kernel:BUG: soft lockup - CPU#15 stuck for 67s! [iptables:18868]

I am facing exactly the same problem as described on It is a Cloudmin system, was working just fine, this is the first time I see this. I keep my servers updated and I believe this one also should have been upgraded. I just can’t login to it to see the kernel version. The VPS guest systems are working just fine on it, I just can’t get through to root. Will simple reboot make a trick?

Edit: Yep, simple reboot helped.
