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.

With this option set, it will reboot after 10 seconds when that happens. This setting has been the default for trusty, where panic_timeout is 10. Later releases set it to 0. [Test Case] When booting a kernel, /proc/sys/kernel/panic should be 10. It's 0 for xenial, zesty and artful. After the fix, it's 10. [Regression Potential] For users that rely on the setting as 0, they will see their system reboot 10 seconds after a panic. They can set it back to 0 or other value. Though, on some rare cases, the system might not boot enough for this setting to be set. Balancing that with the case where kdump is used and the system is expected to boot, we expect the 10 seconds setting is okay. === For ppc64le, in some rare crash cases, kdump won't load unless timeout is greater than 0. Only 10 has been tested by IBM, so using a smaller value may not work.
