I’ve seen a lot of people complaining about getting this error in Phase 2, but if you get this during Phase 1 – you probably forgot to add a rule for the IPSEC traffic to the firewall policy.

Debian 6 (Debian Squeeze) & Debian 7 (Debian Wheezy) reboot… doesn’t.
Someone made kexec-tools handle reboot requests by default seemingly. This allows the system to skip BIOS/POST etc and just drop to a minimal runlevel and start a kernel again.
This is great if you only have debian on your system and particularly great if you spend a lot of time changing kernels – when you issue reboot, or shutdown -r now (etc) kexec-tools intercepts the command and does a warm-restart rather than resetting the machine cold – if you don’t need to, why wait through all the BIOS checks, bootroms, etc, right?
Except some of us reboot because we want to change OS. I’d argue that it should perhaps be the default behaviour to cold-reboot (and the installer could, perhaps, ask!) or that KDE should have a button for “warm restart” and one for “cold reboot” or whatever, but anyway.
If you want to make reboot actually reboot the system you’ll want to:
# dpkg-reconfigure kexec-tools
And tell it to not use kexec-tools to handle reboots. If you’re never going to want kexec-tools, you can probably uninstall it using apt, but I just disabled it. It’s useful on the odd occasion I do want to just upgrade the kernel to enable it, reboot, and disable it again, I suppose.
Some SEO, perhaps?

Debian 6 (Debian Squeeze) KDE4 Override Screen Resolution
Everything you needed to know about manually overriding incorrectly probed screen resolutions but nobody thought to write down, seemingly:
$ xrandr -q Screen 0: minimum 320 x 200, current 3600 x 1080, maximum 8192 x 8192 DVI-I-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1600x1200 60.0 1680x1050 60.0 1400x1050 60.0 1280x1024 75.0 60.0 1440x900 59.9 1280x960 60.0 1152x864 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 72.8 75.0 66.7 60.0 720x400 70.1 DVI-I-2 connected 1680x1050+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0 800x600 60.3 56.2 848x480 60.0 640x480 59.9 1680x1050 60.0*
This output shows what xrandr has detected. In my case, DVI-I-2 wasn’t showing the 1680×1050 resolution I needed. It’s there now because this output is from after I made my modifications.
$ xrandr --addmode DVI-I-2 "1680x1050"
Was all it took.
Sadly, of course, this is all lost on reboot, despite making changes in the System Settings/Display panel and saving them as default – because even though my screen alignment settings were saved in $HOME/.kde/share/config/krandrrc, the mode 1680×1050 isn’t remembered as being valid for my screen.
Because krandrrc contains a config element like this:
[Display] ApplyOnStartup=true StartupCommands=xrandr --output "DVI-I-1" --pos 0x0 --mode 1920x1080 --refresh 60\nxrandr --output "DVI-I-2" --pos 1920x0 --mode 1680x1050 --refresh 59.9543
I simply elected to try adding:
xrandr --addmode DVI-I-2 "1680x1050"
To the front end of StartupCommands, like so:
[Display] ApplyOnStartup=true StartupCommands=xrandr --addmode DVI-I-2 "1680x1050"\nxrandr --output "DVI-I-1" --pos 0x0 --mode 1920x1080 --refresh 60\nxrandr --output "DVI-I-2" --pos 1920x0 --mode 1680x1050 --refresh 59.9543
On reboot, my screen resolution is correctly set, and my dualhead config works as expected. Now I just need to remember never to change my screen settings again, or be prepared to make that change again.
