I had a more severe reaction one time in Linux. I don't remember if it was Redhat. Ubuntu or what. When I came up to the XWindow manager and logged in, all seemed fine. But when I right clicked on the desktop clock to set the time, my monitor went out of sync. I had to power it down and kill the power on the tower to avoid burning out the video hardware.
Whatever distro it was, it was gone! Can't leave a time bomb like that lying around.
