Hello,

I installed Kali on a USB (persistence), I was using it for a while and everything was fine for a few sessions but now I cannot boot. When I boot it up it takes ages at the message:

IPv6: ADDRCONF (NETDEV_CHANGE): wlan0: link becomes ready
Then it shows the next messages (screenshot) and stays there for ever.

I suspect I caused this because I did:
1) Laptop connected with ethernet and on external monitor
2) Boot Kali - all good
3) Kali was running (ethernet + external monitor)
4) Unplugged HDMI cable
5) Unplugged ethernet cable
6) Connected to wifi - all good
7) Reboot

And now I'm stuck with this. Did I somehow mess the xorg config when unplugged the monitor cable while running? Did I also accidentally enable the delay on IPv6?

How should I approach this? Any help is appreciated, thank you.
