Hi Christoph,

I see this was already discussed in 2 threads:

 https://lists.infradead.org/pipermail/linux-nvme/2019-April/023234.html
 https://lkml.org/lkml/2019/5/24/668

but in latest git the issue still exists.

I hit that on each resume on my Acer Nitro 5 (AN515-43-R8BF) Laptop.

...

The patch from Dongli Zhang was rejected the time without any other fix
or work on this issue I could find.

Are there any plans to fix that or any code to test?

Best Regards,

I guess the following patchset may address it:

https://lore.kernel.org/linux-block/20190812134312.16732-1-ming.lei@redhat.com/

The patchset can be applied cleanly on for-5.4/block.

However, the warning can't be fixed, even though the issue and
the patchset is closely related.

The warning just means there isn't any online CPU in this managed IRQ's
affinity. Once we can guarantee that there aren't any in-flight requests
for dead hctx(no any online CPU in its affinity mask), the warning
can be removed.


thanks,
Ming
