Diskless PXEboot crashes at kernel loading.

I already described in detail what I've been doing
with the FreeBSD server and the Compaq HP client PC

The Bootp exchange seems to be fine and the client
gets the kernel from the server. However, during
the kernel loading, the client PC "implodes" and
starts from BIOS boot up again. The boot messages
are given below.

The crash messages scroll too fast over the screen
to see the details with the bare eye. I recorded it
with a digital camera and a snapshot of it is here:


The whole boot process in plain text goes as

    Welcome to FreeBSD!

 [ Boot option menu 1 to 7 ] FreeBSD-ascii-cartoon

/boot/kernel/kernel text=0x4d568c /

And the crash happens.
Note that the crash occurs for whatever option
1 to 6 I choose from the FreeBSD boot menu.

Does someone understand the crash messages?
