Description of problem: Tried installing and running the current fc3 updates/testing kernel to be able to run oprofile on my laptop and it didn't get beyond the point where it says "uncompressing kernel image" or whatever the wording is.

Just for posterity what kernel are you running (rpm -q kernel)?
[kmaraas@localhost ~]$ rpm -q kernel-smp kernel-smp-2.6.10-1.753_FC3 [kmaraas@localhost ~]$
And still the same with the -1.762_FC3 kernel
it's no surprise to me really. a lot of UP hardware (especially laptops) doesn't like having APICs messed with. It's unlikely that this will change any time soon, without significant effort upstream to isolate the problems on each and every case, and work around them accordingly. You should be able to use oprofile in the UP kernel however, but it will use an alternative timing source due to the lack of APIC.
