Well, there are no known data-loss bugs in 8.2.6, with of course the
operative word being "known" ...

Yeah, I know exactly which message you mean; it was a defense against a
bug that was present for a relatively short time in a few Linux kernel
versions, and could only be exposed on multi-CPU hardware even so.
If you're seeing that and other problems on a BSD kernel then I agree
that hardware issues seem like a likely explanation.  Have you tried
running memtest86 and any other hardware diagnostics you can lay your
hands on?
