#1600186 — Linux 4.11: Reported regressions as of Tuesday, 20176-03-14

Hi! Find below my first regression report for Linux 4.11. It lists 9
regressions I'm currently aware of.

As always: Are you aware of any other regressions? Then please let me
know (simply CC regressions@leemhuis.info). And please tell me if there
is anything in the report that shouldn't be there.

Ciao, Thorsten

P.S.: Sorry, I didn't compile any regression reports for 4.10: I 
didn't find time due to various reasons (vacation, a cold, regular 
work, and attending two conferences). Reminder: compiling these reports
has nothing to do with my paid job and I'm doing it in my spare time
just because I think someone should do it.

P.P.S: Dear Gmane mainling list archive webinterface, please come
back soon. I really really miss you. It hurts ever single day.
Don't you miss me, too? ;-)

Should already be mainline as commit 46f401c4297a ("powerpc/pmac: Fix
crash in dma-mapping.h with NULL dma_ops") but didn't make rc2.

I don't see any patch.

Looks like the amdgpu driver has never fully initialized GDS support for
SI family GPUs, and this now triggers the DRM_MM_BUG_ON which was added
to drm_mm_init in 4.11.

AMD folks, should this be addressed by fleshing out SI GDS support, or
by completely disabling GDS initialization for SI?
