I'd try doing the test on the main console (not X), turn dmesg up (dmesg -n 8) and make sure sysrq is enabled; I'd try sysrq-t or sysrq-w to get stack traces for processes. If really and truly none of that works and you get no messages, that sounds like a tough one to sort out. .28 is getting a bit old, I'd probably try a newer upstream kernel as well. -Eric
