MISSING i386 result in this cycle: curtin bug 1768709

Still missing regression results for i386, setting regression-testing to 'Fix Released' so the release can proceed.

There are a few bugs that haven't been verified yet, however, they are mostly related to fixing hardware issue and have low regression potential. Given that, I'm setting verification-testing to 'Fix Released' so the release can proceed.

This bug was fixed in the package linux - 4.4.0-127.153
