Without too many details, the problem seems to be triggered by some sort of race condition between the loading of the sunrpc module and using it (mounting the rpc_pipefs filesystem). This can happen in two places, as far as I can tell... in /etc/init/gssd.conf and /etc/init/idmapd.conf.
On my system, I seem to have worked around the problem by: 1) Disabling GSSD in /etc/default/nfs-common (not used on my system anyways) 2) Adding a delay (sleep 1) just after the do_modprobe sunrpc on line 27 in /etc/init/idmapd.conf Before the workaround I was able to reproduce the problem in a few minutes by continously rebooting the system (basically adding a reboot command to /etc/rc.local). After the workaround, my test system rebooted continously for 90 minutes with no issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310350 Title: Oops __rpc_clnt_handle_event+0x48/0xd0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-saucy/+bug/1310350/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
