My computer has been always very stable, and after updating my flake today to 49.0, I got two crashes in the span of a couple of hours.
I used Claude code to investigate the crashes, and it has suggested that Hyprland 49.0 is likely the main cause for the crashes.
Here are additional details related to the crash for further investigation. I would suggest rolling back to the previous version of the flake, but I don’t know how widespread this issue is for all users

Pinned Hyprland to commit
29e2e59fdbab8ed2cc23a20e3c6043d5decb5cdc(v0.48.1) in flake.nix:Result: System stability restored, no further crashes observed.
Recommendation
Consider documenting the known instability of Hyprland 0.49.0 with AMD RX 7900 series GPUs until upstream fixes are available. Users with AMD RX 7900 XT/XTX should pin to 0.48.1 for stability.
