problem with initial Linux kernel booting on Sandpoint

[Viktor Lapinskii]

Hello!

I am having problems booting HardHat Linux kernel on Sandpoint.

After uncompress_kernel() writes the message

Now booting the kernel

and the booter jumps the the kernel, there is a delay of at least 40
(forty) minutes before the kernel displays the messages (see the log at
the end of this message).  Then it hangs forever having displayed a
warning about the real-time clock.  I tried both the "standard" HardHat
kernel and custom-built ones.  Results are the same.

I would appreciate any suggestions as to how to approach this problem.
