Oh, it is indeed. Grmbl.

I've reproduced this on a base 2.6.20 g5_defconfig + NFS root and serial
console options on a G5 here.

The steps I have used are:

* Boot with NFS root, default mount options
* mount /dev/sda3 /mnt

... that's all. I have not seen it happen without NFS root, even with
quite active NFS activity. So it seems to be a factor.

I'll continue debugging tomorrow.
