I have a 2020 version Predator Triton 300, i7 10750H and nvidia 2070 max-q, freeze when booting with 5.14.2 kernel just at the line "xhci_hcd: cant change power state from D3Hot to D0". The strange thing is if I have bbswitch and bbswitch-kmp-default installed, any older kernel will freeze when booting at exactly the same line, even 5.13.13. That's when I suspect it's something not related to kernel versions and nvidia. Rolled back the update then updated without bbswitch and bbswitch-kmp-default 5.14.2 boots normally. Didn't tried if 5.14.5 kernel can co-exists with bbswitch and bbswitch-kmp-default.
