[debian] State of annoying memory card corruption bug?

I don't think that this behaviour is a real software bug because this
situation shouldn't happen at all. So i don't think that there could be
some patch to really fix this.

And for me these situations you describe nearly never exist. The problem
that the FR hangs occured for me only when the memory usage gets to the
limit of the 128MB. But since i use a 64MB swapfile i never experienced
it again. And my FR never loosed power since i got it. So i'm wondering
what things you do to your FR. ;)
I never lost my partition table and i only use debian for quite some
weeks. Anbd i'm happy that the current OM kernel works with
suspend/resume without problems.
