Sorry to go off the list. In 2006 I was doing sysadmin work for the Nuclear Energy Institute. NEI performed a hardware refresh, and supplied ~50 employees with new Dell laptops. I don't recall the model, but they had integrated Intel wifi. The laptops would connect via wifi, and disconnect after about 10 minutes. Dell support told us we needed to update the BiOS or UEFI. It fixed the problem. About 6 months ago, I bought a used Intel NUC model NUC5PPYB. It was running Fedora 39 at the time. A `sudo reboot && exit` over SSH would cause the machine to hang on shutdown. I had to walk over to the machine and cycle the power. The NUC had UEFI from 2015. I updated to the 2022 version of the UEFI (version PYBSWCEL.86A.0081.2022.0823.1419), and the hang on reboot was fixed. Apparently there was some problem around ACPI. Jeff
