Not the actual resume itself but the feeling > of the machine. the trouble with suspending to ram seems that at reinitialization not all pci quirks are applied the same way like on regular boot. need -ac (alan cox) to discover it recently :) 1 gig of ram and quit a lot is used, here most of the time is spend on writing the image to disk, is much quicker on single user mode, feels like without dma. > It is a Sony PCG-GRX616SP.
