>Description:
NFS server panics when writing to the NFS exported /home filesystem from an i386 client which is running amd to automount it at /home on the client.
When client boots, /home mounts properly off of the server using amd. However, while I was copying my old home directory from the local disk on the client to the new nfs mounted /home directory using the following command, the nfs server panics and reboots.
from the /tmphome dir...
# find tflorman -depth |cpio -pduvm /home
The system gets through about half of the dotfiles and then the system panics. Thinking that perhaps it was cpio at fault, I tried the following
cp -R /tmphome/tflorman /home
and the system paniced yet again.
I don't have any of the debugging symbols enabled in the kernel so I can't give you much else to go on.
here is the dmesg of the the server...
