Yes, lot's of dropped packets during NFS dropout.
This is great, even though I probably won't use the card; My friend has another 9585 and needs an ethernet card for that, and I'll be happy to test it on his behalf.
My machine's working perfectly now... IBM PS/2 9585, 3Com 32529, Adaptec AHA1640, Linux 2.4.1, a 9GB RAID0 array care of the md driver, and ReiserFS running on top of that... filled with MP3's! (just testing...)
Look forward to your patches.
