Last thing when I look at the output of dmesg I get the

I can submit a patch, but I'm not sure what to do.
The code loops through NR_CPUS and ignores the ones that are not online: if (!cpu_online(i)) continue;
This code used to work, but the hotplug changes broke it. What's the correct code now to check if a cpu isn't available?
Hi Andi/everyone, To test the timing issues I altered the boot command line, see below: root=/dev/sda3 vga=0x317 selinux=0 notsc resume=/dev/sda2 splash=silent But when I look with dmesg I see the following: AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ stepping 02 CPU 1: Syncing TSC to CPU 0. CPU 1: synchronized TSC with CPU 0 (last diff 0 cycles, maxerr 539 cycles) Brought up 2 CPUs Disabling vsyscall due to use of PM timer time.c: Using PM based timekeeping. I don't fully understand this message, but if I were a gambling man, I would say that this isn't what you'd expect to see? :) Best wishes, Jon -- Jonathan Brooks (Ph.D.) Research Fellow PaIN Group, Department of Human Anatomy & Genetics University of Oxford, South Parks Road, Oxford, OX1 3QX tel: 01865 282654 fax: 01865 282656
