[-- Attachment #1 --] Hi Adrian! Thanks for looking into this! Yes, it might very well be an ACPI-issue. I noticed the kernel is not completely locked up when I boot 16.0-CURRENT. If I do a verbose boot and press the power button (at the point where the system has stopped booting) another message appears on the console: AcpiOsExecute: task queue not started Every time I press the power button this line gets repeated. I'm not sure if this is helpful in providing info about the hardware in this laptop but I installed 14.0-RELEASE on it so I could run pciconf -l -v, devinfo -r -v and do a verbose boot. If you need more info, just let me know. And if there is anything I can do so you don't have to get one of these laptops let know too. The output of the commands seems a bit much to include in this mail so they're at pastebin: devinfo: https://pastebin.com/6svCYbCF pciconf: https://pastebin.com/N2TJKHLx Kind regards!
