ttm drm_kms_helper snd kvm edac_core soundcore drm edac_mce_amd k8temp i2c_algo_bit i2c_piix4 tpm_infineon shpchp wmi mac_hid parport_pc ppdev lp parport hid_generic usbhid hid tg3 psmouse ptp pps_core floppy ahci libahci [368973.412164] CPU: 1 PID: 15607 Comm: kworker/u8:1 Tainted: GW 3.13.0-37-generic #64-Ubuntu [368973.412166] Hardware name: Hewlett-Packard HP Compaq dc5850 Small Form Factor/3029h, BIOS 786F6 v03.14 11/15/2011 [368973.412171] Workqueue: netns cleanup_net [368973.412172] 0009 88006a875c80 8171ed09 88006a875cc8 [368973.412176] 88006a875cb8 8106773d 0005 [368973.412179] a05168a8 88011b418b30 0100 88006a875d18 [368973.412182] Call Trace: [368973.412188] [8171ed09] dump_stack+0x45/0x56 [368973.412192] [8106773d] warn_slowpath_common+0x7d/0xa0 [368973.412195] [810677ac] warn_slowpath_fmt+0x4c/0x50 [368973.412198] [81229839] remove_proc_entry+0x139/0x1b0 [368973.412217] [a04f64e2] nfs_fs_proc_net_exit+0x62/0x70 [nfs] [368973.412225] [a04fc5b2] nfs_net_exit+0x12/0x20 [nfs] [368973.412228] [8161b409] ops_exit_list.isra.1+0x39/0x60 [368973.412231] [8161bc90] cleanup_net+0x110/0x250 [368973.412235] [810839c2] process_one_work+0x182/0x450 [368973.412237] [810847b1] worker_thread+0x121/0x410 [368973.412240] [81084690] ? rescuer_thread+0x430/0x430 [368973.412243] [8108b492] kthread+0xd2/0xf0 [368973.412246] [8108b3c0] ? kthread_create_on_node+0x1c0/0x1c0 [368973.412249] [8172f77c] ret_from_fork+0x7c/0xb0 [368973.412251] [8108b3c0] ? kthread_create_on_node+0x1c0/0x1c0 [368973.412253] ---[ end trace bb78fe56a3dcb678 ]--- [368973.448199] WARNING: CPU: 1 PID: 15607 at /build/buildd/linux-3.13.0/fs/proc/generic.c:511 remove_proc_entry+0x139/0x1b0() [368973.448201] name 'fs/nfsfs' [368973.448203] Modules linked in: cdc_acm nfsv3 rpcsec_gss_krb5 8021q garp stp mrp llc cuse bnep rfcomm bluetooth nfsv4 nfsd auth_rpcgss nfs_acl nfs lockd sunrpc binfmt_misc fscache hp_wmi sparse_keymap snd_hda_codec_analog snd_hda_intel snd_hda_codec snd_hwdep snd_pcm radeon snd_page_alloc snd_seq_midi snd_seq_midi_event snd_rawmidi snd_seq sp5100_tco snd_seq_device serio_raw snd_timer ttm drm_kms_helper snd kvm edac_core soundcore drm edac_mce_amd k8temp i2c_algo_bit i2c_piix4 tpm_infineon shpchp wmi mac_hid parport_pc ppdev lp parport hid_generic usbhid hid tg3 psmouse ptp pps_core floppy ahci libahci [368973.448250] CPU: 1 PID: 15607 Comm: kworker/u8:1 Tainted: GW 3.13.0-37-generic #64-Ubuntu [368973.448252] Hardware name: Hewlett-Packard HP Compaq dc5850 Small Form Factor/3029h, BIOS 786F6 v03.14 11/15/2011 [368973.448257] Workqueue: netns cleanup_net [368973.448259] 0009 88006a875c80 8171ed09 88006a875cc8

Picked up these two panics from a few days ago in my logs so unfortunately can't say what was happening at the time. Machine has continued to be usable since. No NFS mounts but possibly related to NFS exports on the box. I am running VMware Workstation on this box. Haven't noticed it with older kernels, but then I wasn't looking for it. I have tried exporting/unexporting NFS and mounting/unmounting those exports but not able to reproduce so far. ** Attachment added: kern.log https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1376245/+attachment/4238997/+files/kern.