Bug Description

The linux-generic-lts-trusty meta package on Precise will give you:
  linux-base linux-headers-3.13.0-172 linux-headers-3.13.0-172-generic
  linux-headers-generic-lts-trusty linux-image-3.13.0-172-generic
  linux-image-generic-lts-trusty linux-modules-3.13.0-172-generic

And the kernel version returned from uname -a shows:
  Linux precise-testing 3.13.0-172-generic #1-Ubuntu SMP Sat Jul 6 10:46:56 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

This is breaking the automation as we're expecting the kernel version:
  3.13.0-172.223~12.04.1

It does appear for other series we include the ~12.04.1 bit in the uname -a output:

    Linux kowtow-b64 5.0.0-21-generic #22~18.04.1-Ubuntu SMP Thu Jul 4 17:25:00 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

But it is likely best to use /proc/version_signature in preference to this.

Andy suggest us to use "cat /proc/version_signature"

This command on this Precise node shows:
Ubuntu 3.13.0-172.223~12.04.1-generic 3.13.11-ckt39

This looks more reliable than the "uname -vr"

Testing a workaround on KT.

As we're just deploying P-ESM with KT

I think this will be fixed in the kernel, but as fix applied to the tool, marking this as fix-released.

Not sure if this should be "Invalid" for kernel itself. Re-open it.

This is affecting the SRU test this cycle with bug 1849079
