=Comment: #0=================================================
KEITH MANNTHEY <kmannth.com> - 
This represents the patches and code needed to support SMI remediation for the HS22 and x3650m2 and
x3550m2 systems. 

There kernel changes are related to bring the i7core_edac driver and the userspace changes are just
new mapping support. 

Please let me know if anything else is needed.

Upped priority, and fixed Remediation spelling in Summary (sorry, it
was bugging me).

--- Additional comment from lgoncalv on 2009-09-10 22:40:04 EDT ---

added userspace patch to ibm-prtm-1.2-2 and kernel patch to kernel 2.6.24.7-134.el5rt. Enabled these config options:

   EDAC_MCE=y
   EDAC_I7CORE=m

So, consider it applied to MRG RT V1

Verified by code review.  Kernel patch implemented in kernel-rt-2.6.24.7-136 (bz522359-i7core_edac_smi_remediation.patch)

This is bug is cloned from bug #522359 (which contains the kernel part).  This bug tracks the ibm-prtmd user space tool.

Comment 1 Beth Uptagrafft 2009-10-28 20:09:25 UTC
ibm-prtm-1.4-2

File diff between the 1.2-1.src.rpm and 1.4-2.src.rom

Smoke tested ibm-prtm-1.4-2.el5rt against 2.6.24.7-136.el5rt on a ls21 blade, with one tweak.  It loaded fine and the ibm-prtmd started without any issues.

The needed tweak was that the amd64_edac module had to be loaded with ecc_enable_override=1.

Note to IBM:  version reported by ibm-prtmd --version is wrong (it returns 'version 1.1', even though the Makefile got the right version) and the ChangeLog is not changed at all.

Attached is the registered difference between the previous released ibm-prtm-1.2-1 package and the new ibm-prtm-1.4-2.
