Hi *

I have one question:
Since Iīm running the new 2.2.1 on my AMD K6-2 300 3Dnow! my xosview
shows me 24 Interrupts instead of the 16 Ints a "normal" i386
compatible System has.

Theese interrups arnīt in my /proc/interrupts.

In the "Kernelsetup menuconfig"--> "Processor type an Features" I
disabled all Options and took "(PPro/6x86MX)" (Ok, I know, this was a
fault but itīs running very well on my machine).

Is it a bug or a feature? Ok, i think itīs very nice to have 24
Interrupts (no more problems with Multimedia hardware :-) but i know
that no PC Hardware is able to be set to INT >15.

Can I use them or is it just a hoax to make beginners asking questions
to the linux-kernel :-) ?

... confused

P.S.
For those who never saw that: a screenshot can be found on
