I install OPNsense 22.7/23.1 to HP stream mini desktop (https://support.hp.com/us-en/document/c04545960), if I set the date with command `date xxxxxx`, it will cause kernel panic.

Comment 3 Yuri 2023-04-11 12:23:17 UTC 
It looks like setting date is triggering NMI, try setting machdep.panic_on_nmi to 1 (H/W error) or 0 (no action).

(In reply to Yuri from comment #3)


sysctl machdep.panic_on_nmi=1
machdep.panic_on_nmi: 255 -> 1
still panic on set date


sysctl machdep.panic_on_nmi=0
machdep.panic_on_nmi: 255 -> 0
no panic / reboot on set date
Comment 5 steely.wing 2023-04-13 02:28:00 UTC 
When

sysctl machdep.panic_on_nmi=0
machdep.panic_on_nmi: 255 -> 0

set date will not kernel panic, but console repeat display

NMI ISA 2c, EISA ff
NMI ISA 3c, EISA ff
NMI ISA 2c, EISA ff
NMI ISA 3c, EISA ff
...

until reboot
