@Mark: I don't think it can be alignement errors, because such errors
would appear on all NSLU2 running Debian, while I seem to be the only
one to have such problems. Thank you anyway for the suggestion.
It would apply to everybody running NSLU2s with /that/ version of
Debian, which I suspect is a very small number of people. I'd suggest
reverting to Lenny, exercising the unit thoroughly (e.g. do a kernel
build) and then basing your opinion of its reliability on what you see.
You should always check the power supply of the nslu2, I had mor than one
that failed softly, exposing various strange errors.
I see. What should I test? that the nominal voltage is proper and
stable? However, if that was the case, the machine would fail
erratically, I believe, while it appears to fail quite deterministically
(upon an apt-get upgrade, for example).
Basic parameters are DC voltage on load, and AC ripple on load. You'll
probably need fairly decent test equipment to see the switching frequency.
