Supermicro PDSMI failed to boot on fresh RELENG_7/amd64

[Dmitry Morozovsky]

Colleagues,

3 of 4 times this machine failed to boot, panicing somewhere in late kernel 
initialization phase (before /sbin/init is executed)

I have serial console and KDB enabled, so can do experiments.

Last two crashes:
