XPS 8910 BIOS Problem

I just took delivery on an XPS 8910 desktop, i7, 16GB, 750Ti, 2T disk.  Beautiful machine except for a BIOS bug that caused me to reinstalled Windows 10 Pro twice.  I'm using Windows version 10.0.14393 and BIOS version 1.0.9/9/1/2016. 

By default, the machine will not wake up from sleep on mouse or keyboard input.  I went into the BIOS Advanced section and enabled the "USB wake up S3" option.  BOOM.  Saving the BIOS caused the machine to fail on every reboot attempt with the BAD_SYSTEM_CONFIG_INFO error.  I tried many recovery strategies, including messing around with bcdedit, but reinstalling the OS turned out to be the path of least resistance for me.

The first time I reinstalled Windows with the BIOS factory settings.  Everything worked as it did originally; a second attempt to change the BIOS setting caused the same problem.  I reinstalled Windows again, this time with the "USB wake up S3" option enabled before reinstalling.  Now everything works and I can even wake up the sleeping machine with mouse or keyboard input.

I would formally report this bug to Dell, but the support page process was too rigid and time consuming.  Hey Dell, how about a simple "express" form that allows one to submit their Service Tag and a problem description after logging in on their Dell account?

Until that happens, I hope my experience helps others avoid a long, treacherous evening.
