Hello, I just filed a bug for the Radeon driver crashing: https://bugzilla.kernel.org/show_bug.cgi?id=217464 It looks similar to this bug (https://bugzilla.kernel.org/show_bug.cgi?id=198669) because they are both locking up the GPU and the page fault address is at the same page offset of 0xffc, which might mean its the same structure member that is being dereferenced (or an underflow), and the call stack is similar. Please let me know if you need any more information. Thanks! -- My Blog: http://www.neilscomputerblog.blogspot.com/ Twitter: @neilsikka
