I'm also getting this warning since 2.6.28.1, which incorporated commit
1c5745aa380efb6417b5681104b007c8612fb496 ("sched_clock: prevent
scd->clock from moving backwards, take #2") as commit
e268dcdd404f4558cdd24c8ecede3e064df8fa33, this being the patch that
introduced the WARN_ON(timekeeping_suspended) check.
