A few things to run are `top', `ps' and `vmstat 1'.
The first two do not show any information out of the ordinary other
than the fact that the load average is 11 while only two rsync
processes are using any CPU at all.
But the load average will be 11 because there are processes stuck in the
kernel somewhere in D state. Have a look for them. They might be things
like pdflush, kswapd, scsi_*, etc. Try getting an Alt+SysRq+T dump of
them as well.
