there might be something wrong with driver, can you provide serial log with no_console_suspend? or using rtctrace
Who are you?

The hibernation image is stored successfully, that means drivers work ok.
Well, not entirely necessarily.  We execute the ->poweroff callback for all
of them in the last step, maybe one of these hangs.

You can verify that by adding a reboot trigger after the dpm_suspend_end()
invocation in hibernation_platform_enter().  If it triggers 100% of the time,
drivers are OK.
Serial console... might be fun to set up, but might help, right.

Hi!

On thinkpad X60, if I hibernate in platform mode, it does not power
down, but I get black screen, moon icon blinking, and CPU fan running
(CPU probably too).

I can hold the power button down to force powerdown... if I notice
what is going on before the battery is empty.

Any ideas what could be wrong there?
Not right away.

Have you tried any previous 4.1-rc kernels?
Yes, and it was broken there, too. It is possible that 4.0 is broken,
too, I did not use hibernation for some time.

3.14 kernel works ok. I'm trying v3.19 now.
I see.

OK, it would be good to narrow down the time frame when it broke.

Thanks,
Rafael
