Hello Jeff,

Have you heard back from the dev team?

Do they confirm that an issue involving missing MSA_READY notifications
was ever noticed?

What devices were affected? (All msm8998? A subset of msm8998?)

Was the issue eventually fixed?
(Probably fixed, otherwise newer devices would be affected)
