Comment 6 for bug 318360

I have installed current jaunty and have the same bug. It happens during shutdown/reboot.
The stacktrace looks the same, only the process that caused a bus is either NetworkManager or wpa_supplicant. Killing those processes before shutdown/reboot fixes the problem.
In intrepid everything works fine. At first I thought that I have https://bugs.launchpad.net/bugs/317775, but after removing "quiet splash" from kernel command line I see kernel oops with stacktrace at shutdown. Upstream seems to have a patch for this bug http://bugzilla.kernel.org/show_bug.cgi?id=11326. May be some reordering of shutdown sequence will help too.
Unfortunately I do not know how to have this stacktrace and attach it here, cause it happens at shutdown and doesn't go to logs.
