Yes it works, the problem is, even the bluetooth is disabled before
hibernate, it will be enabled after resume.

As Jeffery has put in comment #14:
"
With thinkpad_acpi blacklisted, Bluetooth is enabled on boot. I can't
turn it off unless I run "modprobe thinkpad_acpi" beforehand. After
turning Bluetooth off, I ran "rmmod thinkpad_acpi" before hibernating.
I verified that thinkpad_acpi isn't loaded (with lsmod) before hibernating
and after resuming. Bluetooth is enabled on resume.

I tried this same test with the acpi_osi="!Windows 2012" kernel
parameter (and thinkpad_acpi blacklisted). Bluetooth is disabled on boot.
I verified that thinkpad_acpi isn't loaded (with lsmod) before
hibernating and after resuming. Bluetooth is disabled on resume.

But I made a mistake in the comment, it's a S4 cycle, not a S3.

As Wouter has put in comment #12:
"
I also have trouble with this commit, it disables my hardware switch for
enable/disable wifi. See [1] for full explanation.

When I add acpi_osi="!Windows 2012" it fixes my issue.
