I use PS/2 mouse and keyboard. I've seen there were lots of problems with PS/2 on 2.5-ia64 kernels but I didn't see anyone who had this one. When I say "lots" of interruptions, I mean about 80 times more than the timer ticks !!!! So, one of my processor spend almost all his time dealing with ACPI interruptions . Just to have a look, I've tried to disable ACPI interruptions after the boot. ...and now, the interruptions are reported via one of the serial irq (according to the /proc/interrupts).. if it can help. I had no problems with this interruptions in the 2.5.44 kernel or previous versions. I searched the code to see what had changed between the 2 kernels, but I couldn't find any interesting explanation. BUT I already had problems since the 2.5 kernels(like a lot of people) with my mouse or/and my keyboard (with i8042). So if you have any idea...? Thanks in advance. --------- ** Joel
