Hi. I'm getting this one. The mount.nfs call is being called by the autofs-daemon. It is not directly reproducible, but happens around once a day on a single node on a 48 node cluster. I reported it to the NFS-guys on a .22 kernel, and was directed to the fsdevel list(CC'ed again) back then. Now the problem is reproduces on .26-rc4 Jesper Jun 3 09:46:58 node40 kernel: [17191699.952564] PGD 9f6f5067 PUD baf4f067 PMD 0 Jun 3 09:46:58 node40 kernel: [17191699.952564] CPU 1 Jun 3 09:46:58 node40 kernel: [17191699.952564] Modules linked in: nfs lockd sunrpc autofs4 ipv6 af_packet usbhid hid uhci_hcd ehci_hcd usbkbd parport_pc lp parport amd_rng i2c_amd756 container psmouse serio_raw button pcspkr evdev i2c_core k8temp shpchp pci_hotplug ext3 jbd mbcache sg sd_mod ide_cd_mod cdrom amd74xx ide_core floppy mptspi mptscsih mptbase scsi_transport_spi tg3 ata_generic libata scsi_mod dock ohci_hcd usbcore thermal processor fan thermal_sys fuse Jun 3 09:46:58 node40 kernel: [17191699.952564] Pid: 15602, comm: mount.nfs Not tainted 2.6.26-rc4 #1 Jun 3 09:46:58 node40 kernel: [17191700.727822] RIP: 0010:[graft_tree+77/288] [graft_tree+77/288] graft_tree+0x4d/0x120 Jun 3 09:46:58 node40 kernel: [17191700.727822] RSP: 0000:ffff810068683e08 EFLAGS: 00010246 Jun 3 09:46:58 node40 kernel: [17191700.727822] RAX: ffff8100bf836a90 RBX: 00000000ffffffec RCX: 0000000000000000 Jun 3 09:46:58 node40 kernel: [17191700.983576] RDX: ffff8100fa378500 RSI: ffff810068683e68 RDI: ffff810029252b00 Jun 3 09:46:58 node40 kernel: [17191700.983576] RBP: ffff810029252b00 R08: 0000000000000000 R09: 0000000000000001 Jun 3 09:46:58 node40 kernel: [17191700.983576] R10: 0000000000000001 R11: ffffffff803011c0 R12: ffff810068683e68 Jun 3 09:46:58 node40 kernel: [17191700.983576] R13: 0000000000000000 R14: 000000000000000b R15: 000000000000000b Jun 3 09:46:58 node40 kernel: [17191700.983576] FS: 00007f525595b6e0(0000) GS:ffff8100fbb12280(0000) knlGS:00000000cb307b90 Jun 3 09:46:58 node40 kernel: [17191701.435324] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b Jun 3 09:46:58 node40 kernel: [17191701.435324] CR2: 00000000000000b2 CR3: 000000005ccbc000 CR4: 00000000000006e0 Jun 3 09:46:58 node40 kernel: [17191701.435324] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 Jun 3 09:46:58 node40 kernel: [17191701.435324] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Jun 3 09:46:58 node40 kernel: [17191701.435324] Process mount.nfs (pid: 15602, threadinfo ffff810068682000, task ffff8100bad61700) Jun 3 09:46:58 node40 kernel: [17191701.879311] Stack: ffff810068683e68 ffff810068683e70 ffff810029252b00 ffffffff802b2622 Jun 3 09:46:58 node40 kernel: [17191701.879311] 0000000000000006 0000000000000000 ffff8100c1b72000 ffff8100f68aa000 Jun 3 09:46:58 node40 kernel: [17191701.879311] ffff8100f6540000 ffffffff802b49e9 000000004844f763 0000000000000000 Jun 3 09:46:58 node40 kernel: [17191701.879311] Call Trace: Jun 3 09:46:58 node40 kernel: [17191701.879311] [do_add_mount+162/320] ? do_add_mount+0xa2/0x140 Jun 3 09:46:58 node40 kernel: [17191701.879311] [do_mount+505/592] ? do_mount+0x1f9/0x250 Jun 3 09:46:58 node40 kernel: [17191701.879311] [copy_mount_options+269/384] ? copy_mount_options+0x10d/0x180 Jun 3 09:46:58 node40 kernel: [17191701.879311] [sys_mount+155/256] ? sys_mount+0x9b/0x100 Jun 3 09:46:58 node40 kernel: [17191701.879311] [system_call_after_swapgs+123/128] ? system_call_after_swapgs+0x7b/0x80 Jun 3 09:46:58 node40 kernel: [17191701.879311] Jun 3 09:46:58 node40 kernel: [17191701.879311] Jun 3 09:46:58 node40 kernel: [17191701.879311] RSP <ffff810068683e08> Jun 3 09:46:58 node40 kernel: [17191704.861207] ---[ end trace bc4c286fe026e348 ]--- -- Jesper Krogh -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
