We’re having the same issues with our Dell V3300s.
It makes re-imaging impossible as post deploy it’s meant to reboot a few times to install drivers and jump onto the domain.
Odd thing is that the majority of them work fine, but there are 5 that consistently fail.
Another point of curiosity is that only one of our other office desktops decided to start failing on every boot whereas the rest are fine.
No fixes yet, but I’ll post back if I find one.
