Kernel panic, becoming frequent - any suggestions to cause? Log enclosed.

Hi there.

Early 2015 15" MBP running Yosemite 10.10.3.

Over the last week or so I've had probably 5 kernel panic crashes. Log from the latest below.

Starting to get a bit concerned - I'm hoping this isn't a hardware issue. Is anything identifiable from the log?

Thanks.

Ed
