Bug#391876: Shutdown/reboot does not work sometimes

[Andriy Lesyuk <s-andy@in.if.ua>]

Package: ksmserver
Version: 3.5.4-2+b1
Severity: important

Sometimes when I press "Shutdown" or "Reboot" button in the Session 
manager window (first bottom item under "K" menu) it does not really 
shutdown/reboot the machine. Screen becomes black but that's all. The 
machine just freezes.

I tried to change HaltCmd and RebootCmd in the kdmrc file. But as I 
figured out these command are not called when machine freezes. So it 
freezes before calling them. As I understood the problem is in 
ksmserver. I have no idea how to debug ksmserver that's why I just can't 
give more info about the problem.

I'm using fglrx driver (8.25.18). Possibly this driver is the reason. 
The same problem takes place on my job machine (also using fglrx). 
Interesting thing that it appears after several updates (may be just a 
coincidence).

I understand that this info is not enough for finding the reason. But I 
need some help to know how can I provide more info because I don't know 
ksmserver/kde internals. I'm ready to do everything you need to help you 
find the reason.

Thanks,
Andriy
