Hi,
Running 2.6.26.1 I am receiving errors similar to the following when stress testing systems:
INFO: task kjournald:1004 blocked for more than 120 seconds. "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. kjournald D ffff81013d347000 0 1004 2 ffff81013cce9de0 0000000000000046 ffff81013cce9d90 ffffffff810478c5 ffff810001069378 ffff81013cdd2cc0 ffff810120454320 ffff81013cdd3010 ffff81013cce9de0 ffffffff81048096 ffff81013cce9db0 0000000000000246 Call Trace: [<ffffffff810478c5>] ? enqueue_hrtimer+0xd1/0xdf [<ffffffff81048096>] ? hrtimer_start+0x122/0x144 [<ffffffffa0023be3>] :jbd:journal_commit_transaction+0xe9/0xd1e [<ffffffff8103bb2d>] ? lock_timer_base+0x26/0x4a [<ffffffff81045534>] ? autoremove_wake_function+0x0/0x38 [<ffffffff8103bba7>] ? try_to_del_timer_sync+0x56/0x62 [<ffffffffa002713e>] :jbd:kjournald+0xc3/0x1fb [<ffffffff81045534>] ? autoremove_wake_function+0x0/0x38 [<ffffffffa002707b>] ? :jbd:kjournald+0x0/0x1fb [<ffffffff810453ff>] kthread+0x49/0x76 [<ffffffff8100cd08>] child_rip+0xa/0x12 [<ffffffff810453b6>] ? kthread+0x0/0x76 [<ffffffff8100ccfe>] ? child_rip+0x0/0x12
This is on a 16 core Intel system with a single SATA disk and 4GB of memory. This particular instance of the error occurred after about an hour.
I was previously using 2.6.24.7 from Fedora 8 and that did not exhibit the problem.
