I narrowed down the required timeout, and looks like 25ms is the minimum that works. With 24ms I already started to have failures. So maybe just bump it up by an order of magnitude to 250ms for some safety margin? In any case I think I'll leave the machine running S3 cycles over the weekend with the 25ms timeout just to see if it will eventually fail. -- Ville Syrjälä Intel OTC
