@timg-tpi: Got it! Thanks for the explanation. As I said, I've compiled
the kernel on my own, so don't worry :) But looks like a lack of testing
before the release

[Tim Gardner]

Grief - mainline only gets built when upstream Linux changes, hence the
reason for this stale config which we've since changed in the distro
kernel. I've requested a mainline rebuild which should complete
presently.

Seems that kernels in http://kernel.ubuntu.com/~kernel-ppa/mainline/ are
not fixed yet. I recompiled the kernel by myself with

As far as I can tell from the history here,
CONFIG_HARDENED_USERCOPY_PAGESPAN was responsible for the desktop not
coming up. Having the "rewind the stack before do_exit()" patch in
combination with that option prevented booting, becuase the usercopy
hardening created an oops that triggered the code paths affected by the
patch (but I'm still not sure what about that patch caused boot to
hang).

Thanks for the extra details Seth.

Can you say whether it's the second problem that was breaking the desktop
coming up on login?  IOW, I observed two problems.  One was a freeze during
the boot process, and the other was a freeze during the login process
(although the latter wasn't a total freeze, as ssh still worked).

[Kernel-packages] [Bug 1627198] Re: 4.8.0 kernels do not complete boot process on VM

[Seth Forshee]

I just wanted to add a note here to clarify things a little bit, since
from the comments here it's all a bit muddled. There are two loosely
related things happening.

The first problem, which is fixed by setting
CONFIG_HARDENED_USERCOPY_PAGESPAN=n, is that some security enhancements
were added in kernel version 4.8 related to copying memory from
userspace. One of these hardening features was to check for copies from
userspace which cross a page boundary, and when this happens the kernel
logs an error and terminates the running task immediately by causing it
to oops. This turned out to be too aggressive for now, because the
vmwgfx module is doing these sorts of memory copies from userspace.
Therefore when CONFIG_HARDENED_USERCOPY_PAGESPAN was enabled and the
kernel booted in VMWare Fusion, Barry was getting an oops.

This triggered the second problem. There's also a patch in 4.8 which
aims to make oopsing behave more reliably by calling do_exit() with a
clean stack, and this seems to be causing some sort of problems on
VMWare Fusion when the kernel oopses. The exact nature of those problems
isn't yet clear. Fixing the problem above side steps the problems caused
by this patch as it prevents the oops from happening, however I suspect
that the problem remains.

This config option is intended to be used only while trying to find
anything that copies from userspace with cross page boundaries, and it
looks like some vmware driver was doing exactly that.

I built the next test kernel, up to the following commit:
97433ea4fda62349bfa42089455593cbcb57e06c

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1627198

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

It looks like we'll have to perform a second bisect, but also reverting
commit 2deb4be2 between each step.

Let's start by testing v4.8-rc1 with commit 2deb4be2 reverted.  That
kernel is now build and available in the usual location:

Just to follow up, I was able to eventually gain a desktop with the rc1 kernel
and the bad commit reverted.  My current plan is to dist-upgrade to latest
yakkety, sans kernel packages, and you're going to build the rc2 kernel with
the revert.  Let's test that and see where we are.

That one gets a little farther but ultimately doesn't give me a desktop
either.

The previous kernels, once I logged in all I was left with was the lightdm
wallpaper.  With this kernel, the screen goes black, but that's it.  No
response on the desktop to mouse or keyboard clicks, but ssh works and htop
doesn't show any abnormal stats.

[Kernel-packages] [Bug 1627198] Re: 4.8.0 kernels do not complete boot process on VM

[Joseph Salisbury]

I built the next test kernel, up to the following commit:
2deb4be28077638591fe5fc593b7f8aabc140f42

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1627198

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

Title:
  4.8.0 kernels do not complete boot process on VM

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Yakkety:
  Confirmed

Bug description:
  On my native amd64 box, 4.8.0-15 works just fine, but on my VMWare
  Fusion 8.5 system, none of the 4.8.0 kernels complete the boot
  process.  I tried 4.8.0-15 from yakkety and 4.8.0-16 from yakkety-
  proposed.

  Currently  I am seeing the last message in my console at boot up as:

  [ OK ] Started Bluetooth service

  and then... it just sits there.

  Through the use of snapshots, restores, and package bisects, I've
  definitively narrowed it to linux-generic linux-image-generic and
  linux-headers-generic.

[Kernel-packages] [Bug 1627198] Re: 4.8.0 kernels do not complete boot process on VM

[Joseph Salisbury]

I started a kernel bisect between v4.7 final and v4.8-rc1. The kernel bisect 
will require testing of about 7-10 test kernels.

I built the first test kernel, up to the following commit:
1c88e19b0f6a8471ee50d5062721ba30b8fd4ba9

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1627198

Can you test that kernel and report back if it has the bug or not?  I
will build the next test kernel based on your test results.

Thanks in advance

All of these kernels (amd64, generic) boot successfully.

[Kernel-packages] [Bug 1627198] Re: 4.8.0 kernels do not complete boot process on VM

[Joseph Salisbury]

I'd like to perform a kernel bisect to identify the commit that
introduced this regression.  We need to first identify the last good
kernel version and the first bad one.  Do you know what kernel was the
last one that did not exhibit this bug?  If not, I can post some
download links, so prior kernels can be tested.

Unfortunately this kernel also fails to completely boot.  The last things I
see in the console are

[ OK ] Started Login Service.
[  36.445144] cgroup: new mount options do not match the existing superbock, 
will be ignored

I'll also mention that I see what looks like a crash in __wake_up_common.  I
see the Call Trace: but I can't scroll up on the console to get the details.

Hi Barry,

Could you re-test with the 4.8.0-17.19 kernel we have in ppa:canonical-
kernel-team/unstable

Thanks in advance.

Unfortunately, I cannot run this command on the system in question since
booting with the defective kernel never gives me a prompt or an ssh
