Hmmm, I am testing with straight-up .37-rc1, c8ddb2713c62. It does not
include your patch.

This time around, still running -rc1, I ran pm-suspend and it suspended
+ resumed fine. The second time I ran pm-suspend, it switched to text
console and started flashing the moon LED, but hung there with the LCD
backlight still on and the LED moon flashing.

So, definitely something exciting going on... and not a simple
suspend regression, and definitely not caused by this patch, my
apologies. Subject line updated accordingly.

I'll try applying "Autodetect itpm devices" and report back.
