Check this KB article reference SQL deadlocks;
Personally I would be loathe to do a rollback right now. Get your customer to check his DA searches for consistency, and if they're OK, try and resolve the deadlocks. The only times that DA has failed on an upgrade for me, none of it worked from the get go.
