This series contains a fast fix for the basic GPU poweroff functionality and goes further by implementing interrupt masking and synchronization before suspend.
For more information, please look at the conversation at [1], which explains the regression seen with the poweroff commit and the initial approaches taken to solve that. Cheers!
