Bug#699345: xserver-xorg-video-ati: Xorg crashes with, black/white screen since wheezy update to 6.14.4-6



Hi.
The problem is still the same but without the segfaults in the logs.

But in syslog I found these lines:

Feb  6 14:41:13 christian kernel: [   39.200232] eth0: no IPv6 routers present

Feb  6 14:41:20 christian kernel: [   45.997144] radeon 0000:00:01.0: GPU reset succeed

I hope that helps.

Best regards,

See

(testing with that kernel would be welcome).
