I had two lockups in one week, so I reverted back to CFQ. It happened 
while I wasn't using the machine. I came back to find it unresponsive, 
except the mouse cursor still moves. But you can't do anything other 
than move the mouse. Not even SysRq works. Usually I can do the SysRq+ 
REISSUB key sequence to reboot machines that stopped responding, but it 
doesn't do anything in this case. The log contains nothing, meaning 
logging has locked up too.
