Are sysrq-keys enabled? If so, could you catch the tar backtrace during
the lock-up (ALT-SysRq-t)? What was the latest kernel-version that worked?
Can you just try to write some data over NFS? Would it lock if you write 1
byte or 1K or 1M? Does it lock immediately as you start the backup or
after some time (you could start some process in the background
periodically printing some info on the terminal, like vmstat, cat
/proc/interrupts, free, tcpdump on both ends to a file...) Can you try NFS
over TCP? Are other machines, where backup works, also running 2.6,
10/100mbps?
