Subject: NFS hangs on Mac port of NetBSD 1.2

I've just brought up the 1.2 distribution that's in the NetBSD-1.2/mac68k area
on ftp.NetBSD.ORG on a Mac IIci. The Mac has an old, old Asante MacCon
Ethernet card in it:
ae0 at nubus0: address 00:00:94:21:c5:63, type MacCon Ethernet, 32k mem.
I see some occasional boot-time glitches with this card:
ae0: length does not match next packet pointer
ae0: len 0000 nlen ff00 start 0c first 00 curr 19 next 00 stop 80
ae0: NIC memory corrupt - invalid packet length 65280
Another time it didn't even configure it at all:
ae0: failed to clear shared memory at 0x7ab7400 - check configuration
But for normal things (rlogin/telnet/ftp/etc.) it seems to work fine, though.
But NFS is another story altogether. I use "amd" with some local AMD maps.
I have my own home directory NFS mounted from my NetBSD/SPARC 1.2 SPARCstation
and pretty much all the other mounts are set up to come from a SPARCserver
1000 running Solaris 2.4.
I have absolutely no trouble at all NFS mounting the SPARCserver mounts from
my NetBSD/SPARC system. But NFS mounts on the Mac simply aren't working. At
first the mounting of my own home directory was working (but inexplicably,
the Mac used an NFS V2 mount and not V3 - why?), but even that's hanging now.
To give a better picture:

The child "amd" process that tries to mount the SPARCserver gets wedged in D
state with the "netio" WCHAN, and attempts to look at my home directory
(the "rlogind" and "rshd" and "ls /home/earle"; dunno where the "find"
processes are getting wedged yet) are wedging with WCHAN "nfsrcv".
The only other thing I can report: If I manually do an NFS mount from my
NetBSD/SPARC system, it works just fine as well. When I do it from the Mac,
I see:

... and that's it. Process stuck on "nfsrcv" WCHAN.
I'm going to try and reboot using "wsize" and "rsize" set to 1K, just for
fun. But in the meantime, any similar experiences or suggestions out there?
