We don't have the panic message (no console access) but we are trying to 
create an usable core dump.

When we used a MP kernel gdb complained about "Cannot access memory at 
address 0xffff80005bfca6c0" so right now we have booted on one CPU and 
are trying to produce a panic, but so far it is stable. Before when we 
copied files over NFS it paniced several times a few GB into the copy 
but now it runs fine, perhaps this has to do with the MP-kernel?
