Database won't startup after system crash

One of our systems crashed yesterday and now one of the databases that was running on it won't start up. When I try to startup the database, it looks like everything is fine until it tries to open the database.

It does the crash recovery, but then terminates when opening the database. The messages in the trace file are the same as in the alert log. Per Oracle Support, I tried setting an init parameter to offline the rollback segment, but that didn't make any difference.

I did a dbv on all of the datafiles and got no errors.

Any comments/suggestions? I do have an open SR...My Oracle Support seems to be functioning better today.

I'm getting the following message in the alert log:
