Dell 1950 EDAC issues

There are a few articles online about EDAC with CentOS 5.8 and higher, but none address the exact issue I was having. Hopefully this will help someone else out in the future.

I have a second Gen Dell 1950 in my studio I use for testing and general services for my office. I’m evaluating oVirt right now and ran into a particular issue. A Kernel module called EDAC is suppose to assist to detecting bad memory on systems. Nice feature, unfortunately, it seems that at least with CentOS 6 and older the Kernel module picks up the baseboard controller incorrectly as bad memory and my system hangs.
Easy fix, after installing CentOS, boot into recovery mode and add the following to this file:


blacklist i5000_edac
blacklist edac_core
blacklist i3200_edac
blacklist radeaon

For me, this allowed CentOS 6.4 x86_64 to boot correctly.

Hope this helps someone.
