[don't know if this got through originally,
 please excuse me if this is duplicate data...]

The zs0a overruns don't happen nearly as frequently under a
GENERIC  1.2.1 kernel as they do under a custom 1.2.1D kernel.

Also, at one point I was accessing the floopy drive and getting
bad block errorson accesses while the zs0a overruns were happening.

I'm wondering:  does NFS service have a severe impact on servicing
of UART interrupts on an IPX?  I do have a di?kless client hanging on
the wire booting from my IPX...

Sorry to flood with questions (though I figure that's what the list is
_for_ when one has problems!), but I'm really trying to understand
what could have happened to the zs driver between 1.2.1 and now.

Would increasing the zs buffer size help any, or is this a hardware
limitation?  Again, I didn't see this until after I upgraded to
1.2.1D-current.
