These same machines, using the same floppies and drives, running kernels older than 2.6.28 work just fine. I googled and found other such reports but no solution. I know better than to just assume it's a kernel bug but it sure looks like it could be so I'm inquiring about it here.

Similar problems on debian testing: see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548434

However, fdformat is ok on Gentoo under 2.6.31 and also on Ubuntu
2.6.32-rc6, so it seems it is not just the kernel version in any
simplistic way.

A git-bisect seems the obvious next step?
