Machine Check Exception Fatal (unrecoverable) Mce On Pcpu
LOGS Quote Postby Neeseius » 2015/11/08 02:49:38 I installed mcelog, after it reports machine check exception vmware the exception I cannot find ANYTHING about the error. My computer does not Crash, it had Windows on it for
Mca Error Detected Via Polling
a year with zero problems. I'm trying to move over to Centos 7 with KDE 5 but this is happening. Any idea on why I have this error and yet no logs and machine check exception decoder no problems to speak of?Again I'd like to move to Centos from Windows if I can fix this.Nothing in logsCode: Select all[root@localhost /]# ps -ef | grep mcelog
root 731 1 0 19:25 ? 00:00:00 /usr/sbin/mcelog --ignorenodev --daemon --syslog
[root@localhost /]# mcelog

[root@localhost /]# mcelog --client
[root@localhost /]#
[root@localhost /]# cat /var/log/mcelog
cat: /var/log/mcelog: No such file cmci signaling for patrol scrub ucr errors not supported or directory
Here's the backtrace messageCode: Select all[root@localhost /]# cat /var/tmp/abrt/oops-2015-11-07-19\:30\:54-4010-0/backtrace
The kernel log indicates that hardware errors were detected.
The data was saved by kernel for processing by the mcelog tool.
However, neither /var/log/mcelog nor system log contain mcelog messages.
Most likely reason is that mcelog is not installed or not configured
to be started during boot.
Without this tool running, the binary data saved by kernel
is of limited usefulness.
(You can save this data anyway by running 'cat FILE').
The recommended course of action is to install mcelog.
If another hardware error would occur, a user-readable description
of it will be saved in system log or /var/log/mcelog.
Here's syslogCode: Select allNov 7 19:30:01 localhost systemd: Starting user-0.slice.

I just extracted https://lists.debian.org/debian-user/2016/08/msg00670.html the logs for my machine. Contrary to what the manpage says, I get Uncorrected errors, but no kernel panic. Hardware event.

Favorite Rating: Spurious machine check errors occur on some IBM systems with specific Intel CPUsThis document (7008827) is provided subject to the disclaimer at the end of this document. Environment SUSE Linux Enterprise Server 11 Service Pack 1 Situation Spurious machine check errors can occur on IBM server that use the Intel Xeon E7, Family 6 Model 47 (Westmere EX) Processors: Bladecenter HX5, machine type 7873 System x3850 X5, machine types 7143 and 7191 System x3950 X5, machine types 7143 and 7191 Note that these are errors on the hardware that are correctable by the hardware, so although the errors are reported by SLES, they are not causing any problem. When the error occurs the message "Machine errors logged" is displayed on the console and saved in /var/log/messages. A record of the spurious machine check error is recorded in /var/log/mcelog. Here is an example record: Hardware event. This is not a software error. CPU 0 BANK 6 TIME 1305137281 Wed May 11 14:08:01 2011 MCG status: MCi status: Machine check not valid Corrected error MCA: No Error STATUS 0 MCGSTATUS 0 TIME 1305137281 Wed May 11 14:08:01 2011 MCG status: MCi status: MCi_MISC register valid MCA: BUS Level-3 Generic Generic Other-transaction Request-timeout Error STATUS 8800004020000e0f MCGSTATUS 0 MCGCAP 1000c18 APICID 0 SOCKETID 0 Some fields may vary, but the spurious errors are always reported on BANK 6, and the STATUS is 20000e0f in the lower 32 bits. Resolution Upcoming UEFI updates for these systems plan to include a solution for these spurious machine check errors. Currently the problem can be worked around by disabling the C3/C6 states in the system UEFI settings.
