You're right.  It cannot be killed.  Your only option may be to stop and start SQL services.

thanks Greg, do you think since checkpoint is stuck, I am going to have loss of data?

There are several events that cause a checkpoint.  One of them is shutting down SQL server.  So, it will try to checkpoint when you restart SQL.  I'm honestly not sure what it will do if it can't checkpoint.  

I just had another thought.  You can manually force a checkpoint by running the CHECKPOINT command.  You might want to try that first.

To answer your question, you shouldn't experience any data loss.  The transactions are stored in the transaction log.  Upon restart SQL will read the transaction log and either rollback the uncommitted transactions or re-execute the committed transactions to get the SQL server back to its original state when it was shutdown.

I tried manual checkpoint but it doesn't work... when I check the activity monitor, it shows that spid 10 is blocking it... (which is the same checkpoint when i run sp_who)...

the database is in simple recovery mode, would that still work with restarting the database and reading it off of transaction log?

The recovery model doesn't matter at this point.  This is a core function of SQL server to maintain data consistency.
