However, the serial seems to still be > responsive. To clarify, this was on top of next-20250120 and reverting the patches that Jon mentioned suspend/resume is fixed for me as well. I do have a local device that I can test on, so if there's any patches you want me to try, or any options to enable to get more information, please let me know. Thanks, Thierry
