Didn't discover yet, the only "strange" thing is when using <TAB>
autocompleteion in a kterm in kde i get every time a kde crash-bug-report
popup message. however, no kernel messages or whatsoever.

Well it's a fpu patch, and as far as i know i don't use the fpu that much
at the moment but i'll try that.

in the hope finding the usage of fpu-irq:
sjoerd:/usr/src/linux # cat /proc/interrupts
CPU0
0: 13374740 XT-PIC timer
1: 14581 XT-PIC keyboard
2: 0 XT-PIC cascade
9: 238018 XT-PIC usb-uhci, usb-uhci, EMU10K1
10: 601500 XT-PIC ide2, sym53c8xx
11: 87300 XT-PIC eth0
12: 230338 XT-PIC PS/2 Mouse
14: 331764 XT-PIC ide0
15: 39468 XT-PIC ide1
NMI: 0
ERR: 0

But /proc/interrupts shows only those irq's which are currently in use, is
there any way to show usage of currenlty unused interrupts?
