NMI occurs normally when the system sees memory or other errors. Thats why its logged. Doesn't neccessarily mean the problem in every case is that of course. Do any other D610 users see the same NMI - I'd be interested to know. As to workarounds. I'd run memtest86 on the system to see if the NMI is coming from a memory error. If memtest86 passes then file a bug in case we have other D610 users seeing it and don't worry further
