I have tried a couple different methods of setup, and both methods produced the 
same results:

Method 1:
1. Successful DHCP install of Ubuntu 14.04.3 onto pole2lp1.
2. Installation forces reboot, and comes back to the login prompt, where I am 
able to enter my chosen UID and log in.
3. Create password for root using sudo passwd root.  (same internal pw)
4. issue reboot command as user after setting root..  (this is not part of my 
instruction set, I just did it because I wanted to verify I could reboot and 
log in as root)
5. The system reboots, and comes back to the login prompt, but does not get 
past the UserID entry. Neither root nor chosen UID worked. It always stayed at 
the user prompt after clearing the screen.
6. I have always had to reinstall to try to work around this. I Always 
reinstall to the same device (mpath0).  Sometimes the reinstall works, but it 
is intermittent. Other users that have seen this may not be using an mpath 
device.

Method 2:  I got these directions from another IBMer when I started in LTE:  
This is a snippet of the 1st few steps.
After  OS installation and login:  1st I created the root pw as before, but 
this time I did not reboot, simply logged off (exit) as 'USER', and then logged 
back in as root.  This worked.  (These directions are for LTE, however in 
reality I installed tools from kte)
1.      Mount the /LTE folder from lte server
>mkdir /LTE
>mount lte:/LTE /LTE
2.      Run setup general to install the useful packages and reboot the machine:
>/LTE/tools/setup general
>init 6

At the time I ran these steps, I did not know that the 'init 6' step
here would reboot the lpar.  When it rebooted the lpar, It came back up
to the same fail as method 1.  Could not get past the prompt for user
ID, even after multiple reboots.

I had to reinstall to get beyond this point again.

The next time I successfully installed (it took multiple attempts) and
was able to set the root PW and log in as root (no lpar reboot) I
skipped the 'init 6' step, and was able to setup and install the LTE
test suites, and successfully get the lpar into the active run.  I have
still not rebooted this lpar since last Friday, and it is still running.
I am fairly certain that if I reboot it, it will hit the fail again.

So, the initial reboot after installation that is forced by the
installer works properly, and returns to the login prompt where I can
log in as the user I just created. At this point, it doesn't matter
whether or not I activate the root user. If I reboot the lpar after the
initial install completes and reboots once I hit this bug. So, I don't
think my method of activating root is the issue, as I have recently
discovered there are a couple of different methods of doing this.

Please let me know if you need any further details. Thanks.
