Comment 20 for bug 1210393

Troubleshooting steps:

modprobe ipmi_msghandler
modprobe ipmi_devintf
modprobe ipmi_si

Will enable the bmc device parameters to be changed locally and eliminate the write back errors, something I feel the Saucy ephemeral images are not doing.

Secondly, trying to enable link authentication fails to set:
 ipmitool lan set 1 auth ADMIN MD5,PASSWORD

Channel link access still states:
User ID : 4

User Name : admin

Fixed Name : No

Access Available : call-in / callback

Link Authentication : disabled

IPMI Messaging : enabled

Also, setting link access for channel 1 fails:

sudo ipmitool lan set 1 access on
Set Channel Access for channel 1 failed: Unknown (0x83)
