I've seen some stability problems with a macronix 98715AEC-C based cards under NetBSD. It sometimes corrupts its receive buffers and the recovery code is not quite right. I suspect the problem here might be the same. Another issue is that the receive buffers must be aligned to 32-bits. I have no idea if the FreeBSD driver does this. The NetBSD one didn't until recently. > > Ok, I'll try asking once more.
