First let me ask you - why we have to enable vlbank as part of pflip, I understand why it has to be enbbled in WAIT_FOR_VBLANK IOCTL but not sure about PFLIP IOCTL. IMHO in atomic as before in legacy page_flip, it's up to the driver implementation in atomic_commit hook to manage vblank ISR on,off. > > Andrey, did you check via code audit and/or testing that the vblank > reference count is still balance...
