Package: mcelog
Version: 1.0~pre3-72-gcbd4da4-1
Severity: important
Dear Maintainer,
after upgrading from Squeeze to Wheezy, I am no longer informed about memory
ECC errors.
*** Please consider answering these questions, where appropriate ***
* What led up to the situation?
Upgrade/fresh install of Wheezy
* What exactly did you do (or not do) that was effective (or
ineffective)?
I was checking the configuration, and even did a reinstall of the mcelog package
since I had a "logfile=..." line appended to /etc/mcelog/mcelog.conf originally.
* What was the outcome of this action?

but "mcelog --client" doesn't return anything.
Probably related warning when restarting the mcelog daemon:
root@o011:~# grep mcelog /var/log/syslog
Feb 26 13:23:56 o011 mcelog: failed to prefill DIMM database from DMI data
Feb 26 13:32:42 o011 mcelog: failed to prefill DIMM database from DMI data
* What outcome did you expect instead?
The manual pages suggest that "mcelog --client" would read a memory buffer
filled with error messages.
Although memory errors happened, the return of this command is empty.
