I had two or three days of suspend working perfectly, but now it consistently crashes the computer.
suspending on console (tty3) without X running works, but the crash happens when I switch back to X windows after un-suspending. (with Ctrl-alt-1)
I see errors on the console that relate to the pcibus and dmesg contains a reference to “GPU has fallen off the bus”
