===================================================================
ChangeSet@1.1821, 2004-07-08 00:23:10-05:00, dtor_core@ameritech.net Input: rearrange code in sunzilog so it registers its serio ports only after hardware was fully initialized and with interrupts tuned back on, otherwise it deadlocks. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
