I can confirm this with the following processor:
vendor_id : GenuineIntel
cpu family : 6
model : 58
model name : Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz

iucode-tool reports the following signature:
iucode-tool: system has processor(s) with signature 0x000306a9

This signature matches with ehoover's (#11) and I had exactly the same error on startup as bryantj247 (#41):

NMI watchdog: Watchdog detected hard LOCKUP on cpu 0
NMI watchdog: Watchdog detected hard LOCKUP on cpu 1
NMI watchdog: Watchdog detected hard LOCKUP on cpu 2
NMI watchdog: Watchdog detected hard LOCKUP on cpu 3

This machine has sssd installed but unsure if it is related. This error happened very early in the bootup process.
