This is probably such an obvious thing to ask, but are you able to open
a text console (as opposed to the GUI) and cause a lockup with actions
taken there?  You might get some kernel output that way.  Or attach a
serial terminal as console so you get the kernel output there even when
the lockup happens from within the GUI - and can retain a copy for
easier pasting to a bug report...
