After displaying these lines also as 
Setting hostuuid: dfd33398-e9ed-11de-92f6-0013d4d9c93b.
Setting hostid: 0x9ca0935d.
Entropy harvesting: interrupts ethernet point_to_point kickstart

system hangs and stop booting on exactly 30 minutes! After 30 minutes timeout 
it continue boot as usual.

More ealry version displays here "AutoSense failed", after recomplie kernel it 
does not, but still hangs on 30 min.

(do not offer to throw out this reader - it works on 6.x, 7.x. Of 
course "conditionally" - at 6.x it can hang up box, when their uptime was 3-4 
days, but works and DO NOT STOP boot!)
