mchehab / rasdaemon

Rasdaemon is a RAS (Reliability, Availability and Serviceability) logging tool. It records memory errors, using the EDAC tracing events. EDAC is a Linux kernel subsystem with handles detection of ECC errors from memory controllers for most chipsets on i386 and x86_64 architectures. EDAC drivers for other architectures like arm also exists.

rasdaemon: ras-mc-ctl --error-count random sorts output #145

Noticed this random sorting behavior of dimm numbers and channel/riser locations for a while but also verified git master version f9cb13b of 2024-02-05 which shows the same behavior. Not sure if its bug or a feature, but this happens on all tested machines (DQ57TM and MacPro 1,1 2,1 3,1) running repository versions 0.68 of debian 12 /ubuntu 23.10 and f9cb13b.

Its independent of the fact labels are used and or registered.
