Kernel BUG in paravirt_enter_lazy_mmu when running as a Xen PV guest
To mana
PVH is experimental and the hypervisor ABI is subject to change so I
wouldn't try making it work in a distro kernel.

Title:
Kernel BUG in paravirt_ente
As far as I can see, this should be part of 3.13.0-35.62 which is
currently in proposed. According to the SRU cycle this should go into
updates this week (possibly end of week). Unfortunately the changelog
has no reference to this bug report. The cloud images are iirc build
daily based on updates.
Is there an estimate for when this will hit release and cloud images? We
are blocked by this, and I don't see a reference to it in
https://launchpad.net/ubuntu/+source/linux.
Thanks.

Thanks David! I've queued up your comment #8 backport for v3.13-stable

Kernel BUG in paravirt_enter_lazy
Attaching a typical trace on one of our affected machines. This shows
the crash happening roughly 33 seconds after boot, which is where we
observe most of these. Some also happen much later after boot.

Thanks for the backport David. I build some test kernels with that and
put them to http://people.canonical.com/~smb/lp1350373/ (note that you
do *not* need linux-image-extra for ec2 installations). This should get
pulled in as stable patch but it would be even better if someone can
confirm the test
Raising the severity due to the impact on EC2.

We can confirm that we see a large fraction of our 14.04 Trusty Xen PV
instances exhibit a stack trace similar to the one referenced above in
paravirt_enter_lazy_mmu, followed by a crash.

Here is a working patch against 3.13.10.
** Patch added: "[PATCH 3.13.10] x86/xen: safely map and unmap grant frames
when in atomic context"
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1350373/+attachment/4167411/+files/0001-x86-xen-safely-map-and-unmap-grant-frames-when-in-at.patch
Thanks for the test kernel. Unfortunately it crashes in gnttab_init()
when booting. I think the backport to 3.13 is not correct.
I will try to produced a working backported patch.

I don't see that the patch landed in mainline as of yet:
x86/xen: safely map and unmap grant frames when in atomic context
As soon as it does, I can build a trusty test kernel with a cherry pick
of that commit and we can confirm it fixes this bug.
