Hello,

I just want to report what happens if a ide controller (or cabling=20
thereof) gets mad. The reiserfs filesystem was not unmountable after=20
that event. Maybe reiserfs should not panic in such an event? (It could=20
keep buffers dirty and allow unclean unmounts so that the gone=20
filesystem could be unlinked from the VFS)
