Well it seems that it's the omap4_finish_suspend in this series that
can be used to trigger the bug, although the bug has been around for
few years. So then instead of mentioning random hangups you can have
a better description with something like "Patch xyz added PM idle
support for omap4, however bug 123 causes so and so. Fix the issue
with blah blah".

Also, if you have some easy way to reproduce the bug maybe mention
that too? That would make it easy to verify if issue has been fixed.

Regards,

Tony
