I've been running FC4 for several months now and have been using

update without problems. The system has been automatically selecting

system hung repeatedly. I was only able to get past this by selecting
2.6.14.1.1644_FC4 instead of 2.6.14.1.1644_FC4smp from the boot
I'm having the same problem.
My SCSI based Dual Opteron machine (x86-64) fails to boot with 1644.
Somehow, the adatec79xx driver init fails, leaving me without the root
LVM. (From there, attempt to kill init, panic.)
Can you post your machine configuration?
configuration menu.
It was just a guess. I have no idea why this worked.
According to
webopedia.com, SMP is "Short for Symmetric Multiprocessing,
a computer architecture that provides fast performance by making
multiple CPUs available to complete individual process simultaneously.
Unlike asymmetrical processing, any idle processor can be assigned any
task, and additional CPUs can be added to improve performance and handle
increased loads."
I doubt that this has anything to do with SMP. machines.
However, it is possible that the SMP configuration on 1644 is burked.
Did you try older kernels?
Does this refer to other processors on the same computer or on different
machines on a network? The other machines on this very minimally
networked LAN (just for ssh) aren't always up or running FC4 when they
are up. None of these computers are dual core. I'm not trying to do
any smp-type processing at this time.
No.
SMP means:
Single machine with multiple logical or physical processors.
In general, you can view an SMP machine as car with multiple engines
working concurrently. (Instead of a single engine)
Could the smp kernel ran into some sort of synchronization problem with
the other machines and now be "parametrically confused" about something?
I'd like to either (1) reset it or (2) fix the update process so that
the default is for non-smp kernels. Thanks for any suggestions.
Again, I doubt it.
