Re: [gentoo-mips] Re: R5000 o2, kernel

Hi Steve, 
thanks again for the fast response. udev worked real slick.  

I realized my system clock was set to ~1953 (perhaps this has some thing
to do with the mysterious crashes).

I will read up on cross-compiling over the holiday and give my own
kernel build a shot.

-have a good one
Andy
