+The patch below fixes serial console hangs as seen on IP22
+machines. Typically, while booting, the machine hangs for ~1 minute
+displaying "INIT: ", then the same thing happens again when init
+enters in the designated runlevel and finally the getty process on
+ttyS0 hangs indefinitely (though strace'ing it helps).
