Hi Kai-Heng~
I sent the mail as you requested to the kernel module maintainers you
mentioned above.
Cheers,

Title:
realtek
Hello Kai-Heng,
I edited the .config file in wireless-drivers-next and manually added
the RTW88 drivers you mentioned above and then rebuilt the 5.3.0-rc1+
kernel.
After rebooting into the new kernel, I noticed that rtw88 and rtwpci
kernel modules are now loaded but wifi is still not working...
Hi Kai-Heng,
I checked my /etc/modprobe.d/blacklist.conf file, however, rtwpci and
rtw88 are not blacklisted. I am not sure why both these kernel modules
are not loaded when booting with kernel 5.3.0-rc1+...
Should I try building 5.3.0-rc1+ with different options?

Hi Kai-Heng~
Thanks for the help. Now the 5.3.0-rc1+ kernel with wireless-drivers-
next builds properly. I rebooted into the new kernel (selected from GRUB
menu) and I can verify that wireless does not work.
I have attached a tarball containing the output of dmesg, journalctl
-b0, and lsmod on
Hi Kai-Heng~
I tried the steps mentioned in #24 to build a kernel with the latest
wireless-drivers-next modules. However, I'm getting the following error
at the last step:
$ INSTALL_MOD_STRIP=1 modules_install && sudo make install
modules_install: command not found
Is there anything else I need
Hi Aaron,
> rtw88 is not working on 5.3-rc2 too.
> right?
That is correct. rtw88 is not working for me on 5.3-rc2 mainline kernel.
I will try to build a kernel with wireless-drivers-next as suggested in
#24.
And for the time being I will add rtw88 to my
/etc/modprobe.d/blacklist.conf and
btw I can confirm that viot's workaround in #19 does indeed work on
5.0.0-23-generic which was released from the disco dingo repos
yesterday.

Hi Aaron~
I removed r8822be from the blacklist, rebuilt the mainline kernel with
sudo update-initramfs -u -k 5.3.0-050300rc2-generic
and rebooted. What is interesting is that in mainline, r8822be is not
loaded at all! I have attached journalctl -b0.
In future kernels, will the Realtek 8822be
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
Hi Aaron~
I have attached the debug info you requested for #16.
This time I re-blacklisted r8822be driver in blacklist.conf and removed
rtwpci from blacklist.conf, rebuilt initrd, rebooted, and used the
rtw88.debug_mask=0x3ff option in linux cmdline in GRUB.
As expected, wifi is not working
Hi Aaron~
For #10 and #11, I removed r8822be from /etc/modprobe.d/blacklist.conf
and added rtwpci to blacklist, rebuilt the initial ramdisk with sudo
update-initramfs -u -k 5.0.0-21-generic and rebooted;
Now my realtek wifi card is operational with this workaround!
For the next test to help you
btw~
When I tried the workaround you suggested:
>1, append "blacklist rtwpci" in "/etc/modprobe.d/blacklist.conf";
>2, sudo update-initramfs -u -k 5.0.0-21-generic
and rebooted, wlp7s0 (wlan0) does not even show up anymore. I have
attached the output of lsmod when workaround 1 and 2 are
Hi Aaron,
I have attached the output of dmesg with rr8822be blacklisted and with
rtw88.debug_mask=0x3ff added to the linux commandline from GRUB.
After boot, I verified that the rtw88 driver is loaded:
junbuntu@pj:~/playground$ lsmod | grep rtw
rtwpci 24576 0
rtw88
Hi Aaron,
I appended r8822be driver to blacklist.conf and then manually ran "sudo
update-initramfs -u -k 5.0.0-21-generic" and rebooted. Still no wifi,
however.
I have attached the output of dmesg. BTW this notebook has Realtek
ethernet hardware, which is why kernel driver r8169 is loaded.
Hi Aaron~
I have attached a file containing the output of dmesg and lscpi from kernel
5.0.0-21
Please let me know if I you need me to provide add'l info.
Thanks,
Jun
