If you can use the other ports, it may be that this port #5 fails to
calibrate, or is toast. You need to look at dmesg output to see if such
is the case. If it is a calibrating issue, check the archives for the
compile options to work around it.

The archives will also tell you that it is a bad thing to have the
digium cards share interrupts with anything, and may cause trouble like
line noise. If you remove serial support and/or usb support from your
kernel, you should be able to free up a dedicate IRQ for the X100P's now
sharing IRQ 11. Note that many motherboards have pci-slot 1 and 5 share
irq allways. If this is the case with your equipment, I have no solution
for you to get dedicated IRQ's on all digium boards.

Note that the IRQ problem MAY be the cause of your problem, I'd first
investigate the problem of the one port on the TDM40P, as I don't recall
ever seeing a message indicating that IRQ overlap would cause only one
of 4 port of a TDM40P to fail.
