Yes. My fault. Bug is known, but it was to late to include patch fixing it in 2.6.21 > Yeah, I know there are only a few patches between both, but I would like > to reduce the test cycles to a minimum. Any suggestion where to look > first is welcome therefore, ready-to-apply patches even more... Longhaul ver. 2 support is the reason. First machine that was reported not working is exactly like Your's: Samuel 2 600MHz. Patch reverting changes is queued in cpufreq git. You can find it at http://git.kernel.org/?p=linux/kernel/git/davej/cpufreq.git;a=commitdiff_plain;h=07844252ffd81ec192a62014bada1016c9703765 > Thanks, > Jan Regards Rafał
