Alright, after a new bisect run I got a different result, so I most
likely did something wrong the first time.
ff3468ac94597efdcbc56f372528dfc98b114dac is the first bad commit

Provide userland notification of gpio pin changes ("userland
gpio interrupts").
Maybe more likely this is causing the panic?
Doesn't make sense :-(
Can you try to fetch the latest 13-current as of now and re-build
the kernel? I noticed some issues myself which got fixed.
I did that, still panics the same way.
But, the commit above is about gpio, and I do have
'bytgpio_load="YES"' in my /boot/loader.conf
If I boot the kernel without that it works.
'kldload bytgpio' panics the machine.
Could you screenshot the panic backtrace after kldload of bytegpio ?
Sure:
