If you're on a PvP realm, you may have noticed that with the release of Patch 5.3 that things have gotten kind of hectic at the Seat of Knowledge, where Lorewalker Cho hangs out when he's not pushing buttons randomly in MSV. Apparently the guards at the Seat simply cannot cope with the increased volume of Horde/Alliance aggression, and players who die in the fracas are finding out that they can't easily get back to their bodies.
Rygarius, ever the helpful hippogryph, informs us that there's a hotfix
on the way to smooth out these issues and allow players to get back to their bodies if they die ignominiously at Cho's feet. Or in the vicinity of his feet. His feet will be close, is what I'm saying. We're told that the hotfix may require a realm restart to take affect, so be on the watch for that.
