Again, yes. For torture testing, I have a 486/133 and 6x86/P150+ tied
together with a 100BaseTx crossover cable. Both adapters are set for
full-duplex operation. The 6x86 box is also setup as a router between the
fast LAN and the rest of my 10Base network (bunch'o'boxes). Fast SCSI
drives on the 486, fast-wide on the bigger system.

Both machines are running 2.1.57 (with Bill Hawes' nfs patches on the
client) and the user NFS server. I place the kernel source on one machine
and fire off a:

$ make dep ; make clean ; make compressed

If there are any race conditions or network layer problems, you'll
definitely find out quickly <g>.

The latest code seems (knock wood) to be _very_ stable. Now, we can only
hope that Bill works his special magic on the knfs server!
