At least before the system didn't hang.

Now I've just booted with a differently configured kernel,
with only about half of the debug flags turned on.
This one resumes from suspend, and *with* working USB too.

Ugh. Gotta love it when the bug is so subtle that turning on
the debug flags makes it (1) get worse, and/or (2) get cured.

Here's the abbreviated diff between broken (no USB on resume, no hang),
and working (good USB, no hang) .config files.
..
-CONFIG_RTC_CLASS=y
+# CONFIG_RTC_CLASS is not set

Mmm.. also had the RTC conflict resolved in that one.
Time to try another kernel with just the RTC change now.
..

Okay, that might be it. I've booted and am running without debug flags again.
The difference between "bad" .config and "good" .config was this (below).

Could somebody please fix the RTC mess in kconfig now ?
