Since the keyboard is responding to characters, you do not need the nmi
watchdog. You should be able to drop into kdb if it is compiled in.
Build with CONFIG_KDB=y, CONFIG_KDB_OFF=n, hit pause on the keyboard or
control-A on the serial console. Documentation/kdb contains the man
pages. Use kdb ps to find which processes are in D state, btp <pid> to
display what it is waiting on.
