[Impact]
The Ubuntu-4.4.0-120.144 kernel (now in -proposed) fails to boot on
all arm64 hardware: no console output or any other sign of activity,
the system freeze just after the bootloader loads vmlinuz, and jumps
to it.
We first experienced it on the snapdragon kernel snap in -beta
(dragonboard 410c) but the bug is arm64 generic, and it affects all
the arm64 hardware: a thunderx board shows the same exact symptoms.
The regression came down as part of the 4.4.115 stable update
("79e83d1 bpf: introduce BPF_JIT_ALWAYS_ON config") and enabled this
option that crashes the arm64 kernel on boot.
[How to test]
Apply the attached patch, recompile, install and boot.
[Regression potential]
None, since the kernel already fails to boot.

[Kernel-packages] [Bug 1763644] Re: Ubuntu-4.4.0-120.144 fails to boot on arm64* hardware
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 the problem still exists,
change the tag 'verification-needed-xenial' to 'verification-failed-
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!

We first experienced it on the snapdragon kernel snap in -beta
(dragonboard 410c) but the bug is arm64 generic, and it affects all
the arm64 hardware: a thunderx board shows the same exact symptoms.
The regression came down as part of the 4.4.115 stable update
("79e83d1 bpf: introduce BPF_JIT_ALWAYS_ON config") and enabled this
option that crashes the arm64 kernel on boot.
[How to test]
Apply the attached patch, recompile, install and boot.
[Regression potential]
None, since the kernel already fails to boot.

[Impact]
The Ubuntu-4.4.0-120.144 kernel (now in -proposed) fails to boot on
all arm64 hardware: no console output or any other sign of activity,
the system freeze just after the bootloader loads vmlinuz, and jumps
to it.
