A condition of the the operating system when its state is so broken that imminent shutdown is preferred.

A condition of the the operating system when its state is so broken that imminent shutdown is preferred. This may be caused by hardware failure but is also frequently caused by various kernel bugs, driver bugs, misconfigurations and attempts to use incompatible modules.
