2.6.1-mm4

[Thomas Molina <tmolina@cablespeed.com>]

I issued a reboot command under -mm4 and received the following oops some 
time after the "Sending all processes the TERM signal" message.  This 
message did not make it into syslog.  Following this oops are one 
"sleeping function called from invalid context at 
include/linux/rwsem.h:43" and one "bad: scheduling while atomic!" message.  
Then I get the message "no more processes left in this runlevel", after 
which processing stops.  Nothing further appears to happen, but I can 
still use <SHIFT><PAGE [UP|DOWN]> to scroll screen.

I've typed this in by hand so there may be errors.  This machine is a 
Presario 12XL325 laptop and does not have a serial port to use as a remote 
console.  This oops is reproducable, but does not happen on every reboot.
