Hi all,
I am testing suspend and resume functionality on imx6Q with android nougat. When i try suspending, module trying to go into suspend state and getting below issue and then resuming.
dpm_run_callback(): vpu_suspend+0x0/0x158 returns -11
PM: Device 2040000.vpu_fsl failed to suspend: error -11
This is happening continuously (meaning trying to go into suspend and resuming on failure) until i try resume (By moving mouse or pressing power button).
Please help in finding why suspend failing.
Please find attachment for full log.
Thanks
Susan
