Bug#596528: xhci in 2.6.32.y


We just got this bug report <http://bugs.debian.org/596528> on the
Debian kernel based on 2.6.32, which looks like it might be addressed by
a subsequent change.

Is xhci really stable in 2.6.32.y?  I see there have been a number of
bug fixes after 2.6.32, but these have not:

(There may be other important fixes; I didn't look too closely.)

Should some of these go into 2.6.32.y?
