Random0Munky,
Would you do me a favor and run this command to identify which IPMI you are using? Either SLES or OMSA.
zypper wp ipmi_si.ko
After that we will want to try switching to the other, whichever that would be.
Let me know what you find out.

Good morning Chris,
Thanks for the reply:
Here's the output I received while doing entering in that command:
# zypper wp ipmi_si.ko
Loading repository data...
Reading installed packages...
No providers of 'ipmi_si.ko' found.
/lib/modules/3.0.42-0.7-default/kernel/drivers/char/ipmi# ls
ipmi_devintf.ko ipmi_msghandler.ko ipmi_poweroff.ko ipmi_si.ko ipmi_watchdog.ko

I have received a reply from the SUSE forums with this. Is there anything to shed some light on:
Firstly for others watching this thread please note this issue has also
been posted to the Dell Community Support Forums @
en.community.dell.com/.../20379839.aspx
Does the server boot through UEFI? Dell have an Installation Instructions
and Important Information document for PowerEdge Systems running SUSE Linux
Enterprise Server 11[1] and page 14 includes the following issue and
resolution:
--begin--
IPMI May Not Start On Systems That Boot Through UEFI
Description
The IPMI kernel modules might fail to load on systems that boot through
UEFI. As a consequence, services that depend on IPMI may be affected.
Work around
To work around this issue, add the following line to/etc/modprobe.conf
before starting the IPMI service:
options ipmi_si type="kcs" ports="0xca8" regspacings="4"
A fix for this issue will be available in a future SUSE Linux Enterprise
Server 11 kernel update.
Cause
This is caused due to a kernel bug that sets the IPMI driver to use the
Block Transfer (BT) interface instead of the KCS interface.
---end---
Of course it's possible that the above issue has been fixed in a later
version of the kernel and is not your particular issue if using UEFI.
HTH.
