BT is stuck for 2 instance types but I don't think that should hold up this.

[Mehmet Basaran (mehmetbasaran)]

I will override the regression test results due to time constraints. Majority of the tests passed. I was able to hint most of the failed ones here: https://kernel.ubuntu.com/gitea/kernel/rt-hints/pulls/81 . The ones where I wasn't able to hint are:

ubuntu_overlayfs_smoke_test: Gives "cannot mount overlay read-only" accross all architectures. Doesn't look like a regression.
ubuntu_kselftests_ftrace:ftrace:test.d--event--subsystem-enable.tc, test seems to be flaky.

Need to overwrite ADT due to time constraints. Hints are here: https://kernel.ubuntu.com/gitea/kernel/adt-matrix-hints/pulls/36.

[Stefan Bader (smb)]

The VT setup is somehow not correct. It looks like this might be because the parent kernel released before the this one came to proposed.
