== SRU Justification ==
IBM is requesting these nine patches to be SRU'd to Bionic. IBM found
that the current Bionic kernel contains a problem related to qla2xxx
driver which causes the following:

Medium. There are nine patches in this pull request. They are not specific
to a
paticular arch, but they are specific to qla2xxx.

A test kernel was built with these patches and tested by IBM.
IBM states the test kernel resolved the bug.

Canonical or Breno,
can we move this to accepted/verified? When is the release to customers
due?

Canonical, please confirm. I see kernel linux-image-4.15.0-23-generic as the
latest for -proposed. Is this the kernel that contains this fix?

sorry folks,
After the submission I have noted the wrong authority in the set by me,
and so I updated the patch 1/9 fixing the author to Quinn Tran instead.

Using kernel from http://kernel.ubuntu.com/~jsalisbury/lp1770003, I have
confirmed that the disks are discovered and I am running some scenarios now.
Doing portdisable/portenable from the FC switch occasionally, while running HTX
I/O load. No problems seen so far.

Looks like the OK kernel completes the FC login, while the NOK kernel
does not. I believe there were some extra patches added that may be
missing other requirements. Looking at the two different patch lists, I
see this:
1) "scsi: qla2xxx: Fixup locking for session deletion" is missing from
the NOK kernel.
2) There are 16 added patches to the NOK kernel, which were not be
required when we built our test kernel.
It's possible those 16 patches are missing some critical companion
patches, but it should not be necessary to add those 16.
I don't think it is any more acceptable for SRU, but I'll bring it up
anyway: another option is to do a full qla2xxx driver refresh to version
10.00.00.04-k, plus the "scsi: qla2xxx: Fixup locking for session
deletion" patch (a vital fix).

--- Comment From dougm...@us.ibm.com 2018-05-11 09:55 EDT---
While trying out the proposed kernel, which does now install as expected so
that I can boot either, I run into a problem accessing the SAN. With the stock
4.15.0-20-generic kernel it works fine. With the 4.15.0-21 (lp1770003+build.1)
kernel the system boots without any SAN disks discovered. I will attach boot
logs for both cases, with qla2xxx extended error logging enabled. Since our
internal-built test kernel doesn't exhibit this problem, I have to think
something has changed in the set of patches being applied. We will need to
review the patch lists.

I can't tell what 'dpkg' command syntax is being used underneath, but I do see
this message in your output which indicates something is not quite right:
Removing linux-image-4.15.0-20-generic (4.15.0-20.21) ...
W: Removing the running kernel
W: Last kernel image has been removed, so removing the default symlinks
That suggests that this package is still replacing the normal kernel
instead of installing in addition to it. What is in /boot after your
install? Do you have two kernels or only one?

[Kernel-packages] [Bug 1770003] Comment bridged from LTC Bugzilla
--- Comment From dougm...@us.ibm.com 2018-05-10 14:31 EDT---
I know we didn't get notification yet, but I saw that "build.7" was on the PPA
so I tried to install it. I get the same results as before: errors from dpkg
and failed install, and the system is left in a crippled state where the
qla2xxx driver (perhaps others) loads but is not functional (cannot access the
SAN).
--- Comment From dougm...@us.ibm.com 2018-05-10 14:39 EDT---
I should add that I am *not* using "force" on dpkg when trying to install, and
yet the system seems to have been broken even though the dpkg command reported
an error.

I have had some luck reproducing this, on ltc-boston113 (previously unable to
reproduce there). I had altered the boot parameters to remove "quiet splash"
and added "qla2xxx.logging=0x1e40", and got the kworker panic during boot
(did not even reach login prompt). This was a fresh install of 18.04 -proposed,
with the 4.15.0-20.21 kernel. What is the status of the experimental patched
kernel?

Looks like it actually failed to install as well, so I'm looking at what
happened.

I would have expected this kernel to be installed along side the default

This was on a scratch install of 18.04 -proposed.
