Same problem here only that I am not using PPP as you can see in modules, and a CIFS VFS error appears in the log (I don't know if this could cause the error or if the CIFS error is produced because of the scheduling while atomic.
In my case it is Ubuntu Server 9.10 with all updates applied. Server freezes and has to be rebooted. So upgrading servers to 9.10 can be really dangerous. Same server with version 9.04 works like a charm. kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991257] BUG: scheduling while atomic: swapper/0/0x10000100 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991334] Modules linked in: nls_cp437 cifs cfi_probe gen_probe cfi_util snd_ens1371 gameport scb2_flash mtd snd_rawmidi iptable_filter chipreg snd_seq_device ip_tables map_funcs snd_ac97_codec x_tables ac97_bus i2c_piix4 snd_pcm ppdev dell_wmi psmouse snd_timer parport_pc snd serio_raw sworks_agp lp osst agpgart soundcore parport st shpchp snd_page_alloc dcdbas mptspi mptscsih mptbase scsi_transport_spi floppy starfire mii e1000 megaraid_mbox megaraid_mm kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991428] kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991434] Pid: 0, comm: swapper Tainted: G W (2.6.31-15-generic #50-Ubuntu) PowerEdge 1600SC kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991440] EIP: 0060:[<c0126fc5>] EFLAGS: 00000246 CPU: 1 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991448] EIP is at native_safe_halt+0x5/0x10 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991453] EAX: f705c000 EBX: 00000001 ECX: c1817a80 EDX: 00000000 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991458] ESI: c078ac1c EDI: 179ade96 EBP: f705df58 ESP: f705df58 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991476] eth0: Link is down kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991485] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991490] CR0: 8005003b CR2: b7741014 CR3: 0081a000 CR4: 000006d0 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991496] DR0: 00000000 DR1: 00000000 DR2: 00000000 DR3: 00000000 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991501] DR6: ffff0ff0 DR7: 00000400 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991505] Call Trace: kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991515] [<c010a486>] default_idle+0x46/0xd0 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991523] [<c010202c>] cpu_idle+0x8c/0xd0 kern: 2009-11-30T16:23:13+01:00 Caronte Kernel: [ 302.991532] [<c056c686>] start_secondary+0xc6/0xc8 kern: 2009-11-30T16:23:14+01:00 Caronte Kernel: [ 304.598679] eth0: Link is up, running at 100Mbit full-duplex kern: 2009-11-30T16:23:25+01:00 Caronte Kernel: [ 315.764054] CIFS VFS: No response for cmd 50 mid 11344 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917534] INFO: task events/0:15 blocked for more than 120 seconds. kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917640] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917740] events/0 D c08145c0 0 15 2 0x00000000 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917755] f7095f0c 00000046 f6ab0000 c08145c0 f7065a88 c08145c0 ee6fb07d 00000046 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917779] c08145c0 c08145c0 f7065a88 c08145c0 00000000 00000046 c08145c0 f64e1c00 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917800] f70657f0 c077ce40 c077ce44 ffffffff f7095f38 c056fd66 c180d5c0 c077ce48 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917822] Call Trace: kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917846] [<c056fd66>] __mutex_lock_slowpath+0xc6/0x130 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917856] [<c056fc80>] mutex_lock+0x20/0x40 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917867] [<c04a6f4d>] rtnl_lock+0xd/0x10 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917876] [<c04a91b8>] linkwatch_event+0x8/0x30 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917891] [<c0157a7e>] run_workqueue+0x6e/0x140 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917900] [<c04a91b0>] ? linkwatch_event+0x0/0x30 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917909] [<c0157bd8>] worker_thread+0x88/0xe0 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917920] [<c015c280>] ? autoremove_wake_function+0x0/0x40 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917929] [<c0157b50>] ? worker_thread+0x0/0xe0 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917938] [<c015bf8c>] kthread+0x7c/0x90 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917947] [<c015bf10>] ? kthread+0x0/0x90 kern: 2009-11-30T16:26:11+01:00 Caronte Kernel: [ 480.917958] [<c0104007>] kernel_thread_helper+0x7/0x10 -- BUG: scheduling while atomic: swapper - using ppp [kernel 2.6.31-10.35-generic] https://bugs.launchpad.net/bugs/435917 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
