Hi Joseph,
I am not sure if this is fixed. Dimitrenko changed the status to "Fix
Released". I had asked if this was as intended and if there is indeed a kernel
with the fix but have not gotten a response. I think we should proceed with
further bisection.

Is the linux-image-extra mandatory for all kernels? I am asking this
because 4.4.0-59 boots cleanly without the extra package.

Hi Joseph,
Is it possible to provide me with multiple kernels with different bisects?
I can then run through them in quick sequence and provide you an update. This
was we can minimize turn-around time. Due to this bug we are unable to move to
newer kernel that have security fixes for high
I checked the latest released Ubuntu kernel (4.4.0-83) and it does _not_
have a fix. So I am changing the status of the bug back to "confirmed".
If a fix has indeed been released please let me know where I can pick up
a new in-development kernel.

Hi Joseph,
Any updates on this? Let me know if you had a chance to generate another
kernel after a new bisect.

Thanks for taking time to look at this bug. Due to this nvme issue I am
not able to go to newer kernels that have important security fixes. Here
are the results.

nvme devices are listed under 'lspci'. I did check that nvme
360c486c91 works fine. Time to move to the next commit.

Just to note, my earlier hardware is tied up with some other work. I
moved my testing to another hardware with Intel NVMe instead of the
earlier HGST one. But the issue was seen on both Intel and HGST, the
only two vendors' NVMe we have in-house. Both servers are Cisco UCS
C-240.

I need a little more time to test the kernel. The hardware I was working
on is tied up with something else. I am working on getting that freed up
or get another identical one. Once I get hold of one I'll have the

image-4.4.70-040470-generic_4.4.70-040470.201705251131_amd64.deb and it
works fine with PCI passthru Intel NVMe and HGST NVMe drives.
With the way our VM is built I do not have apport installed but I'll be
happy
Just to confirm, mainline kernel linux-
image-4.4.70-040470-generic_4.4.70-040470.201705251131 works fine. Looks
like the bug is fixed in mainline. Should I still continue with the
bisect task with 4.8+ kernels?

Thank you for your patience. I now have the servers back with me. I just
tried mainline 4.13.1 kernel as suggested by and it boots fine. All nvme
passthrough devices come up fine.

Would you be able to point me at all the ubuntu specific patches that
are applied on top of mainline kernel? I can run some bisection on my
side to understand what might cause the issue.

This was confirmed to be a VMware ESXi bug in their MSI-X code path for
PCI passthru devices. VMware has fixed this bug in their latest patch.
