Comment 16 for bug 1852678

I see what is happening now. On boot all four interfaces are requesting pxelinux.cfg at once using the same IP.

MAAS keeps track of the interface being used for booting as well as the VLAN booting happens on. Because each device is requesting pxelinux.cfg MAAS sets the boot_interface to each device. MAAS sees that the request came in on a VLAN other then what that interface is configured for and updates it. Updating a VLAN causes all IP information to be automatically deleted.

Machines normally request boot information one device at a time which allows MAAS's algorithm to work and not in parallel.

* Why are all interfaces requesting boot information at once?
* Why are all requests coming in using the same IP on 10.245.64.0/21 from 0c:c4:7a:89:f0:67?
* Can you try updating the firmware?
