Floppy problems

[Warner Losh <imp@village.org>]

Any idea how to track this one down...

I added a checksum to the kernel to checksum the blocks that were
coming in off the floppy.  The first block checksums correctly, and
comes from track 0, head 0, sector 3.  The second block checksums to
the exact same thing as the first one (this is track 2, head 1, sector
11 or the 101st (1 relative) secort) according to the interrupt
handler, but should checksum to something different according to my
simple checksum progam.

Ideas?
