r8168 5.10.0-20-amd64 Debian KDE UI freezes and journal: eno1: esd_flag = 0x7bff ; eno1: cmd = 0xff, should be 0x07

[slrslr]

Hello,

5.10.0-20-amd64 Debian 11 (stable) with KDE desktop (5.20.5)

$ sudo inxi -Na

Network:   Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: N/A modules: r8168 port: N/A 
           bus ID: 03:00.1 chip ID: 10ec:8168 class ID: 0200
           Device-2: Realtek RTL8153 Gigabit Ethernet Adapter type: USB driver: r8152 bus ID: 3-4:3 chip ID: 0bda:8153 
           class ID: 0000 serial: 000001000000

(driver for device 1 not shown, because i ran inxi after removing it: sudo modprobe -r r8168;sudo apt remove r8169-dkms)

I have removed r8168 dkms because it repeatedly caused issue where computer UI (incl. mouse) was freezing every couple second with journal:

After unloading using modprobe as shown above, freezing stopped...
