Description Kjartan Maraas 2005-02-02 13:50:28 UTC

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)?

Comment 2 Kjartan Maraas 2005-02-02 23:06:32 UTC

[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

Comment 4 Dave Jones 2005-02-09 09:11:23 UTC

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.
