Booting stops with disabled wait state
An automatic processor type check might stop the boot process with a disabled wait PSW.
On some distributions, a processor type check is automatically run at every kernel startup. If the check determines that the distribution used is not compatible with the hardware, it stops the boot process with a disabled wait PSW.
If this problem occurs, ensure that you are using a distribution that is supported on your hardware.
If you are using an SCLP console, you might get a message that indicates the problem.
