Since upgrading (from 2.4.16) to 2.4.17 I'm getting strange high cpu loads. Always 50% of cpu are used by the system. I made a "make oldconfig" to be sure that I'm using the same config as with 2.4.16. (Also I have disabled "Make CPU Idle calls when idle".) Any ideas what could cause that high CPU ratio ? $ cat /proc/interrupts CPU0 0: 113000 XT-PIC timer 1: 5744 XT-PIC keyboard 2: 0 XT-PIC cascade 8: 1 XT-PIC rtc 11: 6786 XT-PIC usb-uhci, eth0, bttv, es1371 12: 46567 XT-PIC PS/2 Mouse ^^^^ that was lower with 2.4.16 14: 10647 XT-PIC ide0 15: 14 XT-PIC ide1 NMI: 0 LOC: 112960 ^^^^ what's this ?

When I kill it, X takes that amount of CPU. ->lirc_dev is a driver, that taint the kernel, but not made any problems before.
