I'm trying to get FreeBSD installed on a Sony VAIO U50, but the install kernel never gets past probing the USB devices and I can't for the life of me work out how to disable USB. In OpenBSD I "boot -c" to bring up the user kernel config and then "disable uhci*" and all is good, but the FreeBSD equivalent eludes me. The ports are all USB2, and the responses I've seen to other people with similar symptoms is to tell the BIOS to not emulate a PS-2 keyboard and mouse - unfortunately my BIOS doesn't have any options along those lines.
I'm PXE-booting the 5.3B4 installer, at the beastie screen I drop to the loader prompt, and then
set hint.uhci.0.disabled=1 set hint.uhci.1.disabled=1 set boot_userconfig=1 boot
but I never see the userconfig screen and the kernel boots the same as if none of those options were set. Here is the tail end of the messages the kernel shows - after the second uhub1 message it just stops (I've left it for 10 minutes or so and there's no progress). Any suggestions would be much appreciated.
