Just discovered (and verified with latest build on current.freebsd.org) that the following will panic the new GEOM fdc driver in 6.0-current: # dd if=/dev/fd0 bs=55 panic: wrong length 55 for sectorsize 512 And further checking, discovered that ALL disk devices will cause a panic: dd if=/dev/ad0 bs=1234 panic: wrong length 1234 for sectorsize 512 Perhaps this is geom's way of complaining? Seems a rather radical way to handle non-matching-blocksize reads of disk devices. A simple programming error reading a disk dev node will panic the machine. -scott
