udevd should stop after booting completed.
it should not be running continuously.
check if you have to do etc-update
some config files may be waiting.

try to kill udevd and see if cpu load comes down to within 4 %
emerge -DuNav system
it may help.
why udevd continues to run?
try stop udevd should do i think.
once /dev is ready there is a post udevd runs for a littlewhile and stops.
emerge system may help

thnx! for your replay"padoor"
But I can't do emerge system, because computer in another country if some errors in compilation study I can't fix them.


emerge -pvDu system

These are the packages that would be merged, in order:
