The ghosts cannot be released from Sild's spell even after he is killed, and will remain hostile.
If the player walks up to the Word Wall, while bypassing the trapdoor, then sneaking downstairs to where Sild resides, Sild will be looking up at the ceiling around the perimeter of the cage around the pool of water and trying to coax the player (whom he still believes to be around the empty chest upstairs) to come through the trapdoor by saying, "Come on, you know you want to."

PC 360 PS3 The gate to the trap may be unlocked.
PC Sometimes, after finishing his dialogue, Sild will not turn hostile.
360 Installing Dawnguard may cause issues with the quest Preemptive Strike from Gunmar, especially if the location is Rannveig's Fast. The Nightmaster Vampire will be in the room with Sild, and will turn hostile upon seeing the Dragonborn. This seems to turn Sild hostile as well, preventing hearing his monologue.
Sild's assistant, a female Dunmer, is lying dead on the floor nearby. Sild refers to his assistant as a "he" in the monologue.
PC If the Dragonborn falls in the trap and acquires the key of Rannveig's Fast either from the bag near Silds apprentice or by pickpocketing Sild, a follower may open the cage and allow the Dragonborn to leave it with Sild remaining passive.
At the word wall, the word sounds play but there is no visible word and no way to learn that word, making it impossible to get the "Thu'um Master" achievement.
If a follower falls through the trap at the word wall, they may reappear after a moment, apparently bouncing up out of the hole.
Sometimes the Stone of Barenziah will not be in the spot it should be in.
It is possible to enter Rannveig's Fast through the back entrance by climbing up a nearby stone and using the Whirlwind Sprint Shout. This can lead to a number of the bugs above.
After joining the Companions and getting the quest Trouble in Skyrim where the Dragonborn has to clear out Rannveig's Fast it can be impossible to complete if it has already been cleared out before hand, this may be due to having Dawnguard installed, and having being sent to kill the vampire inside and killing Sild.
