As you can see in that bug tracker, we have spent a lot of time to come up with 100Hz kernels, kernel-vm. These kernels do not have problems with clocksource=pit. Until this bug is eliminated upstream, I think kernel-vm offered by CentOS may be the best solution (shameless advertisement). I just hope it won't take long for the upstream developers to find a fix for the problem associated with the divider= option. Akemi / toracat
