this may be unrelated, but is this a new box? if not, did it have some kind of strange problems before?
It is a celeron 433MHz on VIA board! The installed OS is new and I had never problems with this machine before.
motivation for these questions: I once suspected a rooted box, since md5 sums of some system binaries changed. It was not rooted, it had a VIA (FIXME-don't remember the number) southbridge. and under heavy io it had single bitflips.
yes. sometimes only on read, and then each read gave different results, sometimes on write too, so it really corupted data.
workaround: switch off DMA access. (no fun on production machines)
I will switch off DMA and wait what happens.
solution: change chipset.
No chance ..
there may be similar hardware problems causing the effects you see.
I don't say VIA boards are bad hardware. they are not. I just report what I experienced.
