I've copied kernel from another server (both kernels should be same,
because their .config are same and build environment also was same).
This kernel boot /sbin/runit-init even without paxctl -m... BUT only
in about 50% cases - in other 50% it just hangs like original kernel.

Original kernel looks "stable" - it always boot with paxctl -m and always
hangs without paxctl -m.

As for me, this somehow looks like possible hardware issue... but
everything else works ok (including old kernel and all software on this
server with new kernel).

Only hardware sensor warning detected on this server by HP LO100i is:
    3V CMOS Sense: Lower Non-critical: 2.74 Volts
