Can you send us the output > of /proc/interrupts? of which kernel ? I am not at home .. but I have here /proc/interrupts from one 2.6.16 http://bugzilla.kernel.org/attachment.cgi?id=7927&action=view from my bug http://bugzilla.kernel.org/show_bug.cgi?id=6419 Tonight I can attach on bugzilla bug#6419, /proc/interrupts from one kernel 2.6.18 and from one kernel 2.6.19-rc4 BTW: those kernels are for x86_64 arch, I haven't try, yet, i386, but maybe will be my next test.
