Kernel logs with resume errors

In the last two weeks the gpu has failed to resume 4 out of 26 suspend/resume
cycles.  Prior to that, the 5.0 kernel (Ubuntu 9.04) did not have this problem.

Here are excerpts from the resume failures.  I am attaching the full kernel
logs from the four crashes.  The first group (gfx_v8_0) has happened three
times, the second group (sdma_v3_0) has happened one time.
