The patch below does not apply to the 5.10-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to stable@vger.kernel.org.

I had a look at this and the other ones that failed to apply. I tried to apply this commit ( commit b8c824a869f220c6b46df724f85794349bafbf23 ) to all of them and then built it.

5.10.y: success 5.4.y: success 4.19.y: success 4.14.y: success 4.9.y: failed

So I'm not sure why the automated stuff failed for you for 4.14.y through 5.10.y.

Considering it worked for me and built successfully can you have a try with it again at least on 4.14.y +?

Thanks,

thanks,

greg k-h

Saving/restoring interrupt and wake status bits across suspend can cause the suspend to fail if an IRQ is serviced across the suspend cycle.
