I'm also experiencing this, but have been unable to obtain the dmesg output since my machine locks up so badly that I can't get any commands to run at all (I can't even find it in /var/log after restarting).
I do remember from the dmesg output that my system is also complaining about nfs4_state_manager. This is with an up-to-date karmic (kernel 2.6.31-3-generic on a 64-bit quad core CPU). -- BUG: soft lockup - CPU#0 stuck for 61s! https://bugs.launchpad.net/bugs/397058 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
