Figured out what made that one node different from the rest: its UEFI network 
boot stack had both PXE and HTTP enabled, while the others were PXE only.
After i added the kernel boot parameters, MAAS started to truncate the HTTP URI 
by a few characters (and now keeps doing that even if the kernel commandline 
options are cleared) which doesnt imapct the PXE clients but does break the 
HTTP ones (this node worked fine before the params were added).

For anyone stuck in this situation, the workaround seems to be to
disable HTTP-based image acquisition in the system's BIOS configuration
menu - PXE only on the IP stack desired will avoid the oddly truncated
HTTP URI which occurs after setting kernel boot parameters.

Title:
  No boot possible - Cannot open root device

Status in MAAS:
  Triaged
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  MaaS cannot boot on my X11DPi-NT and will therefore fail to
  commission. It will instantly fail after grub.

  It will fail to boot saying that is not able to open root device. I
  even tried supplying the squashfs via python on a different port as
  the url is somehow cut off a bit, but to no avail. The python
  webserver doesn't even see any connection try.

  ( custom kernel params: root=squash:http://10.0.33.253:8080/squashfs
  python webserver: python3 -m http.server 8080)

  Steps to reproduce:

  1. Setup maas ;)
  2. Try to commision server
  3. See the kernel and initrd download fly by 
  4. Boom kernel panic

  Hardware:
  Supermicro X11DPi-NT with UEFI http Networkboot enabled
  NIC: Intel X722
