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.
