This one is clearly not rootcaused, but even the reporter isn't sure
what triggered it. It was bisected to that mentioned patch, but even
that bisection result isn't really entirely certain.

So this one will remain pending, I'm afraid.

Something clearly not great in amdgpu suspend/resume land. The reports
are not fully clear, with even the bisection being questionable.

But from the previous cycle reports:

This one isn't questionable, and Len sent me the revert he's been
using on his system for a long time. So I applied it.

Maybe it's related, maybe it's not.
