Title:
  Unable to boot 4.15 / 4.18 /5.0 kernel on an Intel Denlow SDP

Status in ubuntu-kernel-tests:
  Invalid
Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Bionic:
  Invalid
Status in linux source package in Cosmic:
  Invalid
Status in linux source package in Disco:
  Invalid

Bug description:
  Node "amaura" cannot be deployed with Bionic / Cosmic / Disco image.

  
  I tried to connect to the IPMI console, there is no output after the prompt:
      Press <F2> to enter setup, <F6> Boot Menu, <F12> Network Boot

  
  The system can be deployed with T/X without any issue, I tried to install the 4.15 HWE kernel on it, but it's not working as well.

  BTW, I can see some RAM related messages probably indicates a hardware issue, not sure if it has something to do with that.
