Thank you both, Milos and Chuck. Now I plan to become a bit
difficult ;)
What would be the fast-track in learning as to Fedora and hardware ?
It's a pity that there isn't a "Fedora-docking" site for exchange of
configuration files per computer model !
( I don't know half of what the kernel configure options are, what is
needed, and all that. Haven't compiled a kernel in years ) Then of
course, there are all sorts of config files many other places.
Chuck, - I am not sure I understand what you meant

Your thought here is that the 8254 timer is connected to day/time clock ?
( if not, I sure would have a problem in detecting a wrong speed )

Hmm...guess that might work like it is running at the moment, except you get rid
of the message.
Since I wrote and asked, then attempting to understand your ideas here, I just had
some closer look at the topic.
The ERROR seem to be:
ACPI Error (tbfadt-0453): 32/64X address mismatch in "Pm2ControlBlock": [00008800] [0000000000008100], using 64X [20070126]
A software bug, a wrong value set in the Fixed ACPI Description table. This is serious, many times you will not be able to start the kernel. A long list of errors,
as only one CPU will run, pluss other related problems. I think the 8254 is used
for trottling and such. This timer may also involve the interrupt structure. The wrong addressing may be the reason for the later problems seen in the "dmesg" files
that I included. For some reason, when the latest kernel refuse to run, I may start
the computer with the older kernel. Then the latest kernel may start working again.
The serial port ( modem ) doesn't work, and I don't find io from switches etc. - but
the card-reader and USB seems to be in place.
This should be reported to those that is dealing with this stuff. ( not sure how to
report the error, if it is redhat or linux, etc.)
Are there any pages of a conceptual schematic or structure for the hardware anywhere ? ( guess they don't write code without )

Try the "enable_8254_timer" kernel option? If that works, make sure
the system clock isn't running twice as fast as it should.
