we're using debian with our own backported kernels and ceph, works rock
solid.

what you're describing sounds more like hardware issues to me. if you
don't fully "trust"/have confidence in your hardware (and your logs
don't reveal anything), I'd recommend running some burn-in tests
(memtest, cpuburn, etc.) on them for 24 hours/machine to rule out
cpu/ram/etc. issues.
