Serial driver on ixp1200

hi..

  I am using rmk2 patch for arm and ixp1200.2.gz patch from mvista
on a 2.4.18 kernel for ixp1200.

  The serial driver is quite slow(not the baud rate part..), it
seems to be working in blocks.  Transmits few chars, pauses and then
transmits again.

  This was not the case on the linux put up on
netwinder.com(2.3.xx-pre.. kernel).  I can see that the serial driver
underwent a lot of changes between these two versions.
(2.4.18: drivers/serial/serial_ixp1200.c
 2.3....pre..: drivers/char/serial_ixp1200.c)

  Does anybody know the source of the problem?  I would like to fix
it on the 2.4.18 version and send it to the maintainer.

thanx
gopi
