Comment 14 for bug 1021924

This appears in dmesg:

The last 2 messages appear to match Daniel's suggestion of fdi train fail.

Is this enough information to go on for now? I installed a 3.6-rc5 kernel, but upon booting it, my mouse and keyboard were not working under X, so I was unable to log in, switch to a console, or even reboot without using the hardware reset button.
