I know this is heavily patched, so just mail me for any source-file.

I was using 'wabi' and 'dosemu (xdos)'. The VFS complained about wabi trying
to access the disk drive without a floppy in it about 9 minutes ago:

VFS: Disk change detected on device 02:00
end_request: I/O error, dev 02:00, sector 0
