How do you manage it at a large fleet of hosts? Do you have rasdaemon logging always and how do you correlate with kernel crashes? At Meta, we have an a "clues" tag for each crash, and one of the tags is Machine Check Exception (MCE), which is parsed from dmesg right now (with the regexp I shared earlier). My plan with this patch is to have a counter for hardware errors that would be exposed to the crashdump. So, post-morten analyzes tooling can easily query if there are hardware errors and query RAS information in the right databases, in case it seems a smoking gun. Do you have any experience with this type of automatic correlation? Thanks for your insights, --breno
