Re: Reproductible kernel crash (2.1.1)

I wonder if this is the same bug that causes my machine (2.2.1 vanilla
i586) to lock-up fatally while accessing floppys (not easily
reproducable). It also died seriously while reading a large file off a
ZIP-100 drive. I get no oops's however. The one thing the floppy lock ups
and the ZIP locks up have in common is that they both were on msdos
filesystems. It has happened while using mcopy too however.
