I can reproduce this by logging with GNOME on wayland, starting up the steam client and then letting the screen blank kick in. Note that starting an actual game is not necessary. Once I try to unblank the screen (keypress or mouse movement), it never does and the machine goes into a soft lockup.
The host is Fedora 35 with a stock kernels. I also see this with earlier v5.15 kernels. I haven't tested anything pre-5.15 though. If I log in with Xorg, I don't see the issue. Video card is:

I'm able to test patches if it helps. Let me know if you want other info as well.
Thanks!

I can reproduce this by logging with GNOME on wayland, starting up the steam client and then letting the screen blank kick in. Note that starting an actual game is not necessary. Once I try to unblank the screen (keypress or mouse movement), it never does and the machine goes into a soft lockup.
The host is Fedora 35 with a stock kernels. I also see this with earlier v5.15 kernels. I haven't tested anything pre-5.15 though. If I log in with Xorg, I don't see the issue. Video card is:

I'm able to test patches if it helps. Let me know if you want other info as well.
Thanks!
Update. I just got the same soft lockup with Xorg as well. Here's the stack trace. The problem looks basically the same. Not sure why it's more easily reproducible under wayland, but it does seem to be:
