[Linux-cluster] OOPS

[Edward Muller]

Using version 1.01.00 of the cluster software with version 2.01.09 of lvm/clvm 
on an aoe device I get the following error, repeatable under high IO (rsync 
triggers it). When I use the same aoe device with a normal filesystem (i.e. 
not through lvm) the oops does not occur.

Also the OOPS goes away when I disable highmem for my kernel. 

I've been able to create this oops on 2.6.13-gentoo-r5 (yes, I'm using gentoo) 
and vanilla 2.6.14.

If anyone needs any more information please let me know.
