apport information ** Summary changed:
- kernel freezes 1-2 seconds after userland starts + kernel disabled console output and keyboard lights in early boot ** Description changed: 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). --- ApportVersion: 2.8-0ubuntu2 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: james 24105 F.... pulseaudio DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=6ceced21-ddb0-4f6c-b5a1-37ced96f43b0 InstallationDate: Installed on 2012-06-12 (225 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Alpha i386 (20120609.1) MachineType: Apple Inc.
