- I can almost resume it from RAM with "Security Chip" ("TPM") disabled
in the BIOS setting. Except display remains off. With TPM enabled,
I couldn't power on the machine after suspend to RAM.

- Disabling TPM doesn't help hibernation.
- I tried disabling various devices (iwm, em, xhci, ehci, ...). Didn't
help instability of hibernation.
- Most failures are not recognizing hibernation (`/ was not properly
unmounted')
- Unhibernation succeeds when you are really lucky. :)
