Having problems trying booting into Pop Os after todays updates.
I was able to boot into an old kernel. I used mainline to update to 6.4.11. Rebooted and was stuck again.
No longer able to boot into old kernel (makes sense)
Refreshed install. Can now boot. Applied all updates. Back to not booting.
Currently back in after another refresh but I won’t be updating.
AMD 5800X3D 32gb Ram AMD 7900
Looks like Pop just pushed out linux-firmware
20230815
which contains this revert:https://github.com/pop-os/linux-firmware/commit/ae80f1f10609ee6b81f96b98b97aecdb52b5ff5f
It seems like this should fix your issue.
