@Sebastian-Roth said in Massive packet loss/NIC issues with new Dell 7070 Ultra in FOG:

Are you sure about that? Firmware version? Exact same hardware? I mean, did you buy those as a batch or several orders?

Updated both laptops to BIO’s version 1.5.1, Exact same SKU, they were ordered along with 4 Optiplex 5070’s (One of those had the same issue, Had to swap the drive to image it) and 2 all in one’s which luckily imaged fine!

About a year ago we placed an order for about 35 All in one Dell PC’s (OptiPlex 5260 AIO) and one of the machines in that batch did the same thing, also in that order were about 15 laptops (Latitude 5490) again, same thing, one machine would have the same behaviour and I’d have to swap drives to image it. Should mention I was using legacy PXE boot back then too, now I’m using UEFI.

@Sebastian-Roth Very true and yes I left the laptop in the exact same port/switch that I ran my live ubuntu test in.

It always seems to fail at any stage once booted to the fog menu, I typically go Deploy Image -> (Username and password) -> Select the image I want to deploy -> Sometimes it fails after I hit enter here, trying to download one of the files to move to where it clears the drive and starts partclone (I believe one is boot.php and bzimage) -> if it doesn’t fail there it typically will move to partclone and then fail while trying to copy each partition image file.

I’ve tried a handful of different kernels with no luck, but the weird thing is I was still able to image a different laptop of the exact same model and config, with the only known difference to me would be the MAC address…

@Sebastian-Roth Funny enough I just tried live booting Ubuntu 18.4.3 on the laptop with the imaging issues and I was able to ping my internal domain controller and the fog server without any packet loss and a very good response time… I would say that rules out hardware?

@Quazz Nope, even when we were ordering Dell PC’s with SATA SSD’s this was an issue.
Currently experiencing the issue with one of our new Latitude 5500 laptops, we ordered two and one imaged fine and the other isn’t able to fully transfer a image. However just in the few hours I’ve been playing around with it I’ve managed to get it to transfer a small amount of blocks by cycling the NIC (Unplugging/Plugging the cable).

It’s a very strange issue, I can’t seem to figure out why it happens exactly, but I suspect it has something to do with either the MAC address burned into the NIC or just the driver that iPXE uses.

I’ve been running into this issue for a few years now, It seems there is always one machine in our order of whatever new Dell PCs that won’t image, The network just stops responding randomly during the bootup phase into Partclone, and if it makes it to partclone it only transfers for about 10-15 seconds and then stops.

Transferring the SSD into the exact same model from the same order will let me image the drive, so it seems like its something within in each Dell PC build that causes this… however I don’t even know where to start troubleshooting it…

My solution has been to just take the drive out of the machine that won’t transfer an image and swap it with one I’ve already imaged, which has been getting increasingly difficult since Dell keeps making the bottom panels of their laptops thinner and thinner…
