[Kernel-packages] [Bug 1872984] Re: RTL8822BE [10ec:b822] network driver rtl_wifi crashes on boot in Focal Fossa 20.04 - 5.4.0-21-generic and mainline 5.7.0-050700rc1-generic

2020-08-31 Thread George Mihai Lazu
Hello Kai.
After several reboots this morning I was convinced the issue would no longer 
reproduce. A couple minutes ago I have rebooted the system and the issue 
reproduced, and I was unable to get the wifi card working even though I have 
rebooted into Windows and back into Linux several times.

I have installed 5.9.0-rc1+ and tried rebooting again into Windows and
then Linux, this time successfully connecting to Wifi.

I will be updating you if the issue reproduces. Let me know if you need
any kind of logs that could help debug this issue.

2020-08-31 Thread George Mihai Lazu
Without testing the new kernel (I have 5.4.0-42-generic), I have tried
https://bugzilla.kernel.org/show_bug.cgi?id=206411#c11, and then booted
to Windows, connected to a network, and powered off windows with the
"Fast Boot" option disabled in Power Options.

So far, with several reboots, the wifi works correctly. I will be
updating you if the issue reappears, but so far this seems to be a good
fix for me.

2020-08-21 Thread George Mihai Lazu
@pe83 As of today, I am still experiencing these issues with a fresh install of 
Ubuntu 20 on a Lenovo Legion Y530-15ICH.
The only solution I see fit at this time is a downgrade to 19.

[Kernel-packages] [Bug 1872984] Re: RTL8822BE network driver rtl_wifi crashes on boot in Focal Fossa 20.04 - 5.4.0-21-generic and mainline 5.7.0-050700rc1-generic

2020-05-19 Thread George Mihai Lazu
I am experiencing the same issue on a Lenovo Y530-15ICH. After BIOS update, the 
issue seemed to no longer occur, however, it has now reappeared. 
I am currently running BIOS version 8JCN53WW (Dec 2019), the latest.
