Comment 6 Knud Christiansen 2016-10-01 08:03:37 UTC 
No one cares about this bug ?

Is it really a bug in radeon driver or is it in kernel memory mapping ??

Comment 9 Bjorn Helgaas 2016-10-26 21:38:01 UTC 
Appears to be an upstream kernel bug.  There's a test patch at https://bugzilla.kernel.org/show_bug.cgi?id=175391
