Internet disconnected unexpectly + Xorg freeze while watching html5 video in Chrome

[Mike Gao]

A few issues:

1)With Intel(R) Wireless-AC 9560, under kernel 5.4 for Ubuntu 20.04.1, the system sometimes gets disconnected with the network and I get the following error in syslog:

iwlwifi: BIOS contains WGDS but no WRDS

It is unclear if this is the cause of the problem, but this is likely related to kernel.

2) Watching HTML5 videos on Chrome with Nvidia GPU (440 driver) will sometimes cause xorg freeze. The exact cause is unknown. (Mouse, control all freeze for 5-10 seconds)

3) After Wake up from sleep got the following error on screen

sof-audio-pci error: no reply expected, received 0x0
iwlwifi: BIOS contains WGDS but no WRDS

4) After wake up from a long sleep session, sometimes chrome will not render web page correctly or even freeze. It is unclear if its a Chrome problem, or a Nvidia problem, or a Kernel Problem.

This is what happened after waking up from a long sleep.

hi Mike
Could you simply "apt install linux-oem-5.6" instead!?
Then check the issue again.
Thanks

[Mike Gao (mikegao)]

Hi,

The iwlwifi issue is still there, and complete xorg freeze still happens, but less frequently. What's the difference between 5.6 and 5.4 kernel?

I thought 5.4 should be LTS? May be the fixes are already incorporated in the upstream kernel updates? When are we going to have kernel updates to 5.4.66?

[koba (kobako)]

@Mike,
Are the point 2&3 gone!?
please also cat /proc/cmdline?!

[Mike Gao (mikegao)]

No. Same issue still happens. I'm now back to the LTS kernel, which received an update BOOT_IMAGE=/boot/vmlinuz-5.4.0-48-generic with nvidia driver 450

The same issue still exist, and I think it got even more severe. Chrome will freeze even opening a new tab some time. Also the gnome animations are really really laggy, which could be a bug but I'm unsure if its ubuntu related. Still, I didn't have such issue on Fedora.

[koba (kobako)]

1. Did you connect with 2.4g or 5g!?
2. Only play html5 on chrome can trigger the issue!? Did you ever try Firefox!?
3. please prime-select intel & reboot, try

[koba (kobako)]

@Mike,
I tried Firefox,
both nvidia&intel gpu are fine after resume from suspend.
For chrome, the issue would be triggered with nvidia.

[Mike Gao (mikegao)]

@Koba,

You're right, it doesn't happen on Firefox. This only happen on Chrome. But its a bit weird since it does not happen on fedora.

I connected with 5g, but happen with 2.4g too. Would you like some logs?

[koba (kobako)]

@Mike,
I also tried chromium and the issue still can be triggered.
Would you please file a bug to chromium first !?
https://bugs.chromium.org/p/chromium/issues/list

[koba (kobako)]

@Mike,
For wifi issue, could you help to turn off the power save of wifi and check it again.
#Setting->Power->Wifi(wifi can be turned off to save power)

[Mike Gao (mikegao)]

I don't think that the powersave feature. When I turned it off the wifi just got disconnected.....

[Mike Gao (mikegao)]

Yes, I'll submit a request to chromium as well and paste the link here

[koba (kobako)]

Do you know what kind of chipset is your wifi ap or could you share you model of wifi ap!? e.g. Broadcom, Realtek?

I have a same machine as yours and can't simply trigger the issue 1.
Could you dump the dmesg to me when the issue 1 is triggered!?
Please also cat /proc/cmdline

[koba (kobako)]

Could you also grep the wifi firmware version!?
#dmesg | grep iwlwifi.
e.g. iwlwifi 0000:00:14.3: loaded firmware version 12345

5.4.0 LTS kernel, Ubuntu official

[Mike Gao (mikegao)]

There's also the issue with this
Sep 24 05:47:59 MikeBook kernel: [124673.965170] sof-audio-pci 0000:00:1f.3: error: no reply expected, received 0x0

I don't know if you know what caused this.

[Mike Gao (mikegao)]

I think the chipset for my ap is realtek, but not 100% sure. Theres no information on it that I can find online - I can check with my provider if necessary, but this level of constant connect/disconnect doesn't happen with my mac or even on windows (same machine, boot from another drive)

[koba (kobako)]

@Mike
for the audio error message, does this cause any function issue!?
On my side, i also get this message.
for the wifi issue, could cat the whole dmesg to me once the issue is triggered.
The wifi issue can't be triggered on my side.

[Mike Gao (mikegao)]

Sure. I'll send dmesg to you once the issue is triggered.

The audio doesn't cause function issue. The only problem is that sometimes volume control keys don't work but I doubt if its related to the error. I just think since it's a LTS version, might as well submit patches that fix the audio error message as well?

[Mike Gao (mikegao)]

Hi,

The wifi disconnect happened again today.

I dmesg'ed while it happened. attached below

@Mike,
could you help to try the mainline kernel(5.9)!?
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9/

[koba (kobako)]

if the issue still can be triggered, please also dump the dmesg...
i noticed one alarm.

Yeah, more internet problems.. This is on the latest kernel (5.4.0-51-generic)

[Mike Gao (mikegao)]

I got another wifi shutdown today, and therefore I'm moving to Fedora 33 with the latest kernel. Please close this issue.

I have also attached the dmesg message below.

[koba (kobako)]

@Mike, sorry Im busy on others.
Because can't find the kernel version in the last logs.
Did you try the mainline kernel!? and is the issue triggered again!?
