Several crashes within a few days

Fri Mar 17 12:30:41 UTC 2017

Hi,

it seems to become a problem. Since I upgraded to 

10.3-STABLE FreeBSD 10.3-STABLE #3 r314363: Thu Mar  2

I got several crashes with always the same messages
in /var/log/messages. The system still seems to be running as I can
shut it down but the GPU and with it the video signal is off.

It seems that the GPU hangs several times but the system can recover
most of the time. I do not remember to have seen this message before
the last upgrade.

I am current compiling a new kernel to see if this is already solved.

Erich

PS:

/var/log/messages says
