So on a laptop I have where booting FreeBSD from a usb harddrive results in endless scrolling of text on the console (probably register dumps, hard to tell) until the laptop is turned off, this might be the same issue? I can boot NetBSD and OpenBSD from different partitions on the same usb hardrive, on the same laptop. Is there a known fix or workaround for this issue? (Probably not, but just in case...) -- Regards, Torfinn Ingolfsen, Norway
