Hi everyone!
I really don't know if this is the right place to post to inverstigate, feel free to indicate me a better place if needed.
So I'm currently trying to make the purple button of the Surface Pro 3 pen to work. It's working on bluetooth and I followed the bluetooth wiki page.
The first time I paired the device successfully and everything worked, except that the device wasn't automatically "mounted" (registered as keystokes only after pressing the button for 7 seconds to be in pairing mode).
In my attempt to investigate this issue, i removed the device using bluetoothctl in order to make step-by-step instructions for help on SurfaceLinux's reddit.
Then I rebooted and tried to pair again with the device. I connected to it and my computer instantly freezed.
Now I can't even repair my device back.
I'm giving you infos on my hardware and after the stacktraces got by journalctl.

NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [modprobe:3032]Do you know what can cause such a crash?
Does it keeps info somewhere on the old deleted bluetooth device that conflicts and do this bug?

The top "OOPS" (mutex_lock) is a bluetooth bug that was fixed in version 4.2 of the kernel:
Date: Mon Jul 20 20:31:25 2015 +0300
Bluetooth: Fix NULL pointer dereference in smp_conn_security
The l2cap_conn->smp pointer may be NULL for various valid reasons where
SMP has failed to initialize properly. One such scenario is when crypto
support is missing, another when the adapter has been powered on through
a legacy method.
The smp_conn_security() function should have the appropriate check for this
situation to avoid NULL pointer dereferences.
But they then made a change to that fix very recently in version v4.3-rc3:
Date: Fri Sep 4 12:22:46 2015 +0300
Bluetooth: Delay check for conn->smp in smp_conn_security()
There are several actions that smp_conn_security() might make that do
not require a valid SMP context (conn->smp pointer). One of these
actions is to encrypt the link with an existing LTK. If the SMP
context wasn't initialized properly we should still allow the
independent actions to be done, i.e. the check for the context should
only be done at the last possible moment.
My guess is that this first problem caused the other "OOPS" in your log after things went wrong.

Ok, so it's normal if I have this bug.
As I followed the bluetooth's arch wiki page, I created a udev rule to power up my device automatically, and I think this rule is triggered too soon inside the boot process.
Removing the udev rule make it able to pair without crashing.
Thank you for the help, I will try to compile my own 4.3 kernel for the fix (or ask the AUR package maintainer to update).
