Actually, that is the problem for this specific case; the firmware isn't installed on that machine. That hasn't been causing failures because GuC submission has been disabled :( It also means DMC is not getting tested, which also goes unnoticed because DMC firmware load failure isn't flagged as an error :(</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
