I talked to KC and learned updates and results in these two days.Zhou Chun do a good job to help on issue narrow down, now lab can reproduce failure continually with loading custom default. With thin consideration, it’s fine to put below requested tasks aside.From below verified results 3/650 with 80.30.05/greset scenario and 0/700 with 0.41/greset show us the card may disappear after reboot to HP image buildpart on local drive.At factory side there is an on-going task with devcon /r to try to make sure if device disappear again after greset in factory WinPE environment.As the DOE purpose, I believe it worth a try to add cold reboot before SNT parsing for long run automated testing.
