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.
