** Description changed: - - This appears to be a kernel bug related to IO. Although everytime I get this I've got Firefox open, latest incident happened when I had mp3gain running through my music collection. - + The following commits can be cleanly cherry-picked into 2.6.28 to fix this bug: + cce7ade803699463ecc62a065ca522004f7ccb3d + 6bc912b71b6f33b041cfde93ca3f019cbaa852bc 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.
