Description of Problem:

Intermittently (groan) "shutdown -r now" reaches the end of the messages
about things it's switching off, prints "Restarting system" and then just
sits there. 

SysVinit from the CDs burned from the RH 7.3 release.

How Reproducible: It happened two or three times in a row until I 
tried it again just to confirm it was always. Then it worked. 

Steps to Reproduce:
1. Sony Vaio PCG-SR1K laptop with RH 7.2. Upgrade to RH 7.3.
2. Boot to text (I don't boot straight to X)
3. "shutdown -r now"

Actual Results:

All the shutting down messages until "Restarting system". Then it doesn't.
Have to power off with the power switch, and then switch it back on again
for it to reboot.

Expected Results:

Shutdown and reboot :) 

Additional Information:
	
I don't know whether this is relevant, and it may be my imagination. I have
always used "poweroff" and "shutdown" as a normal user rather than root on
the laptop, relying on "I own the console, it will do it". I have never needed
to shutdown -r recently, so I don't know whether I needed to be root for that
always.

Since upgrade, I find that "shutdown -r now" won't work if I am end-user;
I need to sudo it. There's nothing in the changelog about this. Is this just
my imagination or has it changed? Is it remotely relevant? (Doubt it, but
you never know.)
