Since upgrading to Kubuntu 13.04, I too have been seeing messages "Fixing recursive fault but reboot is needed!". I haven't experienced it "sticking" for a few hours, though -- the system boots OK after a few tries, taking 5 or 10 minutes.
The problem seems to be related to hardware, because it only happens on one of the two boxes I run. I've now installed 3.9.0-030900-generic #201304291257, and I confirm it boots fine (I tried four or five times). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1175660 Title: "BUG: unable to handle kernel paging request at 000000080000003a", "swap_free: Bad swap file entry" and other weirdness during boot since 3.8.0-18 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1175660/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
