This sounds like a better thing from the user space point of view. I do
not have any insight on what kind of other side effects this might have
so I didn't dare to try that on my piece of (broken) HW. I do not see
the problem all the time and I plan to replace it soon anyway.

Considering that tweaking the power management helps maybe that could be
done automagically after many consecutive failures.

Just my 2c
