I expect this is restricted to the Boxboro-EX Intel platform (possibly
similar) and not to Nehalem CPUs.
If you want to try on newer code you find the latest openSUSE kernel here
(2.6.32-rcX based, even newer than 11.2(2.6.31 based), both should have the
same kdb patch included I posted, I only tried with 2.6.32 SUSE kernel, but
both should be affected):
