I am now running Ubuntu 20.04 with kernel version 5.4.0-37-generic and have reproduced the bug after running the command
# echo "file drivers/pci/* +p" > /sys/kernel/debug/dynamic_debug/control
as was requested. Attached is the dmesg log.
Attached to the Thunderbolt hub are an iphone and an external monitor. The connection drops a couple times over the period of the log.
