Now I'm on 9-STABLE No usb in kernel, attached mouse pointer. # kldload usb ums ehci # kldload uhci or # kldload uhci usb ums ehci uhci is required for working mouse. Can anyone confirm? Please test few different iterations, as it's probably not easily reproducible. Most times nothing happens, if machine slow downs to crawl/halt , it's on uhci loading stage I suppose. Best if somebody could pin this down on their machine, as I don't have time to debug this now/would have to alter my configuration considerably. best regards, - Jakub Lach -- View this message in context: http://freebsd.1045724.n5.nabble.com/kldload-uhci-lockup-tp5644899p5644899.html Sent from the freebsd-stable mailing list archive at Nabble.com.
