2016-09-28 Thread Kamal Mostafa

Thanks for this information, Gabriel.

Your understanding is correct: the original probe path oops is fixed in
4.4.0-41.61, which will land in the -proposed archive by tomorrow
(alternately, available now from our staging PPA: https://launchpad.net
/~canonical-kernel-team/+archive/ubuntu/ppa/+packages

And we'll pick up the missing error path fixup commit as well (for the
next Xenial cycle).

[Kernel-packages] [Bug 1620317] Re: ISST-LTE:pNV: system ben is hung during ST (nvme)

2016-09-27 Thread bugproxy

--- Comment From gbert...@br.ibm.com 2016-09-27 23:02 EDT---
Hi Canonical,

Our test teams had problems with booting the Ubuntu-4.4.0-40.60 kernel.
They hit an Oops in the NVMe probe path.

My current understanding is that this is already fixed in your kernel by
the fixup commit: e9820e415895 (" UBUNTU: (fix) NVMe: Don't unmap
controller registers on reset") which will be published in kernel
Ubuntu-4.4.0-41.61.

We will try again with that version.

While we are here, I noticed another issue with the backport of
30d6592fce71 (" NVMe: Don't unmap controller registers on reset").
Looks like you are missing the fixup commit that went later into the
4.4.y tree:

81e9a969c441 ('nvme: Call pci_disable_device on the error path") #4.4.y
tree.

I opened Bug 146899 to track this.  It will be mirrored soon.

[Kernel-packages] [Bug 1620317] Re: ISST-LTE:pNV: system ben is hung during ST (nvme)

2016-09-26 Thread Brad Figg

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-
xenial' to 'verification-done-xenial'.

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!
