All those ??'s are the result of kgdb being unable to look inside
a kernel module. Are you loading NFS as a module? What other modules
are loaded at the time of the panic? Could you try compiling them
statically into the kernel, see if the panic still happens, but with
more debugging information?
G'luck,
Peter
