Apparently the bug is present even on the server kernel, as I just got hit with this again.
Uname -a: Linux ubuntu 2.6.27-8-server #1 SMP Thu Nov 6 18:18:16 UTC 2008 x86_64 GNU/Linux And killing Boinc rectifies the system usability. Previous server-kernels worked fine on my machine, what have changed between 2.6.27-7 and 2.6.27-8? -- INFO: task blocked for more than 120 seconds causes system freeze https://bugs.launchpad.net/bugs/276476 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
