Basically, there's something strange going on, which _seems_ to be memory
corruption, and seems to correlate reasonable well (but not 100%) with

It's actually unlikely to be preemption itself that is broken: it's much
more likely that some driver or other subsystem is broken, and preempt is
just better at triggering it by making some race conditions much easier to
see due to bigger windows for them to happen.

The problem is finding enough of a pattern to the reports to make sense of
what seems to be the common thread. A lot of people use preemption without
any trouble.
