Hi, I'm experiencing the same error with the newest kernel. I have this issue when apparmor is reloading apache rules.

I've just updated the kernel today, the machine it up a bit more than 1 hour. It's a server, so it's double pain. Only reboot helps -- but simple "reboot" hangs, only "reboot -f -h" works. Or hard reset. I'd be really grateful if you had some useful comments on this. Yours, Kamu -- I'm using 140 apparmor HAT profiles with apache2 and mod_apparmor, when I tried to restart apparmor with apparmor_restart the kernel traced out, the process hanged, I wasnt even able to kill it with kill -9 https://bugs.launchpad.net/bugs/273928 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
