Here are the corresponding files (using RELENG_5 at this time): http://www.thilelli.net/~jgabel/store/pub/PR/74989/ > USB works for you so long as you have APIC disabled, both with ACPI > enabled and disabled correct?

More precisely, here is a little tab... to be more accurate (i hope): --------------------------------------- USB support | ACPI | APIC | ------------------------ | on | off | on | off | --------------------------------------- KO! | XX | | XX | | --------------------------------------- ok | XX | | | XX | --------------------------------------- ok | | XX | XX | | --------------------------------------- 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. Note: this box currently run the RELENG_6 branch, build at Wed Nov 30 07:12:41 CET 2005. -- -jpeg.
