It sounds like this might be the problem:
Bluetooth: Dropping L2CAP data: receive buffer overflow
in which case that would be a kernel bug. So this has been assigned to
the kernel.

Title:
Dualshock4 controller doesn't stay connected
Status in bluez package in Ubuntu:
New
Status in linux package in Ubuntu:
New
Bug description:
Pairing the Dualshock4 controller works somehow, after several
attempts. I expected this to work out of the box but it does not work
well at all.
Once the pairing is completed, if I try to connect it it doesn't stay
connected.
I have checked the dmesg and apparently there is a buffer overflow
somewhere.
I can pair a bluetooth headset to my laptop and the Dualshock4 pairs
with my samsung tablet without problems but when I try to pair the
dualshock4 to the laptop, running Ubuntu 19.10, it does not work.
Dmesg output:
