>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

http://people.freebsd.org/~yongari/sk/if_sk.c
http://people.freebsd.org/~yongari/sk/if_skreg.h

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

State-Changed-Why:  
Submitter doesn't see this on 7.0, and there isn't really 
detail n the PR to investigate further on 6.x.  My suspicion 
is that this was fixed by the interrupt handler critical 
section fixes that went into the tree before 6.3/7.0 were 
released.
