Hi,

        Our tablet have one issue which can't resume back after system enter suspend mode. It rarely happens but if it happens, we only can do is resetting our tablet. And we found the issue seem like the known issue track ID ENGR00171011 which is listed in i.MX_Android_R10.3.2_Release_Note.html
or i.MX_Android_R10.4_Release_Note.html. We want to ask this issue is solved by FREESCALE? If yes, where do I get the patch for this issue.If no, can FREESCALE provide any official document or test data to let us provide it to our customer for explaining this issue?

Hi Leon,

Sorry for the very long delay in responding to this.  Just wanted to see if this is still an issue for you.  Can you please let me know if you are still experiencing this issue?

Thanks,

Grant

We experience this issue now. We use very old kernel - 2.6.35 and we would prefer to stay with it, if it was possible.

I've found out that the issue is somehow related to IPU. Excluding it from kernel configuration makes suspend/resume work correctly.

Is there any way to access information on ENGR00171011 at the issue tracker?

It's notable, that the watchdog doesn't help us in that case. It hangs forever, even though the watchdog was enabled.

Any help and information on issue are appreciated.
