FYI, I did some further research on this. It looks to me that we should recommend Linux v6.6.0 or later, candlelight_fw v2.0 or later, and Klipper v0.12.0 or later. I’ve proposed an update to the Klipper documentation to make this more clear: Improve suggestions on bytes_invalid in CANBUS_Troubleshooting.md by KevinOConnor · Pull Request #6810 · Klipper3d/klipper · GitHub

EDIT: It’s Linux v6.6.0 that is needed for the fix.
