Is my system broken? probably some good reason, maybe –Xen2050 Apr 10 at 23:04 1 @Xen2050 Because the decoding of the message is architecture dependent and it is not always documented by hardware manufacturers. Reasons for an academic to need administrator rights on work computer What danger/code violation is oversized breakers? If you're using an older kernel that does not report the CPUID in the machine check panic you may need to specify the correct CPU (see the manpage ).

The basic model is quite different from mcelog and fully kernel based. See also Wikipedia:Machine_Check_Exception Wikipedia:Machine_check_architecture mcelog Home mcelog References Hardware documentation AMD64 Architecture Programmer's Manual, Volume 2: System Programming BIOS and Kernel Developer's Guide for AMD Athlon™ 64 and AMD Opteron™ Processors This indicates that one of your memory modules has failed.
Still, I advise you to install mcelog to keep track of such events: sudo apt-get install mcelog The events will be logged to /var/log/mcelog. On SUSE systems I see "mcelog: SMTP server problem" messages This comes from a buggy patch that SUSE is applying to their version of mcelog. I inject errors, but nothing happens In many systems where EDAC is running it may intercept all errors before mcelog can see them. Mca: Memory Controller Gen_channelunspecified_err I get "kernel hardware error no human readable mce decoding support on this cpu type" Can you release mcelog?
Now that doesn't mean you'll get an answer of course. –Seth♦ Apr 5 '15 at 15:32 add a comment| 1 Answer 1 active oldest votes up vote 11 down vote accepted Hardware Error Machine Check Events Logged Ubuntu The customer is monitoring /var/log/messages and the above message is subject to surveillance. And I am getting loads of these sorts of notifications saying that there is a Hardware Error and something about mce: OSSEC HIDS Notification. 2015 Apr 04 20:09:22 Received From: Bath-Towel->/var/log/syslog http://www.centos.org/forums/viewtopic.php?t=52582 There's unfortunately no fool proof way for mcelog to detect it. /proc/cpuinfo has a field for APIC IDs so it's possible to translate them back manually.
Linux also has an alternative memory error reporting infrastructure called EDAC. Mcelog: Failed To Prefill Dimm Database From Dmi Data Unless something goes wrong (like some platform mechanism forcing a power switch on reboot) the machine check will then be logged after the reboot.

Although I don't think it is off-topic, you'll probably get more help form Unix & Linux or Server Fault. –Eric Carvalho Apr 4 '15 at 21:50 3 @bodhi.zazen All it my response This is not a software error.

Old Linux kernels reported the CPU APIC ID instead of the Linux visible CPU number. this contact form Meaning of "Sue me" In Fantastic Beasts And Where To Find Them, why are portkeys not used for long-distance travel? If you're doing over clocking or otherwise running your system out of spec: consider to stop doing so now. From mcelog manpage: X86 CPUs report errors detected by the CPU as machine check events (MCEs). Hardware Error Machine Check Events Logged Suse

Once you run mcelog you will not be able to re-run it to see the error, so it's best to output the text to a file so you can further analyze DMI DIMM decoding currently only works on Intel Xeon 55xx, 56xx, E5 (Romley) systems It also requires the DMI BIOS to report the DIMMs in a specific non-standardized format, which may have a peek here We Acted.

Edit: Also, it seems to imply it logged something, where can I find that? mcelog does not start on newer AMD systems anymore AMD stopped supporting mcelog. But it is harmless message, so customer will ignore the above message and check /var/log/mcelog instead.

You can see the current state of the daemon using mcelog --client This daemon accounting is only in memory and not saved to disk. I get "kernel hardware error no human readable mce decoding support on this cpu type" This is pretty much a bug in newer Linux kernels. This likely indicates some problem.

While EDAC supports basic memory error counting and some logging, it does not implement any of the advanced features in mcelog which need user space support. When a corrected or recovered error happens the x86 kernel writes a record describing the MCE into a internal ring buffer available through the /dev/mcelog device.
