I think you finally got it this time. Applied this patch against RELENG_6 and it seems to work fine now. I build and installed the kernel, set the loader.conf directives hint.acpi.0.disabled to 0 hint.apic.0.disabled to 0 and reboot on the system... it works well now, thank you ;) >> More precisely, here is a little tab... to be more accurate (i hope): >> >> --------------------------------------- >> USB support | ACPI | APIC | >> ------------------------ >> | on | off | on | off | >> --------------------------------------- >> Did not boot(*)| | XX | | XX | >> --------------------------------------- >> (*) The boot disk seems not be able to be used for the root mount, i.e. >> ufs:/dev/ad0s1a in my case. > If you could get a verbose dmesg for this case using a serial console I'd > be interested in looking at that too. Certainly! The output can be found at: http://www.thilelli.net/~jgabel/store/pub/PR/74989/serial.dmesg.boot-v Note: the kernel used for this boot was the just-previously-patched one. -- -jpeg.
