Public bug reported:

---Problem Description---
Some CAPI Flash cards need notification of device shutdown
in order to flush pending I/Os.

A PCI notification hook for shutdown has been added where
the driver notifies the card and returns. When the device
is removed in the PCI remove path, this code will wait for
shutdown processing to complete. It could take a minimum of
1 second for shutdown processing to complete. To avoid an
indefinite wait, code has been added to read the status 
incrementally from 100ms up to 1.5 seconds.

This is a defect placeholder for submitting a patch to Canonical, that is in the process of getting submitted upstream for the 4.8 kernel.

We would like to have this patch included in the pointrelease, 16.04.1.

Please lookout for the patch that will be attached to this bug soon and
probably closer to the deadline for 16.04.1.

I will submit the patch as soon as I get the review comments addressed
and well tested.
