If this is with the current kernels, there's not much to do about
it--it's something in one of the MRG calls that wedging.  We certainly
don't intentionally wedge...

This certainly shouldn't panic the system.  IMO, although if it's
something like a loss of CD, the proper cable would do the trick to
fix it.

"Go for it!"
Actually, I think the current plan is to integrate the raw ADB code
from John Wittkoski when it's ready, so if you're going to work on it,
I recommend working on that code instead of the MRG.
