Hi Mike,

Super sorry for the ridiculous wait. Your first two emails slipped by my inbox,
which is really silly, given I'm first in the to field...

Thanks for bisecting and finding a free game to reproduce it on. I did not have
luck reproducing this today, but I am on sway and not gnome. While I get gnome
set up, will you be able to test which one of these reverts fixes the hang for
you? Whether just 1/2 is enough, or both 1/2 and 2/2 is required?

I applied them on top of Linus's v6.11-rc6 tag, so hopefully they'll git am
cleanly for you:

1/2:
