What does /var/run/rc.log say about savecore? Please test crash dumps in your configuration before you spend weeks waiting for the symptom to randomly manifest again! Test a similar configuration, say in a VM, if you absolutely cannot take this machine down for a test at a predictable time -- otherwise you'll continue having to take it down at unpredictable times anyway. > Feb 16 14:57:49 legendre /netbsd: [ 2118436.0016171] dumping to dev 18,1 > (offset=253015, size=4162677): Do you log the serial console output? I would be curious to see if anything was printed after that. The last time around, in PR 59024, you shared these two lines of output: > [ 417509.006761] dumping to dev 18,1 (offset=253015, size=4162677): > [ 417509.006761] dump device bad The second line of output is missing in what you just quoted this time, which is curious. I also added a lot of diagnostics in rev. 1.371 that should appear between those two lines and perhaps shed some light on why the dumps are failing (tracked in PR kern/59024 `dump fails on raid0b' <https://gnats.NetBSD.org/59024>). If you're running with 1.370 then you're already on current, so I strongly recommend you update to current with 1.371 _and test crash dumps_.
