Re: X11 system lockup with 5.11.0 kernel
Quick update: if this issue was ever fixed, the patch hasn't made it
into the mainline kernel as of 5.13.0. I'm still getting the system
lock-up when X11 starts, and have to hit the reset switch to recover.
For whatever it might be worth, the mainline 5.10.0 kernel continues
to work properly alongside all the user space changes in "sid" that
have happened since late last year.
Respectfully,
