Hello.
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

->wmtcp is a window-maker applet. 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.
CPU is even the same without it loaded.
