So, I have removed both my SATA disks and tried to reboot:
the system stalled without any error message at all.

After that I installed gentookernel and re-created initramfs image
(the previous one was created by the gentoo-kernel package before
the removal of the SATA disks).

After that, my Gentoo system successfully rebooted from the only
(ATA) disk that remained.

So, the problem is partially solved.

However, I still do not understand the exact reason for it to appear.

Most probably, both my SATA disks have connection problems as
Oli Schmidt suggested from the very beginning, and because they
both have it, it points to the motherboard that already had quite
a bad track record.

Unfortunately, I cannot diagnose it further, but later will try
to experiment with attaching my SATA drives again.

Also, I am going to test voltage outputs of my Enermax power
supply unit when I will have such a possibility. It is quite old but
was not used intensively. The other one, Thermaltake, is even older,
was intensively used everyday, and still had no problems. (Both
were bought with a big margin with respect to my computer's
power demand).

Thanks to all who replied to this thread.
