It seems that the second disk is broken and locks up the
channel near the end of the disk.

You could try to remove the drive from the mirror and
run dd(1) on it.  If the dd command also hangs near the
end of the disk, then you should definitely get a new
disk drive.

If the dd command finishes without errors (and displays
the correct number of transfered blocks), then I guess
there must be a bug in gmirror.
