Architecture. When WHEA detects a machine check exception, it displays the error in a Blue Screen of Death, with the following machine check exception blue screen parameters (which vary, but the first parameter is always 0x0 for a machine check exception):[1] *** STOP: 0x00000124 (0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000) On Linux, a process (such as klogd[2]) writes a message to the how to fix machine check exception kernel log and/or the console screen (usually only to the console when the error is non-recoverable and the machine crashes as a result): CPU 0: Machine Check Exception: 0000000000000004 Bank 2: f200200000000863 Kernel panic: CPU context corrupt The error usually occurs due to failure or overstressing of hardware components where the error cannot be more specifically identified with a different error message.[clarification needed] Diagnosing the error message can be difficult,

although Intel Pentium processors do generate more specific codes which can be decoded by contacting the manufacturer.[citation needed] Most MCEs require a restart of the system before users can continue normal operation, and indicate a long-term problem of a general nature.[citation needed] Contents 1 Problem types 2 Possible causes 3 Decoding MCEs 3.1 Programs to Decode MCEs 4 See also 5 References 6 External links Problem types[edit] Most of these errors relate specifically to the Pentium processor family. Similar errors may occur on other processors and will cause similar problems. Some of the main hardware problems that cause MCEs include: System bus errors: (error communicating between the processor and the motherboard). Memory errors: parity checking detects when a memory error has occurred. Error correction code (ECC) can correct limited memory errors so that processing can continue. Cache errors in the processor. Possible causes[edit] Normal causes for MCE errors include overheating and/or incorrect hardware installation. Specific manually-induced causes include: overclocking (which normally increases heat-output) poorly-fitted heatsink/computer fans (the same problem can happen with excessive dust in the CPU fan) an overloaded internal or external power-supply (fixable by upgrading) Computer software can also cause MCE errors (normally by corrupting data which programs read or write). For example, software performing

It started happening only some time after I bought the notebook, so perhaps some kernel update caused it. When did it start happening to you? –fhucho Sep 26 '14 at 9:35 I'm sorry again, but trying to answer fhucho by commenting further, I get a "you must have 50 reputation for comments".

A fine machine comparable to a Macbook Pro. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought.

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.
