[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Travis Johnson]

it seems the fix is in proposed according to this page:
https://launchpad.net/ubuntu/+source/linux. But when I enable the
proposed repository the version there is old, so the version on that
page must just be the source version, but the package hasn't actually
been put in the repo?

Clearly I don't understand how this proposed/update/release process
works. I'd love to be able to install this from proposed and bake my own
base AMI.

I'm going to find time to poke in IRC and see if someone can explain
this process/stages to me, but regardless I'd love to know a timeline or
at least where this sits in terms of priorities to be released (be it in
proposed or preferably updates).

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Andrey Kislyuk]

The Ubuntu 14.04 cloud images remain broken on m3.large and c3.large. Is
there a way to expedite building them with the fix? It seems that the
Ubuntu release process is broken, if bugs like this make it into the LTS
images and then don't get a clear timeline or priority for getting
fixed.

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Kamal Mostafa]

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!

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[JP Barbosa]

Hello,

I'm getting kernel panic on m3.large with these AMI:

- ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-20160420.3 
(ami-840910ee)
- ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-20160516.1 
(ami-13be557e)

"Kernel panic - not syncing: Attempted to kill init!
exitcode=0x000b"

Both use HVM. With Xenial paravirtual AMI I don't get kernel panic.

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Rasmus Larsen]

Well, they're probably waiting for the patch to hit the LTS kernel 4.4
branch, which will probably happen on the 18th May... Or something like
that.

But you can easily run it until then...

Use the 16.04 Beta 2 AMIs, but just disable kernel updates (say, with
"apt-mark hold") and update everything else. That will basically give
you all the final stuff, just without the last few kernel updates,
including the one that broke most EC2 instances.

When a working kernel gets here, just apt-mark unhold and you should be
good.

You might want to temporarily disable automatic security updates until
then if you do it though...

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Rasmus Larsen]

Kernel boots correctly on a c3.large with Thomas patch.

I've attached the output of the cpuid command (apt-get install cpuid) on
the instance, in case it has any interest.

** Attachment added: "cpuid command output c3.large"

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Joseph Salisbury]

I built a test kernel with the patch suggested by Thomas Gleixner.  The
test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1573231/

Can you test this kernel and see if it resolves this bug?

@Joe, based upon the identified commit, I wonder if it would be worth
testing backports of follow-on fixes specifically for that commit?

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b5d5f27d938fb6fc8d3202704e699d2694a02da6

Not sure if all of them are necessary but the second one esp. might be
relevant as it changes the divisor.

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Nish Aravamudan]

Err, apologies Joe, it does seem like upon more careful reading of the
bug report, the second mentioned commit (comment #18) specifically
introduced the regression? That seems unlikely at best given it's
contents, rights? That is, if the divisor was zero after that commit, it
was zero before it, too, unless there's another division going on that's
implicit.

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Rasmus Larsen]

I can confirm that I can boot with this kernel on a C3.large instance.

If anyone else wants to verify this, the procedure is to boot one of the
failing instances with the Beta 2 AMIs and install the build (and
reboot).

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Joseph Salisbury]

I built a test kernel with a revert of 1f12e32f4. To revert this commit,
I also had to revert e7ee3e8, 2d4de83, 87f01cc and 33c3cc7

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1573231/

Can you test this kernel and see if it resolves this bug?

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Rasmus Larsen]

I get the same issue with the build, which seemed weird so I retested and it 
looks like I must have mislabeled one of my builds, because now when I build 
31c2013e4ea2e594522980acc3d20e88664b19f1, I still get the issue, but if I go 
back to a6ebb4464659d35e0516900a8493f9720dd77d67 it works.
Somehow I must have swapped some builds...

a6ebb4464659d35e0516900a8493f9720dd77d67 Good
31c2013e4ea2e594522980acc3d20e88664b19f1   Bad
8ae10f463b7ae3455e9d0507176349c76580995f   Bad

Really sorry about the detour Joseph.

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Joseph Salisbury]

I built a test kernel with a revert of 33c3cc7(8ae10f463 in Xenial).  To
revert this commit, I also had to revert e7ee3e8, 2d4de83 and 87f01cc.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1573231/

Can you test this kernel and see if it resolves this bug?

commit 8ae10f463b7ae3455e9d0507176349c76580995f

perf/x86/mbm: Add Intel Memory B/W Monitoring enumeration and init

BugLink: http://bugs.launchpad.net/bugs/1397880

The MBM init patch enumerates the Intel MBM (Memory b/w monitoring)
and initializes the perf events and datastructures for monitoring the
memory b/w.

Its based on original patch series by Tony Luck and Kanaka Juvva.

Memory bandwidth monitoring (MBM) provides OS/VMM a way to monitor
bandwidth from one level of cache to another. The current patches
support L3 external bandwidth monitoring. It supports both 'local
bandwidth' and 'total bandwidth' monitoring for the socket. Local
bandwidth measures the amount of data sent through the memory controller
on the socket and total b/w measures the total system bandwidth.

Extending the cache quality of service monitoring (CQM) we add two
more events to the perf infrastructure:

  intel_cqm_llc/local_bytes - bytes sent through local socket memory 
controller
  intel_cqm_llc/total_bytes - total L3 external bytes sent

The tasks are associated with a Resouce Monitoring ID (RMID) just like
in CQM and OS uses a MSR write to indicate the RMID of the task during
scheduling.

I can still reproduce this in 4.6-rc5. See attached boot log.

I might do a bisect on this if I find the time...

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Rasmus Larsen]

I've tested with some instance types with the ami-3079f543 image (eg.
ubuntu 16.04 final with Ubuntu 4.4.0-21.37-generic 4.4.6)

The following instance types fail to start with a kernel panic:

r3.large
c3.large

The following instance types seem to work:

t2.micro
c4.large
m3.medium

I haven't tested with all sizes, but I suspect all t2, c4 and m3
instances are good.

[Kernel-packages] [Bug 1573231] Re: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do-release-upgrade -d

[Rasmus Larsen]

Currently also encountering this issue (the same kernel panic) with ami-
3079f543 on eu-west-1 with a c3.large instance.

So this seems to be a general ubuntu 16.04 on AWS issue and not an
upgrade specific issue. I haven't seen this issue with the beta2 AMIs.

Interestingly I seem to be able to start the AMI on t2.micro instances,
so this could well be instance type specific.

[Will Buckner]

Sorry, I don't think there's any possible way to do it. The machine
won't boot. I could try to reproduce the issue again on a different VM,
but I still wouldn't be able to collect logs.
