After updating to linux kernel 6.10.X (all versions from 0 to 5 issue
persists, on both, Ubuntu and SUSE) (btw on Windows everything okay,
so it's not hardware or bios/firmware issue), when disconnecting
charger my laptop starts randomly to freeze output (video/sound
output), making screen blank (black) or reporting SIGV from unknown
service.

This issue could be related to ASUS WMI (MUX chip) or layer for GPU
drivers (btw, issue persists on different version of drivers,
including NOUVEAU/NVIDIA drivers, currently using latest NVIDIA)

Also, it's highly depends on current performance mode of the system
(performance/balanced/power saver)
Power saver -> immediately
Performance -> immediately
Balanced -> from 1 second to ~5 minutes

Also, in balanced mode while charger disconnected, but during this
period when everything works applications randomly crashing (firefox
like example), the same issue observed when using power saver mode
with charger on Also, without charger GDM starts just 50% of the time
when rebooting
