Hi!
I experience very high cpu loads when using my pcmcia ethernet card
with more than 4Mbit/s. I get the same behaviour for a ep(4) 100MBit
fast ethernet and ne(4) 10MBit ethernet card. Both 16bit pcmcia.
The distribution between interrupt and system load seems to be a bit
strange, also the load goes up very quick after passing the 4MBit
threshold.

any idea how this could be debugged?
