Title:
amdgpu resume failure: failed to allocate wb slot
Status in HWE Next:
New
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Bionic:
Fix Released
Bug description:
[Impact]
Systems with video cards using amdgpu driver may fail to resume due to
resource leakage.
[Fix]
73469585510d drm/amdgpu: fix&cleanups for wb_clear
[Test Case]
Verified with fwts for a thounsand runs.
[Regression Risk]
Low. This patch has been included in stable kernel v4.16.y and on, and
it's mostly a trivial bug fix.
