Hi Aaron~ I downloaded the mainline kernel 5.3.0 from the ppa you provided and installed as follows:
wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3-rc2/linux- headers-5.3.0-050300rc2-generic_5.3.0-050300rc2.201907281631_amd64.deb wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3-rc2/linux- image- unsigned-5.3.0-050300rc2-generic_5.3.0-050300rc2.201907281631_amd64.deb wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3-rc2/linux- modules-5.3.0-050300rc2-generic_5.3.0-050300rc2.201907281631_amd64.deb sudo dpkg -i *.deb I left my blacklist.conf unchanged (r8822be blacklisted, rtwpci not blacklisted). I rebooted and selected the mainline kernel from GRUB and added the rtw88.debug_mask=0x3ff linux cmdline option. But with r8822be blacklisted, wifi does not work even on mainline 5.3.0. I have attached the output from journalctl -b0. Here are the realtek kernel modules that are loaded: junbuntu@pj:~$ lsmod | grep rtw rtwpci 24576 0 rtw88 442368 1 rtwpci mac80211 847872 2 rtwpci,rtw88 cfg80211 708608 2 mac80211,rtw88 Should I try again but this time remove r8822be from blacklist.conf (and also do not blacklist rtwpci)? Best, Jun ** Attachment added: "journalctl -b0 output on mainline 5.3.0 kernel with r8822be blacklisted" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838133/+attachment/5280508/+files/rtwpci_rtw88_mainline_5.3.0_journalctl_b0.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1838133 Title: realtek r8822be kernel module fails after update to linux kernel- headers 5.0.0-21 Status in linux package in Ubuntu: Triaged Bug description: On July 24th I upgraded to the latest linux-headers-5.0.0-21 as part of the dist-upgrade for latest packages in Disco Dingo 19.04. I didn't notice that wifi was no longer working because at work I exclusively use a wired Ethernet connection. Today, however, when I tried to use my realtek r8822be wireless card, I discovered that it was totally unresponsive and did not work with wpa_supplicant / wpa_cli even when invoked manually from the command line (let alone with NetworkManager). When the problem occurred, I was using 19.04's latest kernel 5.0.0-21. I then rebooted and selected kernel 5.0.0-20 from GRUB menu. "uname -a" shows that I am using the previous kernel version: Linux pj 5.0.0-20-generic #21-Ubuntu SMP Mon Jun 24 09:32:09 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux With this kernel version as well as linux-headers-5.0.0.20, linux- headers-5.0.0-20-generic, my realtek wireless card works fine. While booted into 5.0.0-20 kernel, here are the realtek kernel modules that are loaded: # lsmod | grep r8 r8822be 692224 0 mac80211 806912 1 r8822be cfg80211 671744 2 mac80211,r8822be r8169 81920 0 Hopefully this realtek wireless regression can get fixed in the next minor kernel version. Let me know if you need any more information.
