Corrupted low memory error on Ubuntu 14.04

[Theron Muller]

I've read the forum post here regarding this error: http://ubuntuforums.org/showthread.php?t=1557604 but it's from 2010 and so am reporting this as a bug.

I'm receiving relatively infrequent messages in the terminal of "Corrupted low memory at ffff88000006598 (6598 phys) = e50000000000" across multiple reboots. The error is especially prevalent when system load is heavy. Memtest through vendor bios checks out as OK.

System boots fine, hangs occassionally, and I have to killall -u from a rescue terminal to have the GUI restart

Can you run a memtest from the GRUB menu? The grub menu can be accessed by holding the SHIFT key after poweron and you see the BIOS loading menu.

Since a couple of weeks I get this low memory corrupted error. Memtest (from Grub) is OK, so I ignored the issue.
But since 2 weeks the poweroff hangs every now and then and I am a bit concerned now.

I am running the same distro also on 2 (64 bit) desktops with no problems whatsooever

Regards

It bugs my PC too (8GiGs of RAM, 5 passes on memtest without an error). But the Corrupted memory shows up after resuming from suspend.
