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-
artful' to 'verification-done-artful'. If the problem still exists,
change the tag 'verification-needed-artful' to 'verification-failed-
artful'.

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!

This is documented and fixed by mainline commit:

x86/xen: Reset VCPU0 info pointer after shared_info remap

This patch fixes crashes during boot for HVM guests on older (pre HVM
vector callback) Xen versions. Without this, current kernels will always
fail to boot on those Xen versions.

Sample stack trace:

During boot, the HYPERVISOR_shared_info page gets remapped to make it work
with KASLR. This means that any pointer derived from it needs to be
adjusted.

The only value that this applies to is the vcpu_info pointer for VCPU 0.
For PV and HVM with the callback vector feature, this gets done via the
smp_ops prepare_boot_cpu callback. Older Xen versions do not support the
HVM callback vector, so there is no Xen-specific smp_ops set up in that
scenario. So, the vcpu_info pointer for VCPU 0 never gets set to the proper
value, and the first reference of it will be bad. Fix this by resetting it
immediately after the remap.

[Bug 1771679] Re: Kernel panic on boot (m1.small in cn-north-1)

[Kamal Mostafa]

Some more data points:

An m1.small instance running a Xenial AMI (with linux-aws-xenial) works
fine in cn-north-1.

An m1.small instance running the same kernel works fine in us-west-2.

The Xen hypervisor version for m1.small in cn-north-1 differs from us-west-2:
us-west-2:
[0.00] SMBIOS 2.7 present.
[0.00] DMI: Xen HVM domU, BIOS 4.2.amazon 08/24/2006
[0.00] Hypervisor detected: Xen HVM
[0.00] Xen version 4.2.
cn-north-1:
[0.00] SMBIOS 2.4 present.
[0.00] DMI: Xen HVM domU, BIOS 3.4.3.amazon 11/11/2016
[0.00] Hypervisor detected: Xen
[0.00] Xen version 3.4.

[Bug 1771679] Re: Kernel panic on boot (m1.small in cn-north-1)

[Dan Watkins]

We've only seen this on m1.small instances, but we haven't tested
exhaustively (we do know, though, that m3.large is fine).

The command used to create the instance was:

aws --profile=china --region=cn-north-1 ec2 run-instances --key-
name=Odd_Bloke --image-id=ami-8fcd13e2 --security-groups philroche-ssh-
only
