Reverting to 5.0.0-20 fixed wifi for me, this kernel doesn't load rtwpci module. I updated to 5.0.0-23 today, same problem as 5.0.0-21. I don't see any errors but wifi does not find networks.
I added debug_mask option to kernel command line and output journalctl -b0 is attached. I did not blacklist any modules. ** Attachment added: "rtlbug.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838133/+attachment/5280479/+files/rtlbug.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838133 Title: realtek r8822be kernel module fails after update to linux kernel- headers 5.0.0-21 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838133/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
