This has occurred again and although it is not on the most recent kernel it had a slightly different call stack so I thought I would post the log just in case they help. This is on 3.0.0-13-generic.
The interesting bit is that every stack has a call to schedule near the top. This hints to me that something has changed. This crash happened while I was both reading and writing somewhat heavily from different processes (a fast filling log file, an MP3 player, and a large image being loaded). That's as close as I know for how to reproduce. It does not happen often so it's really hard to figure out a pattern. ** Attachment added: "Another set of traces of this freeze." https://bugs.launchpad.net/ubuntu/+source/linux/+bug/863736/+attachment/2630709/+files/kern.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/863736 Title: Processes blocked indefinitely in kernel: queue_log_writer+0x8c/0xd0 [reiserfs] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/863736/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
