Her'es the error, it only happens right after I boot up and never happens again until another reboot:Hardware event. All sticks are good.

dobbi19th June 2014, 05:16 AMSorry, does this shows anything? # mcelog --client source: According to the man pages a certain amount of errors is to be expected only when a From what I can tell, this looks to be a false positive error generated by memtest86.

In my directory /sys/devices/system/machinecheck there are machinecheck0-7(one for each logical cpu of my system I presume). Or can anyone give me some hints on how to analyse the information? Thank you for all your help! In my directory /sys/devices/system/machinecheckthere are machinecheck0-7(one for each logical cpu of my system Ipresume).

All ram stick showed no problems, tested on another machine without issues as well.However,after further investigation I found something strange is happening. My rule of thumb for firmware-related problems is that the vendor tools are usually the most accurate, but the least usable. This is a hardware problem, those messages come directly from the processor not the software part, change it, find a firmware, contact the manufacturer. For memory page errors the threshold is 10 events over 24 hours. (I'm not really sure where this number comes from but it's probably a reasonable reference point).

Work on your spelling a bit and you'll find a good community here.Your problem relates to the CPU getting bad data from cache which was detected by ECC.This is ALMOST ALWAYS The POST info displayed that both DIMM B1 & B2 are running at DDR1333 with ECC enabled.ram in channel one dimms - A1 & A2 running fine same ram in channel Having received the MCE log always for cpu 0, I went to look inside dir machinecheck0 and I found bank0-5ctl.

Otherwise it seems like you'd run into memory coherency problems. Any other ideas on how to determine what piece of hardware BANK 5 and BANK 6 refer to? When a corrected error happens the x86 kernel writes a record describing the MCE into a internal ring buffer available through the /dev/mcelog device mcelog retrieves errors from /dev/mcelog, decodes them

I've yet to experience any hangs or crashes as a result of these errors. But when I use this UC memory to do complex work (such as make kernel), my system crashes. Zero problems anywhere, I even ran Inte's Processor diagnostic tool in linux (fedora 15) and Windows form. The more generic open source tools are easier to work with, but may not provide enough information to show exactly what's going on.

The time now is 04:46 AM. Having received the MCE log always for cpu 0, I went to lookinside dir machinecheck0 and I found bank0-5ctl. Pat

Top Log in to post comments le g. Erratum or not?I noticed something else, which though may be due to my inexperiencewith mce messages.

Could this in fact be a software issue or false possitive? Log of MCEs(They all happended once for each reboot): "Boot 0" MCE 0 HARDWARE ERROR. Yes, I tried setting memory type to UC/UC- and the program runs well. I got no error when i am running memtest86+.

When you do a write to WB memory, the line sits in the cache for some time until it gets kicked out for some reason. Only when I set both PAT and MTRR to WB does the kernel crash. Try memtest86+, and see if the error persists, then it's likely that you have a faulty processor. There is one set of mappings that can be made to work on at least some x86-64 processors, and it is based on mapping the MMIO space *twice*, with one mapping

I'll do the memtest but I also fear as stated previously this might be a CPU cache problem. This is not a software error.MCE 1Hardware event. You can even check for those with a camera they show up as bright spots in any camera image because the high energy particles overwhelm the image sensors.

I was able to set up my MMIO range with an MTRR of "Write-Protect" using the /proc/mtrr interface:       echo "base=0xd0000000 size=0x08000000 type=write-protect" >/proc/mtrrand "cat /proc/mtrr" confirmed that this set up a Does that count start from 1? I've also encountered the error when using a SSD. There have been no resolution except for Microsoft telling you to upgrade your PC to the latest BIOS.A machine check error is an error in the processor that is detected by

ps: But everytime I see the word bank I am sure it is the memory sticks. Basically the SRAM cells of your processor's caches are being heated so greatly that they are losing state.Check the CPU temperature. I have a pci device registered with some physical memory addresses. There are a number of ways that a processor should be able to invalidate a cached MMIO line.  Not all of these will work on all implementations!  Cached copies of MMIO
