** Description changed: - The following commits can be cleanly cherry-picked into 2.6.28 to fix this bug: - cce7ade803699463ecc62a065ca522004f7ccb3d - 6bc912b71b6f33b041cfde93ca3f019cbaa852bc + "INFO: task blocked for more than 120 seconds" is a diagnostic message + for when a process that wants to run is blocked from running for a long + time. - Original description: - Npviewer segfaults when visiting a website on Firefox with flash content. After that thunderbird, firefox stop responding and they have to be force quitted. Their processes (thunderbird.bin and firefox) can't be killed with kill -9 or killall. After a while these messages turn up on terminal: - - (taken from kern.log) - Sep 30 22:37:19 ubuntu kernel: [19808.392380] INFO: task thunderbird-bin:28288 blocked for more than 120 seconds. - Sep 30 22:37:19 ubuntu kernel: [19808.392418] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. - - I have to reboot using Sysreq + reisub. - - This happens at least once a day on fully updated (as of 30.09.2008) - Intrebid Ibex on x86_64. - - uname -a: Linux ubuntu 2.6.27-4-generic #1 SMP Wed Sep 24 01:29:06 UTC - 2008 x86_64 GNU/Linux - - Attached kern.log with relevant bits of two separate occasions. + This bug report refers to a specific problem with idle-priority + scheduling that has now been fixed. If you are up to date and are still + getting the "task blocked" message, it is a different bug, so please + file a new bug report.
