You have a block size of 32K, I'll bet it's 'Bad nfs svc reply' in
nfs_syscalls.c. This is triggered when the READDIRPLUS op generates
an oversized reply and it triggers the sanity check.
Change it to 16K and I think it'll work. Otherwise change the panic to a
printf(), but that is sweeping the problem under the carpet and might just
give the client indigestion. It does stop the server crashing though.
