@Kenneth, do you know if there have been some related patches/debug methods
which have fixed some bugs related to the BO underallocation? can you have a
check and provide some example of them so that we can evaluate current issue
and see if there are some log/method for further debug?
those two issues seriously blocked the customer's milestone, mesa/kernel
upgrade may only met requirements of future release.</pre>
