For the first part I don't have an answer but the softlockups sound 
familiar and the only solution I have found sofar that works reliable is 
to switch back to kernel 3.6.10
I higher kernel level will sometimes work after a reboot but more often 
it will cause softlockups as soon as multipathd is started.
