What lengthy log? :-) This was it! Before those lines was the "Kernel
panic" lines. "Not syncing: No init found.", "Try passing init=
option", etc. etc.

Then "Call Trace:' before those lines.

I am not a kernel hacker nor have I played the part of one in movies of
TV :-) but I am thinking more and more there is a problem with the
initramfs image for the most current version.

    That is why I hope Daniel will catch this thread and offer some
thoughts or a previous kernel (source or binary) RPM. Even the patch
files he used would be nice.

    I could see about using the current RPM source and back porting (?)
its patch file(s) to the older kernel.
