The ASUS TP4XE is equipped with a broken Multi-IO chip (UMC 8669F).
Bruce Evans <bde@freebsd.org> investigated all its brokeness in great
detail. One of its bugs combined with a long-lurking bug in the
FreeBSD floppy driver to something that stopped working on the UMC
8669F. (Another bug is that you can't use your onboard UARTs for
UUCP.)
Try this fix. (This is also the version in -stable.)
