> Peter, did you upgrade your kernel? Does the issue is still occurring?

I mean for the wm issue. If it still occurs please filled another bug in DRI,

Regarding GPU hang, assigning to Mesa product (please let me know if I am
mistaken with this GPU Hang).

>From this error dump, hung is happening in render ring batch with active head
at 0xff06f504, with 0x79000002 (3DSTATE_DRAWING_RECTANGLE) as IPEHR.
