This is _bad_. If I am right, you are the fourth one complaining about
this particular problem... I have the feeling that it is somehow related
to the fact that DMA interrupts are now enabled for the falcon. I thought
the tests Markus performed on his falcon were thorough enough to drop this
savely into the release... I don't know if you already have something working
right now (It's 2 weeks later now), but what I can do is compile a falcon
kernel without DMA interrupts enabled and let you try it - drop me a mail
about it if you want to. This problem is also serious because it might
cause filesystem corruption (at least Dirk reported this) :-(
There is something strange about this problem. I seems to happen on _some_
falcons with _some_ drives. Does somebody know if there are hardware patches
in this area for the falcon?

Yeah, my tape streamer has saved me more than once.... However, there
is another escape. If you have the 1.1 installation floppy's and the
sets, you can install the most important sets. You only have to skip
the first part of the installation and extract by hand (the newer
installation set will also supply an upgrade option). Only programs
you updated that are in the set will be touched.
I think however that the most important thing is getting the (to be) 1.2
kernel to work solidly on your falcon.

Just drop me a mail....
