Ipmitool not working after upgrade

Hello all! I am currently running a server with an intel SE7501BR2 motherboard. A couple days ago, I decided to upgrade from ubuntu server 12.04 to ubuntu server 14.04 (do-release-upgrade). After doing this, I found that "ipmitool sensor" now yields the following:

Baseboard 1.2V   | na         |            | na    | na        | na        | na        | na        | na        | na

Get SDR 0002 command failed: Unspecified error
Get SDR 0002 command failed: Unspecified error
Get SDR 0002 command failed: Unspecified error

Interestingly enough, "ipmi-sensors" yields the same results as before the upgrade. If you guys had any thoughts on why this is occurring, I'd really like to hear them!
