When the error is on, running `sudo lshw` causes the program to hang:

I can confirm this issue in 20.04 linux-image-5.4.0-42. This message
only appear for my usb3.1 gen1 type-c hub when it is connected on boot.
If I re-plug the hub after boot, the message stops. It doesn't appear
for another connected usb3 type-a hub.
In /var/log/syslog, it prints every 4 seconds:
I am using thinkpad x220 with osuse 12.1 and kernel 3.1.9 and 3.2.4.
Both kernel versions have random freeze (SysRq keys don't work) that
needs hard reset. Previously used osuse 11.4 and didn't had this
problem. Nothing usually is running when the freezes happen.
I have Ethernet controller: Intel
