Testing the fix for bug 1096531 on a MacBook Air results in frequent boot failures (1 failure in every 3 boots on average for me).
Seemingly 1-2 seconds after the kernel hands off to userland, the kernel freezes. I've tried to get output on a serial console, but no joy with this hardware.
The problem is unrelated to Upstart since I subvert Upstart starting by specifying init=... to load a menu system which then starts upstart on request. What I see is that the menu displays, then the kernel dumps details of new usb/bluetooth devices to the console, then the system is dead (no caps light, etc).
Screenshot attached.
This problem may be the same as seen by apw on a raring server system he has (this was discussed on #ubuntu-kernel yesterday).
