Thanks to Christmas Break I finally found time to dust off my old PPC 
mac.  The last working kernel I had on it was 1.6K installed about this 
time last year.  I built a new GENERIC kernel from last nite's sources 
(1.6ZG) and tired it today.  The USB keyboard doesn't work and all 
access to disk and CD get interrupt timeout errors.  All this works 
with the 1.6K kernel.  The demsg diff output is attached.  Are these 
known problems with -current, or have I stumbled onto something new?

Thanks,
-bob