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1376245 Title: remove_proc_entry+0x139/0x1b0() -- name 'fs/nfsfs' Status in “linux” package in Ubuntu: Confirmed Bug description: Ubuntu 14.04 amd64 ii linux-image-3.13.0-37-generic 3.13.0-37.64amd64Linux kernel image for version 3.13.0 on 64 bit x86 SMP sloeuillet@SLoeuillet-DE107:/sfr$ uname -a Linux SLoeuillet-DE107 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Today, I encountered 2 quite identical stack traces in my dmesg, related to nfs : [368973.412120] WARNING: CPU: 1 PID: 15607 at /build/buildd/linux-3.13.0/fs/proc/generic.c:511 remove_proc_entry+0x139/0x1b0() [368973.412122] name 'fs/nfsfs' [368973.412123] Modules linked in: cdc_acm nfsv3 rpcsec_gss_krb5 8021q garp stp mrp llc cuse bnep rfcomm bluetooth nfsv4 nfsd auth_rpcgss nfs_acl nfs lockd sunrpc binfmt_misc fscache hp_wmi sparse_keymap snd_hda_codec_analog snd_hda_intel snd_hda_codec snd_hwdep snd_pcm radeon snd_page_alloc snd_seq_midi snd_seq_midi_event snd_rawmidi snd_seq sp5100_tco snd_seq_device serio_raw snd_timer ttm drm_kms_helper snd kvm edac_core soundcore drm edac_mce_amd k8temp i2c_algo_bit i2c_piix4 tpm_infineon shpchp wmi mac_hid parport_pc ppdev lp parport hid_generic usbhid hid tg3 psmouse ptp pps_core floppy ahci libahci [368973.412164] CPU: 1 PID: 15607 Comm: kworker/u8:1 Tainted: GW 3.13.0-37-generic #64-Ubuntu [368973.412166] Hardware name: Hewlett-Packard HP Compaq dc5850 Small Form Factor/3029h, BIOS 786F6 v03.14 11/15/2011 [368973.412171] Workqueue: netns cleanup_net [368973.412172] 0009 88006a875c80 8171ed09 88006a875cc8 [368973.412176] 88006a875cb8 8106773d 0005 [368973.412179] a05168a8 88011b418b30 0100 88006a875d18 [368973.412182] Call Trace: [368973.412188] [8171ed09] dump_stack+0x45/0x56 [368973.412192] [8106773d] warn_slowpath_common+0x7d/0xa0 [368973.412195] [810677ac] warn_slowpath_fmt+0x4c/0x50 [368973.412198] [81229839] remove_proc_entry+0x139/0x1b0 [368973.412217] [a04f64e2] nfs_fs_proc_net_exit+0x62/0x70 [nfs] [368973.412225] [a04fc5b2] nfs_net_exit+0x12/0x20 [nfs] [368973.412228] [8161b409] ops_exit_list.isra.1+0x39/0x60 [368973.412231] [8161bc90] cleanup_net+0x110/0x250 [368973.412235] [810839c2] process_one_work+0x182/0x450 [368973.412237] [810847b1] worker_thread+0x121/0x410 [368973.412240] [81084690] ? rescuer_thread+0x430/0x430 [368973.412243] [8108b492] kthread+0xd2/0xf0 [368973.412246] [8108b3c0] ? kthread_create_on_node+0x1c0/0x1c0 [368973.412249] [8172f77c] ret_from_fork+0x7c/0xb0 [368973.412251] [8108b3c0] ? kthread_create_on_node+0x1c0/0x1c0 [368973.412253] ---[ end trace bb78fe56a3dcb678 ]--- [368973.448199] WARNING: CPU: 1 PID: 15607 at /build/buildd/linux-3.13.0/fs/proc/generic.c:511 remove_proc_entry+0x139/0x1b0() [368973.448201] name 'fs/nfsfs' [368973.448203] Modules linked in: cdc_acm nfsv3 rpcsec_gss_krb5 8021q garp stp mrp llc cuse bnep rfcomm bluetooth nfsv4 nfsd auth_rpcgss nfs_acl nfs lockd sunrpc binfmt_misc fscache hp_wmi sparse_keymap snd_hda_codec_analog snd_hda_intel snd_hda_codec snd_hwdep snd_pcm radeon snd_page_alloc snd_seq_midi snd_seq_midi_event snd_rawmidi snd_seq sp5100_tco snd_seq_device serio_raw snd_timer ttm drm_kms_helper snd kvm edac_core soundcore drm edac_mce_amd k8temp i2c_algo_bit i2c_piix4 tpm_infineon shpchp wmi mac_hid parport_pc ppdev lp parport hid_generic usbhid hid tg3 psmouse ptp pps_core floppy ahci libahci [368973.448250] CPU: 1 PID: 15607 Comm: kworker/u8:1 Tainted: GW 3.13.0-37-generic #64-Ubuntu [368973.448252] Hardware name: Hewlett-Packard HP Compaq dc5850 Small Form Factor/3029h, BIOS 786F6 v03.14 11/15/2011 [368973.448257] Workqueue: netns cleanup_net [368973.448259] 0009 88006a875c80 8171ed09 88006a875cc8 [368973.448263] 88006a875cb8 8106773d 0005 [368973.448265]
