While trying to figure out some quirky behavior with lvm2, I decided to make sure I wasn't having a memory problem. Since I already had the openSUSE 12.2 KDE LiveCD in the drive, I decided to reboot from that and test my memory. The test resulted in errors. After trying multiple permutations of various memory sticks, I finally put in my Ultimate Boot CD Ultimate Boot CD - Download the UBCD and ran Memtest86+ V4.20 (the same as the openSUSE version) from there. 3 full passes (it takes a long time for a pass on 16 GB) with no errors.
So I went to the website Memtest86+ - Advanced Memory Diagnostic Tool and downloaded the gzipped pre-compiled bootable binary of version 4.20 of Memtest86+ from the source. After decompression, it was exactly the same size (164504 bytes) as the version on UBCD and the files compared without error.
Then I pulled the version from the openSUSE 12.2 KDE LiveCD. It wasn't even the same size (176760 bytes) so I didn't bother with a comparison.
After searching in this forum and seeing an old report of this issue https://forums.opensuse.org/english/...-2-broken.html along with a bugzilla report https://bugzilla.novell.com/show_bug.cgi?id=773569 which claimed the the issue was resolved, I decided to check the i586 & x86_64 variants of the openSUSE 13.1 install DVDs. They also contained memory test programs which claim to be Memtest86+ V4.20, but they were also each 176760 bytes in size. Moreover none of the three files from the different openSUSE media would compare with each other and they all differ at the same location. Here's a typical result:
So-- DO NOT USE the memory test on any openSUSE install media until they REALLY fix this.
