Screenshot with the errors reported by Memtest86+
Description of problem:
When I boot from the install DVD or USB stick with ROSA Desktop Fresh R1, select "Troubleshooting" at boot launch Memtest86+, Memtest soon starts reporting errors even if memory is OK (see the attached screenshot).
This happens both on real hardware and under QEMU and VirtualBox.
On the systems with 2Gb of RAM it takes no more than 20 minutes (usually - less than 3-4 minutes) for the problem to show up.
When I launch Memtest from the install DVD with Fedora 18 (same version of Memtest, 4.20) on these systems, it shows no errors.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot from ROSA Desktop Fresh R1 install media.
2. Select "Troubleshooting" in the boot menu than choose "Run a memory test".
3. Wait several minutes (perhaps, the more RAM a machine has, the longer one should wait).
Everything is alright with me.

What kind of system have you tried it on? How long did Memtest run?

I tried KDE, Gnome from usb. And one time Gnome in QEMU.
Ok, i can confirm this issue, patched package is on the way.
Hm...and why all works for me? I 20-25% chased test.
I prepared a test image with new memtest
My tests show that test7 no longer shows a lot of errors.

I can confirm that. Memtest from that image did not issue false positives.
The problem has been fixed.
In addition, we now have an automatic regression test for it.
