Do they use intel_idle for the CPU powersaving features? (cat /sys/devices/system/cpu/cpuidle/current_driver) If yes - does booting with intel_idle.max_cstate=0 or intel_idle.max_cstate=3 boot parameter help? It could be related to https://bugzilla.kernel.org/show_bug.cgi?id=21952 somehow, which seems to be an 2.6.35 regression. -- Regards, Richard Schütz
