I installed both 4.9 and 5.1 ok on my ASUS A7N8X (nvidia chipset) with AMD 2500 cpu. After I cvsup'd to 5.2 a few days ago, the kernel would no longer boot, hanging after: Timecounters tick every 10.000 msec Being new to the cvsup routine, I thought perhaps that I'd made an error in following the notes in UPDATING about installing the kernel and booting that before doing the installworld. So I downloaded the RC2 iso, made a CD and booted from that. It hung on boot in the same place. Booting with verbose logging gives one more line: <snip> procfs registered Timecounter "TSC:" frequency 1837513615 Hz quality 800 Timecounters tick every 10.000 msec lo0: bpf attached Having seen other comments about nvidia and ACPI, I tried booting the CD with acpi disabled - and it worked. I also tried booting my cvsup'd disk image without ACPI and it also worked ok. That leaves me with a system which requires manual interaction to boot. One workaround that seems to work was to rename /boot/kernel/acpi.ko. Not a good solution, as I expect that future cvsup/build cycles will eventually restore the acpi.ko file (and problem). So... the point of the post: 1. The observation of this ACPI problem (might be related to others I've seen mentioned recently). 2. A request for a (cleaner) workaround to booting. E.g., a way to disable acpi by default. thanks for your help! j
