Clearly this is a sufficiently common problem that 3COM has had to build a fix for it; it's kind of silly that that program is not built into the configuration program if it's that common. Since 3COM is aware of the problem, I'm betting that some clue to the cause could be had by contacting 3COM. If their BBS is cheaply accessable to you, you might try posting a question about what is causing the corruption, and then let the author of the driver for FreeBSD know what to do about. At the very least, the information about how they fix the CIS would be useful, since breaking it must be doing something similar.
