Freezes the system and requires hard reset.

Comment 1 Michel Dänzer 2015-05-13 07:13:13 UTC

Please attach the full dmesg output.

Can you reproduce this problem by doing something in particular, or is it random? Is it a regression, i.e. didn't it happen with an older kernel version?

Comment 3 Apostolos B. 2015-05-13 08:00:30 UTC

I had similar crashes requiring a hard reset but the log messages were different. This is the first time i see something like that. And also it points at where the bug is. 

Cant reproduce it. Its random.
