looks to me like a classic symptom of a resource conflict.  next time it
happens, check out your irq's:

	$ cat /proc/interrupts

and the base addresses for the hardware:

	$ cat /proc/ioports

make sure each device has its own irq and its own base address.

i know nothing about serial port programming.  i'm curious -- are you running
the data collection program as root?  is it possible to run it as joe user?

can you tell me what kernel you're running and what motherboard/chipset/cpu
you're using?  i try to keep on top of the changelog from kernel to kernel.
