Sounds to me as if you haven't any Subnet Manager (OpenSM or managed 
switch) running.
$sminfo
sminfo: sm lid 2 sm guid 0x8f1040041254a, activity count 751941 priority 
3 state 3 SMINFO_MASTER
$ sminfo -P 2
ibwarn: [17975] mad_rpc: _do_madrpc failed; dport (Lid 3945)
sminfo: iberror: failed: query

(we don't have any SM on the subnet connected to port 2)

Your reboot might have started OpenSM. Thus making it works
