Unfortunately as this is a production system it's not easy to test other kernels, so this has only been reproduced on a Gentoo-patched 2.6.16. However the Gentoo patches don't modify cpufreq at all and are generally quite minimal. /proc/cpuinfo output is here: http://bugs.gentoo.org/attachment.cgi?id=92370&action=view Does any more info need to be provided? Thanks, Daniel
