multiple task hung while adding the vfc disk back to the multipath on my 
powerpc box running linux-next kernel

Test:
$ multipathd -k"remove path sde"
$ multipathd -k"add path sde"

After above command multipathd task hung with continuous call traces on 
console, it requires reboot to stop call traces
