Spinlock Lock after Firmware Update

[Watcher]

Was running nextCloudPi on Armbian 21.02.1 stable, headless. Board: v3 w/ 4G
No issue for over a couple of months, 5A power, htop would indicate temps in the 36-45 range.

Today (2021-02-09) Installed the Armbian configuration utility and conducted an update on the board firmware.
Currently unable to complete a boot of the OS.
It appears to be having issues sometime after starting the Network manager.

A failure is flagged when attempting to start the network interfaces.

After either the starting of the Network Manager or the Setup of the zram based device zram2 messages similar to the following are generated:
BUG: spinlock suspected on CPU#0, armbian-hardwar/667
BUG: spinlock suspected on CPU#2, ln/670
    lock: 0xffffffc0fec1c0, .magic: dead4ead, .owner: <none/-1, . .owner_cpu: -1
BUG: spinlock suspected on CPU#3, ln/679
    lock: 0xffffffc0fec1c0, .magic: dead4ead, .owner: <none/-1, . .owner_cpu: -1
    lock: 0xffffffc0fec1c0, .magic: dead4ead, .owner: <none/-1, . .owner_cpu: -1
BUG: spinlock suspected on CPU#1, migration/1/12
    lock: 0xffffffc0fec1c0, .magic: dead4ead, .owner: <none/-1, . .owner_cpu: -1

Then it locks up...

Any suggestion or guidance would be appreciated.
