# It's been a busy month with dock issues! Two specific kernel constraints:
# 1. We're, for the moment, stuck on the LTS kernel because kernels >6.15.?
# break wired networking on the dock. This has been reported in Fedora
# fora:
# https://discussion.fedoraproject.org/t/fedora-42-driver-issues-with-kernel-6-15-thunderbolt-docking-station-igb-usb/157039
# 2. "drm/dp: Change AUX DPCD probe address from DPCD_REV to LANE0_1_STATUS"
# (included in 6.12.44, so we're pinned to one release earlier) breaks
# external DisplayPort displays on the Thunderbolt Dock. Issue tracker:
# https://gitlab.freedesktop.org/drm/amd/-/issues/4500
# A patch has been developed as of 2025-09-03, but no fix yet. Also
# believed to be broken in 6.16.0 and newer.
# via https://discuss.cachyos.org/t/thunderbolt-dock-dp-displays-no-longer-working/14695/2
