>> It's simply illegal to free up memory during suspend.
Why? In my understanding, the limit was caused by DMA shutdown.

Subject: AW: [PATCH] drm/amdgpu: only WARN freeing buffers when DMA is unavailable
Big NAK to this! This warning is not related in any way to the hw state.
It's simply illegal to free up memory during suspend.
Reduce waringings, only warn when DMA is unavailable.
