Could you test the pro100 adapter with the intel e100 driver with
cpu-saver enabled (insmod e100.o ucode=1) ? (Also playing around with
other parameters like IntDelay, BundleMax and Tx/RxDescriptors might
make a difference). The 'cpu-saver' option should limit the number of
interrupts the nic generates (this might help if the interrupts bring
the machine to halt) (read the e100 driver manual for more information).
