Solved System freezes on reboot only

I just got a used thinkpad x1 yoga first gen on eBay. The condition is fantastic but when I reboot the bios freezes. This only occurs in reboot. Does anyone have any idea why? I am wondering if this is a freebsd issue or something else but I’m not certain. If you guys have any suggestions please let me know. It is a fresh install barebones. I’ve already tried installing the drm-Kmod to no avail. I will let you know how disabling powerd goes tomorrow. Any help is much appreciated. Thanks.
 
Does that only happen when rebooting from FreeBSD? You could try booting another OS (e.g. Linux) from a USB stick and check if the same happens when rebooting.
My guess is that this is a BIOS bug; maybe it fails to re-initialize a piece of hardware correctly.

The usual thing to try: is the bios / uefi update to the latest version available? If not, update and see if that fixes the problem.

Ok I updated the bios but it still freezes upon reboot. I also installed all the latest freebsd updates. Im on 12.0 release patch 10. Any other pointers?
 
On this blog post (on a t480) having bluetooth enabled caused hanging on reboot. Try disabling it. Moreover TPM can give problems too: try disabling it if you have problems with suspend/resume or the OS reports errors (in my case about a USB port) only at reboot.

Yes, I already replied on your status before seeing the post, and it's indeed the intel wifi/bluetooth combo -- we don't have the firmware (yet) for bluetooth part, driver fails to attach and likely gets the device in some weird state, making the BIOS hang on reboot when it goes over the devices. Note that cold reboot helps.

Disabling Bluetooth indeed worked! I had saw that post and it was my next step so when you guys brought it up I was eager to try! I'm so glad it works now. Thank you all very much!
 
I see that firmware loader for these bluetooth parts just landed in -CURRENT, with MFC reminder, so we'll likely get it working in 12.1.
