@tbasura You mention multicasting. I have never used clonezilla in a multicast scenario and don’t know how it works. With FOG we use “udp-cast” for this. When you send out a multicast deploy and something goes wrong with the underlaying udp-cast then you’d see a hanging blue partclone screen (though still different as it would not get as far to show the numbers yet but hang with a very plain screen). So my first assumption on multicast playing a role here is probably wrong.
Drivers can’t be an issue either because that’s handled by the Linux kernel.
Will be interesting to see what FOG makes of it. I highly recommend you install the latest dev-branch version instead of the dated last release (1.5.9).
