Hello,

if you have an R5k O2 please test the kernel image and userland - both 
are -current from last night -  found here:
ftp://ftp.netbsd.org/pub/NetBSD/misc/macallan/sgimips/
( should work on R10k too but I can't test that )

The difference is that everything ( besides boot64 ) is built with 
- -march=mips3 -mtune=r5k - this saves a lot of space and seems to be 
substantially faster than the official builds which default to 
- -march=mips1
Besides that the kernel contains some changes regarding mace and mec - 
the delay()s in bus.c are gone, instead I put them into if_mec.c since 
mec seems to be the only hardware that actually needs them - not sure 
why though, neither OpenBSD nor Linux seem to need them.
On my machine this is stable so far, mec isn't blazingly fast ( only up 
to 3MB/s ) but I don't get spontaneous resets on heavy network traffic 
either.

have fun
Michael
