I can still get a recent build to lock up regularly on my trips out, for
example by skipping quickly several times in succession (backwards seems
especially problematic). Skipping doesn't always work right either. I also
get at least one 1-2 sec sound dropout in every listening session.

There are also the less critical issues I haven't kept up with, but with the
previous revision of the engine everything worked for me (except
crossfading/beeping) and no lockups.
