Hmm.. suspend/resume are fine on Nokia N900 with and without the patch.
Patch also didn't fix the idle retention.

Sorry not being verbose enough, I was testing the idle retention.

For me it looks these differencies are explained by different
bootloaders. As Kevin told they may leave MUSB in a wrong state. Was it
so that before hwmod conversion the musb did IP reset etc and now this
feature is missing? So I'm thinking is this problem a regression or
missing feature after hwmod conversion?
