Kam's message which mentioned the smp only version of the kernel instead 
of having a separate smp and uni version might explain the problem. I'm 
adding Kam's posting to this message so I can thank Kam as well for the 
information of the possible reason.

Thanks Kam for the explanation.

It is strange that it does not work for certain platforms. I guess you 
might file a bug report for the problem mentioning the SMP kernel. I 
thought FC5 had a seperate uni version and an smp version. Maybe it was 
considered safe to compile the uni version with smp enabled for the 
later kernel versions.

Since FC5 came with a uni version which had no smp enabled originally, 
you might try installing the original version for testing from FC5 using 
rpm -Ivh --oldpackage <kernel-version.rpm>
and reboot into this kernel to see if this older version will shut down 

After that, you might have hope for FC5 but will need the problem Kam 
mentions getting resolved with the one SMP enabled kernel version.

The only other option probably would be to compile a custom kernel and 
turn off SMP support in the configuration. Either that or there might be 
yet another need for a kernel switch like nosmp as a kernel parameter.

After a few boring years, socially meaningful rock 'n' roll died out. It 
was replaced by disco, which offers no guidance to any form of life more
advanced than the lichen family.
