We are rolling out new Dell 5570 laptops with M2 ssd's in them to our District Teachers. We are doing a multicast to a group of 24 machines at a time on a single Extreme gig switch in our lab using Zen manual imaging, UEFI, and tntfs. Before the update no problems, after the update, we get 3 computers that drop out of the clone at approx. 75% with the message "loating point exception" at the bottom of the screen ( I assume Floating point exception ). Going through the other screens on the failed machines ALT-F2, ALT-F3, etc. show that on the ALT-F4 screen near the end is the following message:

traps: img[2932] trap divide error ip: 80d04be sp:ffd42080 error:0 in img[8048000+d6000]traps:

We reset the 3 problem computers and re-multicast to them and they have always worked the second time.

We are cloning Win 10 x64 images and before the March update no drops with the exact same equipment now after the March upgrade the errors listed. Also after the drops it takes about 10 minutes of waiting before the master decides it can't contact those machines and the cloning resumes.

Anybody else seeing this issue??
