udev fails to handle serial device

I only got this bug on this type of computer:

This motherboard has an external serial (problably the same one that the Bios call "Remote Access")

Disabling this on bios doesn't stop it from showing on Ubuntu system, so Ubuntu still tries to configure it, and fails.

Dec 14 08:52:04 pat-228690 init: udevtrigger post-stop process (497) terminated with status 1
Dec 14 08:52:04 pat-228690 udevd[471]: worker [532] unexpectedly returned with status 0x0100
Dec 14 08:52:04 pat-228690 udevd[471]: worker [532] failed while handling '/devices/pci0000:00/0000:00:06.0/0000:02:00.3'

One of the side effects of failing to handle this device, is that cups only starts after udevtrigger has been stopped.
And from system start, to the udevtrigger stopping, there is a delay of 4-5 minutes, where udev tries to configure it, until it fails.
So cups only starts after about 5 minutes of uptime.

root@pat-228690:~# head /etc/init/cups.conf

start on (filesystem
          and (started dbus or runlevel [2345])
          and stopped udevtrigger)
stop on runlevel [016]

I also tried on Xubuntu 11.10, with the same results, only different messages:

A workaround to the delayed cups start, is to modify the file "/etc/init/cups.conf"
Modify these lines:
From this:

start on (filesystem
          and (started dbus or runlevel [2345])
          and stopped udevtrigger)
stop on runlevel [016]

To this:

start on (filesystem
          and (started dbus or runlevel [2345]))
# and stopped udevtrigger)
stop on runlevel [016]
