Snoop Dogg's Super Bowl week just went to pot, and not in the good way -- someone made off with equipment for a bunch of shows he's doing in San Francisco.

Law enforcement sources tell TMZ an SUV parked on a city street Monday night had a bunch of laptops, luggage, and concert gear -- and someone busted a window and cleaned out the vehicle.

Snoop is scheduled to play Tuesday night at The Regency Ballroom. We're told the equipment that was taken was essential for that gig. He's also playing a few other events related to the Super Bowl in coming days.
