  • I suspect that Microsoft just used the wrong bugcheck code. Have you found the problem in your driver?

  • I can confirm that one of the teams at Microsoft used E6 for bugchecks with both DV enabled and disabled. Going forward were working hard to ensure this doesn't occur for new bugchecks and have worked with IHVs and OEMs to look for E6s, so they won’t be changing any existing non-DV bugchecks under E6. Were updating this page below to call out this issue.
