Did you try on a recent Intel processor machine?
Both machines I tried had rather recent Intel cpus.

cat /proc/interrupts >/tmp/irqs;sleep 1;cat /proc/interrupts >>/tmp/irqs
uname -r
3.10.0-rc2-3.g17364b5-default
I also tried the latest:
3.10.0-rc3-119-ga93cb29-1-vanilla
without any SUSE patches and it still shows the issue.
Find also attached /proc/cpuinfo and /proc/config.gz
