After installing Wheezy (using FAI, so the setup is essentially unaltered), one of my machines doesn't report memory errors via mcelog anymore. Error messages go to syslog instead:

[Hardware Error]: cache > level: L3/GEN, mem/io: MEM, mem-tx: PRF, part-proc: SRC (no timeout) mcelog setup hasn't changed, actually /etc/mcelog/* is identical to a Squeeze setup that works. Its logfile just stays at zero size. I find it a bit hard to spot important information in the syslog records, in particular whether an ECC error has been corrected or not (and when to take action -> power off the node) Obviously I have missed an important change (perhaps related to edac_* modules??), how can I get back to mcelog?
