Volker,

Thanks for this report, makes me feel better to know I'm not going totally
nutso. :)

I looked at the difference between the two versions, and there is some code
added to deal with DPMS issues that seems to be the offending bit. I have
been running 4.23 with the patch at
http://people.freebsd.org/~dougb/patch-driver_timers.c for a while now
without seeing those same black flashes. If you could recommend that patch
to the folks who are having problems, then ask them to let me know if that
fixes it for them, I'll let Jamie know about this.

Thanks!

Doug
