So, let's be honest about why this bug isn't being fixed then.  Your
attitude to this problem is ignore it and to do nothing, rather than
trying to fix it via a perfectly good transition path provided for
you.

Okay, now we can see clearly why the bug is still there.  Thanks.

Given such an attitude, remind me why I should care whether iMX breaks
while we do the consolidation and cleanup work to core code, such as
the recent restart changes.
