--- Comment #8 from Jerome <an.inbox at free.fr> ---
I spoke too quickly once again. I had a lock-up after leaving the PC for over a
day suspended, then on resume the usual lock-up when switching to graphic mode,
with a dark blank screen. With the nightly kernel indicated in my previous
comment.
As usual, it required a forced power down and reboot and left no trace. That
looks like a tough one to debug...

As requested by Ander I will open a new kernel bug and put the reference here.
