  Broken PowerNV PCI hotplug driver - Patch backporting to zesty
   
  Machine Type = Supermicro P8DNU 
   ---Debugger---
  A debugger was configured, however the system did not enter into the debugger
   
  ---Steps to Reproduce---
   On ubuntu (zesty), the NVMe adapter hotplug functionality is broken. After 
check, there are 3 more patches needed.
   
  There are 3 upstream patches needed by ubuntu.zesty are:
  [1] 
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d7d55536c6cd1f80295b6d7483ad0587b148bde4
... which reads "drivers/pci/hotplug: Handle presence detection 
change properly"
  [2]

[Kernel-packages] [Bug 1680328] Re: Broken PowerNV PCI hotplug driver - Patch backporting to zesty

[Hank Chang]

Willie Liauw  verified the related NVMe
hotplug driver by building & installing the latest tagged kernel from
zesty git (tag 4.10.0-21.23, git://kernel.ubuntu.com/ubuntu/ubuntu-
zesty.git)

So, changing the tag to verification-done-zesty..

Thanks!

[Kernel-packages] [Bug 1680328] Re: Broken PowerNV PCI hotplug driver - Patch backporting to zesty

[Kleber Sacilotto de Souza]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
zesty' to 'verification-done-zesty'. If the problem still exists, change
the tag 'verification-needed-zesty' to 'verification-failed-zesty'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Only commit 454593e54cac126a0f49d4b65f90a5e518c51404
('drivers/pci/hotplug: Mask PDC interrupt if required') is required as
the first 2 are already applied.
