I recently purchased a new Dell PowerEdge 2950 as a personal R&D box… hey fuzzing in VMs and testing malware is great and I needed more horsepower. Unfortunately, when I installed CentOS 5.2 (I tried RHEL 5.2 as well) the thing would throw an IERR — specifically e1410 the error bit on the CPU after POST/Grub. I couldn’t figure out what the deal was and Dell was no help. It turned out to be the Radeon device driver. If you don’t boot into X11 or if you replace the radeon driver with generic vesa driver you’re set.
