More likely it isn't dropping far enough. > If we convince ourselves that it really does only happen with ohm, and > also only with rtcwake mixed with autowack, and doesn't happen on B2s > in the same configuration, we might find that we have #1835-like > problems when mixing autowack with an ohmd rtcwake immediately after > suspend hits -- we can get a resume happening below the EC's > autowack-delay in that case, which is known to cause problems. I don't believe that it is known to cause problems. test-wackup-ec was designed to flush those problems out at the hardware level, and verifies that the VX855 properly handles resume events while still shutting down. It uses a PWRGD input signal to close the loop with external power supply decay times. wad _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
