Yes, I have seen a similar problem.

I have a similar setup to you ( 386 based micro-channel machine with a
WD8003 Ethernet adapter ) and had a similar problem.

The problem turned out to be the Unix driver assumed the 8003 had 8K bytes
of memory when it actually has 16K!

You need modify the file in /etc/conf/pack.d/wd/space.c and change the
defines for WDBOARDSIZE0 from 8192 to 16384. Then rebuild the kernal.

Since making this fix, I have not had any more failures of that type.

A better fix would be for the code to actually use the memory size specified
in /etc/conf/sdevice.d/wd where the beginning and ending shared memory addresses
are specified.

Hope this fixes your problem.
