Kernel panic after 11.5.2 update

[barmyman]

Hello! I've had 2 random kernel panics after update to 11.5.2. Before this update everything was super stable and smooth. Any help would be appreciated. Info below.

mp_kdp_enter() timed-out on cpu 4, NMI-ing
mp_kdp_enter() NMI pending on cpus: 0 2 4 8 11 12 14
mp_kdp_enter() timed-out during locked wait after NMI;expected 16 acks but received 10 after 17255238 loops in 1800001480 ticks

You can remove these boot args for a start,

-no_compat_check busratio=44 chunklist-security-epoch=0 -chunklist-no-rev2-dev

-no_compt_check is only for forcing macOS to load on an unsupported SMBios. You should use MacPro7,1 or iMacPro1,1

Thanks! Removed unnecessary stuff, but i solved this problem "original mac way" - reseted NVRAM. The problem seems to went away.
