May I suggest running xfs_repair after growing a fs. It think it sets some 
of the neccesary bits right that would otherwise hamper recovery. Although 
i doubt it shoold oops the box.

The first comes from the qlogic driver as it seems, may be wrong about this 
one. Are there later drivers the that available? Do extensive stressing 
make the box oops?

The second, I suspect you need a newer kernel with some NFS fixes. Try the 
CVS tree or the 2.4.7 patch that is one the ftp site.

The third is probably related to the resize. I suggest running repair and 
trying again.
The fourth is probably the nfsdeamon taking a dump in the pool again.
