>Description:
              sk, fxp and ath are giving device timout and stop transmitting
also happens with xl, dc and sis when not running with polling

the exact same hardware setup runs on 5.4-R (SMP +UP) without this errors but on releng_5 SMP the are coming up but not on UP

this I experience on amd64 and i386 with last cvsup up to fev-12

SMP machines are more frequentlu hit, UPs ar standing longer and sometimes they still transmit

no difference if I use ULE or 4BSD

the problem ocurres appearently only if several NICs are installed

I am sure not having cable or hub issues here

the only difference I get with using sk driver from Pyon

he posted on kern/91000 the timeout on SK is gone, on UP and SMP
