Here's another thing that would be worth testing: could you pin the CPU's frequency to the highest setting (via whatever method of your choice, by selecting the 'performance' cpufreq governor for example). Plus could you do a test with the following additional kernel boot parameter: idle=poll. [both changes would exclude TSC related artifacts.] (This would be for testing only, to narrow down the regression.) Ingo
