First of all, you should consider your system configuration (namely,
freepages settings) to not to put the system into such out-of-memory
situations.
When it comes to your lock up, both of your cards (epic100 and eepro100) are
suffering from OOM. I would bet that it's epic100 that hangs in such a
situation, because I debugged eepro100 for such cases very carefully, but
haven't heard about somebody doing it for epic100. If your configuration
allows you to test the system with only eepro100 cards (one or two), or with
only epic100, the results would be interesting.
