I've noticed some strange/worrying messages in dmesg on my reasonably brand new toshiba z830 laptop.
dmesg shows the following CPU messages (repeated a lot)
Spontaneous reboots (mce: [Hardware Error]: Machine check events logged)
location: ubuntuforums.com - date: November 10, 2014
I have since a while a new desktop system, based on an Intel 4790K and a Gigabyte GA-Z97X-UD3H motherboard. As a lot of people I am dealing with quite high temperatures, reaching 70°C - 80°C under load, with Prime95 small FFT's even 100°C. According to Intel, this shouldn't be a problem.
Since a couple of days I am often using Handbreak to encode some movies. This is causing a processor workload from 90% - 100%. Everything seems to run fine, but after 1h - 2h I'm often getting a spontaneous reboot. I had a look in the system log yesterday evening, and I found this entry
Nov 9 19:12:16 yoda kernel: [ 136.893167] init: plymouth-stop pre-start process (1871) terminated with status 1
Nov 9 19:14:59 yoda kernel: [ 299.821999] mce: [Hardware Error]: Machine check events logged
Next I have installed mcelog and I found this back in the log:
mcelog: failed to prefill DIMM database from DMI data
Hardware event. This is not a software error.

Machine Check Error Ubuntu 14.04 Alpha2
location: ubuntuforums.com - date: February 24, 2014
I wanted to test Ubuntu 14.04 desktop edition in my lemu4, but I got 'Machine Check Error' during boot with the live cd. I used the daily image of 02/21/14 to test the system, although with no success.
Actually my laptop is running 13.04 without issues.
If anyone knows something related to this, I'd appreciate any workaround.
Thanks in advanced.
Hardware error CPU

My computer randomly crashed so I have investigated the problem. As I couldn't have any crashlog or traceback I had to use netconsole. Here is the result: http://paste.ubuntu.com/1464622/
My CPU is E-350. I have tried several kernels (3.2, 3.4, 3.7). I have updated my bios. I have tried to deactivate one of the two cores. It didn't solve the problem.
The bug appears randomly, but it appears quickly after I start an intensive task (in my case it was a ffmpeg conversion). If I don't start such task it could pass days or weeks before the bug occurs.
Bug with 3.7

Diagnosing an AMD Hardware Error
location: ubuntuforums.com - date: June 25, 2012
I just got a new box for a client from Tiger Direct, and it's throwing up errors that seem to be related to the CPU Cache, but it also fails Memtest 86 test 6 (Moving Inversion, random patterns) I'm not really familiar with AMD systems, so I'm hoping someone can help me diagnose what is actually bad: CPU, RAM, or motherboard. It's an AMD FX-8120 in an MSI 760GM-E51 motherboard with two Corsair XMS3 4GB PC10666 DDR3 1333MHZ sticks of RAM, running on 12.04 AMD64.
Here are the logs that show up intermittently in dmesg and syslog:
[Hardware Error]: CPU:2 MC2_STATUS[Over|CE|MiscV|-|-|-|-|CECC]: 0xd8484000010c0176

mce: Hardware error problem
location: linuxquestions.com - date: March 17, 2013
Hello to all,
I have HP 4530s notebook and recently I installed open suse 12.3. I have dual boot with windows 7
I have very strange problem, after approximately 20-30 mins of working on linux machine I'm switched back to console mode with the list of mce Hardware errors something like:
mce Hardware error Processor 2 exception,.... Clot 0 ACPI...some addresses
with last line kernel panic and message that my comp will reboot after 30 sec and it happens almost every time.
I have tried hirens boot 15.2 with memtest86 and HDD diagnost tools but it seems that both of them are fine. I have using external notebook cooling fan so temperature is not a problem (around 45-50 for motherboard and CPU).
Is there some other diagnostic tool to be sure if this is real hardware problem?
linux installs fine but fails at firstboot! is it hardware error?
location: linuxquestions.com - date: February 2, 2007
i have tried installing 4 different distributions but all fail at firstboot. all the distributions report lots of segmentation faults and the errors are different everytime! i thought it must be a RAM problem so i ran memtest86+ from ubuntu 6.06 cd for 4 hrs. passed 9 tests and failed 0. windows runs fine. i'd installed fc6 before on my computer. now i cant install that either. i'm very confused. has anyone faced a similar problem before or knows what could be wrong? How long should i run memtest86 to confirm if my RAM is ok?
note: i have tried SimplyMEPIS 6.0, Ububtu Dapper and Edgy, Fedora Core 6 and OpenSUSE 10.2.
