Hello Daniel,

Thanks for the reply, here is the dmesg of such a boot. Its been i
while since i reported something on i915 (this has been stable for a
loong time for me). didnt remember where to file a bug.

in the end, there is a suspend cycle which fixes it.

i will try your patch this afternoon and report back.


hope it helps.

thanks for your help.

Tomas
