So, I'm (trying) to run NetBSD 1.6, currently using the 1.6.2 kernel 
that's available from ftp.netbsd.org, to run a diskless VAX 4000/300.  
Every so often, I manage to get the machine into an unusable state, 
where it appears to freeze up an nfs mount, coinciding with this 
console message repeated several times:

ze0: xmit logic died, resetting...

Does anyone have any hits to help me get around this problem?  As the 
4000/300 has a SHAC for its disk controller, I can't easily just put 
disks into the machine to boot off of.  If necessary, I could try a 
QBUS ethernet controller (DEQNA), but I'd prefer to find a solution to 
fix the problems with the on-CPU ethernet controller.

The problem is repeatable, and I think coincides with small-data size 
nfs accesses.  I can, however, use telnet to connect to the machine 
without causing problems from the telnet connection, and other NFS 
mounts on the machine seem to be unaffected when one locks up.  As 
well, this problem occurred starting with the pre-release 1.6 kernel I 
tried, and still happens with a 1.6.2 kernel.

Any help would be greatly appreciated.
