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
