Subject: Re: nfs4v stalls transfering files, stalls

Hm, may be the ethernet driver atl1 is the culprit.
I stumpled upon "sendfile() broken with 2.6.26 + Apache 2 ?" and
especially http://marc.info/?l=linux-kernel&m=121619345703525&w=2

So I did "ethtool -K eth0 tso off" and I was able to transfer the file
immediately twice, all three (origin, copy 1 and 2) have identical
md5sum and the transferrate was reasonable at ca. 12MB/s.

Regards, Konsti
