  • The docks USB ports work right out of the box;
  • The docks Video requires graphics/drm-kmod;
    • In case you encounter kernel panic when loading the i915kms.ko module add the following to your /boot/loader.conf
kern.smp.disabled=1
  • Wireless seems to work with this settings added to /boot/loader.conf:
if_iwm_load="YES"
iwm8265fw_load="YES"    
  • Suspend/Resume seems to work from X, if you disable TPM in the BIOS/UEFI;

Updating the firmware is possible after converting the ISO image to a bootable .img to use with an USB stick, using sysutils/geteltorito:

# geteltorino -o bootable.img bootable.iso

Overall impression so far: Good, would recommend to current-running hackers.

Untested: Camera, Microphone, Fingerprint reader, Smartcard reader, SD-card reader.
