That is fairly interesting, but may be a red herring.

The code that prints that out basically just runs killall5 -9 with any pids
still running as arguments. After that it will exit, so I suspect the
problem is further down.

There are quite a few scripts between sendsigs and halt..

lrwxrwxrwx 1 root root  18 2010-10-22 13:47 S20sendsigs -> ../init.d/sendsigs
lrwxrwxrwx 1 root root  17 2010-10-22 13:47 S30urandom -> ../init.d/urandom
lrwxrwxrwx 1 root root  22 2010-10-22 13:47 S31umountnfs.sh -> ../init.d/umountnfs.sh
lrwxrwxrwx 1 root root  20 2011-07-14 13:34 S35networking -> ../init.d/networking
lrwxrwxrwx 1 root root  18 2010-10-22 13:47 S40umountfs -> ../init.d/umountfs
lrwxrwxrwx 1 root root  20 2011-07-21 13:55 S48cryptdisks -> ../init.d/cryptdisks
lrwxrwxrwx 1 root root  26 2011-07-21 13:55 S59cryptdisks-early -> ../init.d/cryptdisks-early
lrwxrwxrwx 1 root root  20 2010-10-22 13:47 S60umountroot -> ../init.d/umountroot
lrwxrwxrwx 1 root root  14 2010-10-22 13:47 S90halt -> ../init.d/halt

Would be helpful to mod them all with 'set -x' so we can see what the
last command is before the system fails to shut down.
