The only way I ever got FreeBSD to run on my laptop was by disabling APM,
disabling all the time outs (i.e. hard drive spindown's etc.) - then it would
run OK... If I didn't do that I'd get 'calcru' errors - when the CPU went 'dozy'
(i.e. power saving), or 'wd0: seek errors' when the hard drive span down...

I know other people have gotten varying milage out of the APM stuff, but try the
system with as much of it disabled as you can... ;-) - Have a look at the
-mobile list for more details...

Karl
