- Architectures other than i386 are possibly still incomplete, but
  should be rather straight forward (files <arch>/kernel/time.c,
  include/asm-<arch>/{ioctls.h,termios.h}).  See the changes made to
  the common files and for i386 architecture.

- The line discipline code should be revised.

- Some Linux extensions within ``adjtimex()'' (which happens to be
  used as ``ntp_adjtime()'') collided with bits newly introduced by
  the nanokernel.  Therefore the bits had to be moved, breaking binary
  compatibility for the following flags and routines:
  ``ADJ_OFFSET_SINGLESHOT'' (``ADJ_ADJTIME'' now), ``ADJ_TICK'',
  ``ADJ_TICKADJ'', adjtime().  The latter two collide with
  ``STA_NANO'' and ``STA_CLK''.  Fortunately the first one can be
  mapped to the correct function while the last two are quite rarely
  used.

- If compilation fails, please check if ``<sys/timex.h>'' really is
  ``/usr/src/linux/include/timex.h''.  Some glibc-2.1 systems ship
  their own version of ``<sys/timex.h>''.  Reg Clemens <reg@dwf.com>
  confirmed that RedHat 6.0 (and 5.x, too) systems show this bug.

- If the serial port is closed, all special flags are reset; if the
  port is opened again, the interrupt enable register may loose the
  bit for modem status changes, causing high jitter.
