In that case I'd expect the problem to show up when doing whatever. So far I
could not find corrupted files on my hard disk, only when writing to tape, and
only with 2.3/2.4.

I once ran into a problem with 32-byte errors appearing in files, and
later, in memory. I eventually traced it to buggy motherboard cache.
(32 bytes is the size of a cache line.) A memory tester might be
something to try (I wrote a simple program that seemed to show the
error better than memtest86; can send it if desired.)
