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)
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.
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 19:14:59 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.

Forgive me if this is already posted somewhere, and if so if someone could post a URL or direct me in a direction to solve my problem.
Having said that, My install of xUbuntu has found a few "hiccups" things were running smoothly then recently, the system "blacks out" to what I can describe as a terminal shell with some wording, then resets to the gui login screen. I would like to fix this rather than do a complete install of xUbuntu again. so what I'm looking for is if there is somewhere within my system that logs errors or something of that sort that will help to describe what exactly is going on, if there is a script or something that is causing this "reboot" cycle.
This might be a no brainer to some but these "hiccups" seem to have begun once I installed VirtualBox, I don't know why that would or could cause a problem but some may/will know more than I.
Error: cannot read the Linux header. Error: you need to load the kernel first

I'm having a few problems getting my system to boot after upgrading to 11.04.
On trying to boot the 2.6.38-8-generic kernel, the message
error: cannot read the Linux header
error: you need to load the kernel first
displays and then returns to the GRUB menu.
This problem actually first arose when I upgraded from 9.10 to 10.04 a couple of weeks ago, however I found I was able to boot by loading a selecting a previous kernel version (126.96.36.199 was the latest version I could successful boot from) and as I was a bit busy with exams at the time I decided to leave it be temporarily as I at least had a functioning system.
I upgraded from 10.04 to 10.10 and then finally to 11.04 today. The original problem persisted on the upgrade to 10.10 however I was at that point still able to boot using the older kernel version. On the restart after the upgrade to 11.04 however, the system now freezes when trying to boot from 188.8.131.52 or previous versions (the splash screen shows an

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.

hi, a couple of my friends are going to buy new computers - either a desktop or laptop. both will probably buy something Linux compatible if they can get it easily, after my going on about it so much but, it doesn't seem that easy to just buy something you know will run Linux.
what's the easiest way to make sure something you are going to buy will run Linux? are there any good sites, or lists of pre-built desktops which are best to get? if i knew it would work and it was easy, i wouldn't mind putting something together, as i'll probably set them up anyway. BTW, i live in the UK. thanks.
