[All] Black Screen of Death - Won't resume from standby

[Steven **]

I've seen this several times with SHR-Unstable and now with Android.
So, I'd say it's something that is common among these distro's.  Is it
seen on all distros?  Is it the kernel?  Hardware bug?  Bootloader
issue?
Any clues how to debug this or what might cause it?

I know I'm not the only one that sees it.  How are others dealing with
these random lock-ups?

Thanks,
Steven
