Have you tried SysRQ+showTasks? That dumps the kernel stack. You can
convert the numbers to names with ksymoops, or often klogd will convert
them and the result is in /var/log/messages.

What exactly hangs?
Could you run

strace ls /proc/1234
strace cat /proc/1234/maps
strace ls /proc/1234/fd -l

Which syscall hangs?
SMP or UP?
