I have to Shutdown and then switch on again to do a proper reboot from within (K)Ubuntu. This does not happen with Mandriva. However on my desktop system a reboot from Kubuntu works fine. I suspect it is an ACPI bug and I reported it to Ubuntu about, oh, two millennia ago.

I am having the issue on a desktop system that is running Kubuntu/Ubuntu 
9.10, Mandriva 2010.0 and Win 7. I do not necessarily agree that it is 
an ACPI issue as Mandriva is very heavily into using ACPI (although one 
way to test this is to turn ACPI off in the kernel at boot time). In my 
view the solution to the issue is simple, Mandriva issues a global 
killall command as the last thing before shutting down, Ubuntu should do 
the same thing.
