--- Comment #3 from Florian Evers (florian-evers at gmx.de) ---
Hi,

new info: this "crash" can be reproduced very easily here on my system. It is
enough to switch the screen off and on again to find the dump in the dmesg log.
I did not test yet whether it happens during switching off or while switiching
it back on, but I may test that using a second box.

I first noticed that the crash never happens if I work or play on my computer,
but if I come back after a pause I certainly found it in the logs. Thus I got
the assumption that it happens during the power saving phase of the screen.
Interestingly, using the power switch of the screen the dump can be triggered
very easily and 100% reliably.

Hope this helps!

Regards,
Florian
