At the moment we can't fix/hint that the network-manager MISS in our ADT testing. The problem is that a new version of network-manager was published to updates and later reverted. That caused our automation to still expect tests with that version. I'm flipping the ADT task manually because of that.

Only 2 bugs remain unverified for this kernel:

1858815 PAN is broken for execute-only user mappings on ARMv8
1859522 use-after-free in i915_ppgtt_close

The first isn't easily verifiable and should just be ensured to not cause any regressions.
The second issue is unverifiable unless the kernel is rebuilt - so should have no risk on the kernel itself as it is.

After discussing with Tyler Hicks about the risks of those bugs, they are deemed non-risky to release unverified.

Manually setting the status of verification-testing to "Fix released"
