OK, good to know. Does this problem occur with S2D?
What is the very first command that triggers this timeout error?
I'm wondering what is the difference between them -- according to your
report, reloading the module fixes the problem. But, the resume
callback is almost identical with the re-initiailzation.
Perhaps it's something to do with the power-state management.
What about the patch below?
