I thought so too, and tried it but got the same crash as you.

However, I'd imagine that if I don't enable CPU idle or the governors,
the board would stay in full power mode always. But this doesn't seem to
be the case.

Then again, I don't see how CPU power management could affect the DSS
directly. So it's probably something like: cpu goes to RET -> something
else is allowed go to lower power state (L3?) -> DSS breaks.
