This words made me think about upgrading the BIOS. My former version that caused the problem and made me start this thread was F6 from july 2005 and the most recent version is from december 2005[1]. Using this BIOS the former problem is gone! Jens who has go the same motherboard had the same idea and can confirm this "success" with the newer BIOS. That is to say that I can use the keyboard (and mouse) using the ps/2 ports with kernel 2.6.15 and enabled "USB keyboard support" in the BIOS. The keyboard and mouse do also work -- as expected -- conncected to the USB. Thus, I do not know what you kernel developers should do now. You can say to the guys who have the ps/2 problem that they should update their BIOS. But what should they do if their motherboard supplier has not fixed the problem or does not provide BIOS updates at all? And what exactly was the problem? Honestly, I do not want to reflash the BIOS of my motherboard to the older version for later debugging of modified kernel source code since a power blackout during flashing the BIOS could destroy my motherboard...
