My current 2.6 should work too, the problem is with cpufreq. They seem to have updated the PMU firmware indeed and it no longer accept a protocol violation that was triggered by the cpufreq code (and the sleep code occasionally as well). Actually, I didn't know it was a protocol violation until it started crashing as I don't have protocol specs :) Ben.
