Title:
realtek r8822be kernel module fails after update to linux kernel-
headers 5.0.0-21
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Disco:
In Progress
Status in linux source package in Eoan:
Fix Released
Bug description:
=== SRU Justification ===
[Impact]
Realtek Wifi stops working after the driver changed from rtlwifi to
rtw88.
[Fix]
Sync rtw88 to upstream version, and use MSI on the device.
[Test]
User confirmed the backport fixes the issue.
[Regression Potential]
Low. Currently only 8822be uses rtw88.
=== Original Bug Report ===
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.
Best Regards,
Jun
