Comment 216 for bug 585765

I spent about 3 month with my machine in single user recovery boot up which worked fine.
As soon as I go past init S into init 2,3,4,5 system hangs. Total system lock up.
If i tried to go back to init S after $ telinit 2,3,4,5 or $ init 2,3,4,5. it would still hang.
It would consistintly freeze or restart at about 30 after xserver started. Whether I logged in or not.
Nothing of interest in the log files. no errors, just normal messages.

I have not tried to ssh into the system.

I spent the last 2 days going through the /etc/init.d/ and /etc/rc*.d/ to try and figure out why this was limited to runlevel above single user.
runlevel 2 through 5 are the same. Default in Ubuntu is init 2
$who -r # will show you what init level your are currently in.

I found the offending script to be in
$ file /etc/rc2.d/S99ondemand
/etc/rc2.d/S99ondemand: symbolic link to `../init.d/ondemand'

when i renamed it
$cd /etc/init.d/
$mv ondemand bk.ondemand

Boot back into normal standard ubuntu every thing is going fine now
$uptime
 14:17:43 up 1:04, 2 users, load average: 0.73, 0.68, 0.69

ondemand is the system CPU governor.
$ cat /etc/init.d/ondemand | grep -i short
# Short-Description: Set the CPU Frequency Scaling governor to "ondemand"

I hope that helps the debug team and give people a possible fix.
