Error 60 is ETIMEDOUT on SPARC, so it seems that the problem is
basically the same one that you see in your 2.6.32 trace (rpcbind:
server 137.226.167.241 not responding, timed out) except that now it is
a fatal error.

Any idea why the first RPC calls might be failing here? A switch
misconfiguration or something like that perhaps?

Wasn't there a change in the way nfs mount options are handled by the kernel
for nfsroot about the time of 2.6.39? Something about changing from default
udp to tcp maybe?
