I've just tried: * USB and PS/2 keyboards both plugged in, enough key input on the PS/2 keyboard causes a freeze * Just the PS/2 keyboard plugged in, no different. * Just the PS/2 keyboard plugged in, and USB legacy disabled in the BIOS. Same. Is it possible that excessive build optimisations could lead to this? Last time I rebuilt I did so with '-O2 -fno-strict-aliasing' and -march in make.conf. I've been meaning to try with a rebuilt loader with no optimisations... > P.S. -- Why are you slamming keys during the bootup sequence? :-) It's my workstation and I'm usually impatient to get through the bootup sequence quickly. :) Regards, Aragon
