I have seen similar multi minute "hangs" on my Q6600 running amd64 with 2.6.26 kernel. I have no idea what caused it to start happening in 2.6.26. I am now running with nohz=off highres=off which seems to have made the problem go away. 2.6.25 and earlier never do it. It also seems to always be related to disk IO. > [ 691.490083] INFO: task hald-addon-stor:2815 blocked for more than 120 > seconds. > [ 691.490092] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables > this message. > [ 691.490095] hald-addon-st D 7fffffffffffffff 0 2815 2777 > [ 691.490104] ffff81003c981878 0000000000000082 ffffffffa0120dff > ffffffffa004bb00 > [ 691.490117] ffffffffa004bb00 ffff81003dbe7020 ffff81003da16080 > ffff81003dbe72a8 > [ 691.490128] ffffffffa004bb90 ffff81002e0cd400 ffffffffa004bb00 > 0000000000000004 > [ 691.490139] Call Trace: > [ 691.494062] [<ffffffffa0120dff>] :ide_cd_mod:cdrom_newpc_intr+0x0/0x5e1 > [ 691.494077] [<ffffffffa012152b>] > :ide_cd_mod:cdrom_do_newpc_cont+0x0/0x2b > [ 691.494089] [<ffffffff804286e3>] schedule_timeout+0x1e/0xad > [ 691.494114] [<ffffffffa00352e8>] :ide_core:ide_do_request+0x8c7/0x92a > [ 691.494136] [<ffffffffa0034a3d>] :ide_core:ide_do_request+0x1c/0x92a > [ 691.494143] [<ffffffff80427cfb>] wait_for_common+0xcf/0x13a > [ 691.494149] [<ffffffff8022c195>] default_wake_function+0x0/0xe > [ 691.494171] [<ffffffffa003542d>] :ide_core:ide_do_drive_cmd+0xe2/0x109 > [ 691.494186] [<ffffffffa011fd4c>] :ide_cd_mod:ide_cd_queue_pc+0x42/0xca > [ 691.494194] [<ffffffffa011fd4c>] :ide_cd_mod:ide_cd_queue_pc+0x42/0xca > [ 691.494202] [<ffffffff8030d01d>] blk_rq_init+0x1c/0x85 > [ 691.494216] [<ffffffffa011feb3>] > :ide_cd_mod:cdrom_read_tocentry+0xb1/0xc3 > [ 691.494246] [<ffffffff8030fa2e>] blk_end_sync_rq+0x0/0x2e > [ 691.494260] [<ffffffffa012019f>] :ide_cd_mod:ide_cd_read_toc+0x101/0x3d6 > [ 691.494277] [<ffffffffa0120a6f>] > :ide_cd_mod:idecd_revalidate_disk+0x14/0x1b > [ 691.494283] [<ffffffff8029ccfc>] get_super+0x1a/0x8d > [ 691.494289] [<ffffffff802be784>] __invalidate_device+0x3a/0x42 > [ 691.494294] [<ffffffff802be7db>] check_disk_change+0x4f/0x76 > [ 691.494306] [<ffffffffa0118346>] :cdrom:cdrom_open+0x983/0xa14 > [ 691.494315] [<ffffffff802aa6cc>] dput+0x1c/0xdd > [ 691.494320] [<ffffffff8031ae88>] kobject_get+0x12/0x17 > [ 691.494325] [<ffffffff80311cc9>] get_disk+0x40/0x5b > [ 691.494331] [<ffffffff80311cf0>] exact_lock+0xc/0x14 > [ 691.494342] [<ffffffffa011f454>] :ide_cd_mod:idecd_open+0x5b/0x89 > [ 691.494346] [<ffffffff802bf2e1>] blkdev_open+0x0/0x5d > [ 691.494352] [<ffffffff802bef08>] do_open+0xd1/0x2e8 > [ 691.494361] [<ffffffff802bf2e1>] blkdev_open+0x0/0x5d > [ 691.494366] [<ffffffff802bf30f>] blkdev_open+0x2e/0x5d > [ 691.494373] [<ffffffff80299581>] __dentry_open+0x12c/0x238 > [ 691.494383] [<ffffffff802a5369>] do_filp_open+0x3d7/0x7c4 > [ 691.494394] [<ffffffffa0115508>] :cdrom:cdrom_release+0x1a7/0x1e4 > [ 691.494407] [<ffffffff802ac489>] iput+0x27/0x60 > [ 691.494416] [<ffffffff802992bc>] get_unused_fd_flags+0x71/0x115 > [ 691.494424] [<ffffffff802993a6>] do_sys_open+0x46/0xc3 > [ 691.494432] [<ffffffff8020be9a>] system_call_after_swapgs+0x8a/0x8f > [ 691.494444] -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
