I just got a run_timer_softirq oops on my own laptop, slightly different. That was not during shutdown, although there was a "yum upgrade" finishing when that happened, so it's quite likely that there was a service shutdown (and then restart). I think it's related. But my oops has almost no information: the IP that was jumped to was bogus, and the callchain is just CPU idle followed by the softirq -> run_timers_softirq handling, so there's no real way to see *what* triggered it. The bad rip was ffffffffa051e250, which is not a valid code address. It *might* be a module address, though. So this might be triggered by rmmod on some module that doesn't remove all its timers...
