I found the following information on Metalink (a great place to look for information on specific errors):

=======================================
1- A similar bug 953585 that is reporting similar issue. It seems that the issue is related to the timeout on the
checkpointing procedure. Please try their wrokaround of play around with init.ora parameters checkpoint_interval,
and any parameters you are setting for db buffers to isolate the problem to some degree.


The customer logging the bug has solved his issue by increasing the value of checkpoint_interval and the value of
_control_file_enqueue_timeout=2700

2- In some cases, you may encounter an error such as:

Instance terminating due to error 1110.
Instance terminated by CKPT PID=505


A third party software, most likely a backup application, has locked a
datafile or logfile. We have seen this situation with Seagate Backup
Exec Software. When Oracle attempts to write to the file, the lock prevents
it and the database crashes.


====================================

It looks like the second scenario matches your problem pretty well.
