Overall this runs very nicely, but it takes 10+ seconds to resume from suspend, apparently because some issue with the hardrive. The only message I see while resuming is "COMRESET failed (errno=-16)".

I tried that, but the laptop wouldn't suspend. Any ideas? Thanks, Carlos -- kernel-team mailing list kernel-team@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kernel-team
