I was indedd running a slightly older version of the driver. I may have mixed up my kernel build when experimenting with sharing the same build tree over several machines. The driver seems to work fine now, that test no longer crashes it. I also did some iperf tests between two machines with these cards ( the other running linux) and I was getting ~950 MBit /sec between them! Thanks for your help! I'll keep beating on these machines for a few days to come, but will be so glad to get them into productions, they're so fast! :-) cheers, scott
