How did you upgrade to 21.10? (Fresh install / Upgrade) Upgraded from 21.04

Issue/Bug Description: I have a USB-WLAN adapter listed in lsusb as: Bus 001 Device 003: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

When it is connected, the system will crash a short moment after booting. It takes a bit longer when I do not log into gnome directly but switch to a tty. This happen son 5.15, on 5.13 the system is stable.

The following modules get loaded on 5.13 for the adapter:

lsmod|grep rtl
rtl8xxxu              139264  0
rtl8192cu              81920  0
