Tell us how recent ... I built my last kernel on last Saturday, and it
works fine (freshly cvsupped sources).  If yours is not more recent than
that, it might be your config or your hardware.

I don't crosspost, so I restricted this one to -smp.  (Now that I've
said that, I'll probably crosspost accidentally on my next reply ...
Mr. Murphy ALWAYS gets the last laugh).

No comment, I don't use the pn device, didn't even know what it was (do 
now).
