Narrative:

After start of taxi on taxiway 'B' cockpit crew noticed an odor in cockpit -- captain asked me if I smelled anything -- odor became stronger and was evident it was smoke. About this time, flight attendant called the cockpit and while the captain was talking to the flight attendant I heard passenger yelling 'smoke' and 'stop.' captain told me to tell ground we were stopping and immediately stopped and opened the cockpit door. A thick bluish smoke was in the cabin with visibility inside restr to row 18 or so (about 1/2 way). I told ground control we're stopping the aircraft and roll the emergency equipment. I reached up and turned off the air-conditioning packs and closed the bleed valves. Smoke was still present and captain called the evacuate/evacuation checklist and called for an evacuate/evacuation aircraft forward -- (all 45 passenger were seated ahead of emergency exit rows, wings, for weight and balance). After completing evacuate/evacuation checklist I noticed 2-3 passenger outside walking very fast toward 4L the active departure runway. I told the captain I was leaving to 'round-up' the passenger. After deplaning, I noticed port authority/authorized had parked a 'stair' truck by the forward right door and door was not opened, nor slide deployed -- all passenger now all out of door 1L. Later, I found that the right forward galley service door had been blocked by the truck. In the end, I feel the assessment of the situation and action taken were appropriate and done 'by the book.' the only problem was the blocked door which could have been disastrous if fire was present and more passenger had to be evacuate/evacuationed. Callback conversation with reporter revealed the following information: reporter was contacted and revealed the following details. The aircraft was a MD80 and the smoke was caused by hydraulic fluid leaking on the APU and ingesting the fumes and vapor into the air-conditioning packs. All the emergency equipment that was used worked normally except the forward right door. During the evacuate/evacuation a cabin attendant attempted to open the forward right door and deploy the evacuate/evacuation slide but found the door blocked by an emergency vehicle. The reporter believes it is airport emergency procedures to position entrance stand truck to the evacing aircraft. The reporter states that no contact was made by the FAA.
