Hmm, but for me it looks that event-mode also do not power management of my cpu. It runs always with trubo mode. So if there is no workaround available, that would mean that osol2009.06 would not do power management on Toshiba M9 (and possibly others) after first suspend/resume. That would give a lot of upgraders a bad impression against osol2008.11. Maybe there is some quick workaround to set with mdb some value ... ? > > Mark > >> >> 3.
