Machine Check Exception !

Machine Check Exception !

[Legend W.]

Hello,

I get the following message under 2.4.21 from RedHat:

CPU 3: Machine Check Exception: 0000000000000004
<Bank 0: b20000001040080f

and the box is dead.

When i use parsemce, it said:
Status: (4) Machine Check in progress.
Restart IP invalid.
parsebank(0): b20000001040080f @ 3
        External tag parity error
        CPU state corrupt. Restart not possible
        Error enabled in control register
        Error not corrected.
        Bus and interconnect error
        Participation: Local processor originated request
        Timeout: Request did not timeout
        Request: Generic error
        Transaction type : Invalid
        Memory/IO : Other

Can anybody please enlighten me what this means or what a possible
problem behind might be?

Thank you in advance

PS: my box has dual Xeon 2.8G CPU

if you want to make your machine run any way use "nomce" at boot
prompt against your respective grub entry.

This is a terrible idea.  MCEs indicate some kind of hardware problem,
it would be idiotic to just ignore that.

Figure out the hardware problem and fix it (bad RAM, overheating, poorly
seated card, etc).

Executive summary - your hardware is broken. In this case its reporting
a parity error on external tag bits - presumably cache bits. "Contact
your system vendor for advice" as they say 8)

[Dana Lacoste]

I used to get these all the time as well (with a very
similar hardware setup) and although I have never
identified exactly what was wrong (still using 2.2.x)
I don't get them any more after doing this :
1 - switched from IDE to SCSI
2 - changed RAM vendors (yes, this was unpleasant)
and, most significantly :
3 - made sure the BIOS had the correct microcode update
    for the CPU.  the one it had was out of date, and
    changing to the latest from Intel solved a LOT of
    instability issues....

Flaky RAM tends to be one of the more popular triggers
of these exceptions, so (2) above was more than likely your
cause as opposed to (3). (1) seems incredibly unlikely
unless it had adverse change on power drain.

Machine Check Exception ?

[Stephan von Krawczynski]

Hello,

I get the following message under 2.2.19:

Message from syslogd@diehard at Thu Jan 24 14:44:49 2002 ...
diehard kernel: CPU 0: Machine Check Exception: 0000000000000004

and the box is dead.
Can anybody please enlighten me what this means or what a possible
problem behind might be?

Thank you in advance
Stephan

Whats the mobo? What do you mean the box is dead? Dead or deadly stalled on
boot?

I will answer later, it is remote, I have to check out. It is UP, btw.

It boots and runs for quite a while (weeks), then suddenly freezes and 
shows this message.
It does not happen often, but very rarely.
Has the number any meaning, or is it a goof?

Stephan

 This number alone doesn't really tell anything.
 There should be an extra line in the log / on the console,
 which contains two more 64bit numbers. Putting these into
 http://www.codemonkey.org.uk/cruft/parsemce.c will decode
 them and give you more idea hopefully over whats wrong.
 (I really should make that tool a little friendlier ..
  I'll do it soon)

Hi,

I had the same error sometimes, during heavy load (compiling).
I replaced a memory module by another and it didn't crash anymore,
until now at least ;)

 Typically a hardware problem. Some older systems generate them
 spuriously though, which is why we have a "nomce" boot option.

My system here is a P3 800 Coppermine with Infineon RAM.
After removing that module it didn't occur. Linux 2.4.17.
