Status in The Ubuntu-power-systems project:
  Triaged
Status in debian-installer package in Ubuntu:
  New

Bug description:
  == Comment: #0 - Harish Sriram 
  --Problem Description---
  kernel does not detect interface in Ubuntu, driver missing in kernel

  Contact Information = hasriram at in.ibm.com

  ---Issue observed---
  While installing Ubuntu on a machine with Chelsio card, ubuntu-installer fails to show the interface name - probable cause would be due to missing driver in Ubuntu kernel. 

  Machine Type = Tuleta/Power 8 BML

  ----Additional Info-----
  Installer Shell
  -------------------
  BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3) built-in shell (ash)

  Step to reproduce: Install Ubuntu 18.04 on a BML with Chelsio card
  interface UP.

  ---Expected---
  Kernel to detect the interface.

  ---Actual---
  Installation fails as interface is not detected from the card.
