The system freezes at '$'.
The word 'kickstart' does not appear.

If the original BETA2 kernel is bootet, the system does NOT hang.
After this boot, booting the kernel with polling built in, and
the system does NOT freeze.
Power OFF ... ON ... boot: The system hangs not.

One day later (three times/cycles) the system hangs again
with the polling kernel.
Hangs not with the original kernel.
And thereafter hangs not with the polling kernel.

And so on.

The original kernel repairs the boot process for one day.
Next day: freeze.
>How-To-Repeat:
Boot again next day.
>Fix:
First, using the original BETA2 kernel.
