3.2-release NFS client to Linux NFS server: mount hangs.

I've been wrestling with this for a day now.

OpenBSD 3.2-release box is a client to a Linux 2.4.19 NFS server. Mounting the server from a Linux client works. Also, the Linux box is serving NIS to the OpenBSD box just fine. Here're some details:

openbsd# showmount -e linux
Exports list on linux:

/home                              10.1.1.0/24 

openbsd# pfctl -d     # no scrub rules or anything.

openbsd# mount linux:/home /mnt

At this point mount hangs and may or may not return the following error:
nfs server linux:/home: not responding

If I break the mount process, the mount_nfs process stays hung and will not die.

Am I completely missing something? Am I a fucking idiot? Any suggestions/comments/flames appreciated.

dmesg for the hell of it:
