When plugged in, the dock works fine, except no USB devices are recognized. After some googling I found that I need to authorize it access to the dock via sysfs https://lkml.org/lkml/2017/5/18/848 After I run echo 1 > /sys/bus/thunderbolt/devices/0-1/authorized I can take full use of the dock, however if I unplug it, I face a kernel bug at: drivers/pci/msi.c:352 (dmesg attached). This is the free_msi_irqs function, but I don't understand the code. Any explanation/help suggestions?
