I am seeing severe nfs problems between kernels again, 2.4 - > 2.6 -> 2.4 V3 and V4 problems connecting and filesize mismatches between
I'm also seeing stale filehandle problems here in recent kernels.
Setup: x86 or x86-64, TCP, NFSv4 compiled in to both server and client, but not specified in mount options.
This is readily reproducible with rsync -- I just boot to an earlier version of the kernel on the NFS client, and the stale filehandle problems go away.
