Well, yes, there are some scripts that touch the fs, but that is IMHO
not the issue here. If it would be I would get the other "unable to
write to locked sector" error.
Instead the fs gets permanently corrupted, i.e. data is written and the
written data is wrong.
Last night I found that the JFFS2 write cache is configured. I will
disable that now and see if that helps - I have the impression that the
fs may contain half-baked stuff after a write. On the other hand, the
JFFS2 write cache is not marked as an experimental feature so I thought
I should be safe...
Well, that like poking with a long pole in the mist, I have to admit.
Very nasty to debug...
If I find something new I'll let you know ;)
But many thanks for your (all of you) help so far!
