I don't.  I use quilt, although I occasionally construct a git tree
when there's something in -linux that I need to look at.

The hang happens at the very end of the shutdown sequence, after all
services have been turned off?

IIRC, you said that stracing UML shows a VTALRM-handling loop and that
the UML is consuming all available CPU.  Those two statements are not
consistent, AFIAK, since there should be no busy loops in UML
(although I can imagine bugs which could induce one) and the VTALRM
loop is the sign of the idle loop, which isn't busy.

So, could you confirm all this, and also get a stack trace from the
hang?
