[Bug 79980] Random radeonsi crashes

--- Comment #133 from darkbasic <darkbasic at linuxsystems.it> ---
When radeonsi in the right mood (I guess something triggers an higher
instability) then Chrome becomes completely unusable: opening simple urls
without videos is enough to trigger segfaults. The system hangs for a few
seconds and then it keeps working normally until the next segfault.

Kernel is drm-next-3.18, but I had similar behaviour with any kernel >= 3.15

Next week I will be able to provide remote access if needed.
