Oh, it is indeed. Grmbl. > What kernel version were you using? 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. -Olof
