Kernel Panic: Chromium Streaming Youtube Video on Jammy/Bullseye with kernel 5.15.40/41-flippy-73+o

[JFLim1]

Hi @ophub and other users,

I have been experiencing system freeze/kernel panic when streaming Youtube on Chromium on Jammy or Bullseye with kernel 5.15.40-flippy-73+o and kernel 5.15.41-flippy-73+o.

The system freeze can be random in the sense that sometimes after 10 minutes or 20 minutes of streaming Youtube video and other times I can stream for more than 60 minutes without any system freeze/kernel panic. This happen on both Jammy with kernel 5.15.40-flippy-73+o and kernel 5.15.41-flippy-73+o. and Bullseye with kernel 5.15.40-flippy-73+o.

The last system freeze/kernel panic have happen 30 minutes ago on Jammy-5.15.41-flippy-73+o

jfl@armbian:~$ cat /etc/ophub-release
VERSION_CODEID='ubuntu'
VERSION_CODENAME='jammy'
FDTFILE='meson-g12b-gtking-pro.dtb'
UBOOT_OVERLOAD='u-boot-gtkingpro-rev-a.bin'
MAINLINE_UBOOT='/usr/lib/u-boot/'
ANDROID_UBOOT='/usr/lib/u-boot/'
SOC='s922x-reva'
PACKAGED_DATE='2022-04-30'
KERNEL_VERSION='5.15.41'
K510='0'

I am wondering any other users on kernel 5.15.y experiencing system freeze while streaming video on Chromium?

You can update the kernels of 5.10/5.15/5.17/5.4 series and choose the one that suits you better.

I recently provided the /usr/sbin/armbian-kernel file in the firmware to support compiling the kernel in armbian. You can download this file to use. The kernel's selection configuration is further adjusted and optimized.

Hi @ophub,

Just a feedback and also wonder whether other users or yourself had experience this when streaming video using chromium (Bullseye) or chromium-browser (Jammy).

The advantage of using kernel 5.15.y-flippy is that I can boot on any of the USB Port on GT King Pro and it boot even when a HDD is also attached on the GT King Pro. With kernel 5.10 or 5.17 using u-boot.ext it can only boot on USB OTG Port and NO other drive attached. The downside with kernel 5.15 (without u-boot.ext) is the reported available RAM is 3.26GB instead of 3.70GB.

This system freeze/kernel panic when streaming video on Chromium is quite random but today it happen 3 times and yet right now I am streaming the same Youtube Video on Jammy-5.15.41-flippy-73+o -- now running for 1hr 22 minutes and still streaming.

Earlier it system freeze/kernel panic after 15 minutes. Not sure whether it is kernel issue or Chromium issue or just my particular Bullseye/Jammy installation issue. Since it happened 3 times today, I thought it might be a good idea to share.

Will test with kernel-5.17.7-flippy-73+ on Bullseye as I have installed this few days ago.

Hi @ophub

Update on Kernel Panic when Chromium stream video Bullseye-5.15..y-flippy-73+o. Date: 2022-05-20 Test video: https://www.youtube.com/watch?v=DQuhA5ZCV9M -- Duration: 3:00:37 (hr)

Bullseye-5.15.40-flippy-73+o dtb from kernel-5.15.40-flippy-73+o
Kernel Panic 2 times
-- First time happened around 20 minutes into streaming video
-- Secon time happened around 25 minutes into streaming video

Bullseye-5.15.41-flippy-73+o  dtb from kernel-5.15.41-flippy-73+o
Kernel Panic 2 times
-- First time happened around 32 minutes into streaming video
-- Secon time happened around 60 minutes into streaming video

Bullseye-5.15.41-flippy-73+o dtb from kernel-5.17.7-flippy-73+
Kernel Panic 2 time
-- First time happened around 14 minutes into streaming video
-- Secon time happened around 46 minutes into streaming video

Also Run same video on Bullseye-5.17.7-flippy-73+o using dtb from kernel-5.17.7-flippy-73+ Chromium can stream the whole video without issue (3:00:37 hr). This just one try so it might not be conclusive.

Based on this unscientific trial/test it looks like the kernel panic is repeatable and there could be an issue/conflict between Chromium and kernel-5.15.y-flippy-73+o.

I notice this on dmesg:
kernel-5.15.y-flippy-73+o
[    0.000000] Reserved memory: created CMA memory pool at 0x00000000c8000000, size 256 MiB

kernel-5.17.7-flippy-73+
[    0.000000] Reserved memory: created CMA memory pool at 0x00000000b8400000, size 896 MiB

I used the dtb from kernel-5.17.7-flippy-73+ on kernel-5.15.41-flippy-73+o and as highlighted above still kernel panic while streaming video on Chromium.

For the record, did not experience any kernel panic/system freeze on Bullseye/Jammy using kernel-5.15.40-flippy-73+o with Chromium on Web Surfing. Kernel Panic occur only when Chromium is streaming video.

Edit: 2022-05-21 Update Bullseye-5.17.7-flippy-73+o using Chromium to stream another 3hr+ video -- No system freeze issue.

Hi @ophub

Additional update: Bullseye-5.15.41-flippy-73+o Kernel Panic at 81 minutes while Chromium streaming video

Bullseye-5.15.41-flippy-73+o "sudo armbian-update 5.17.9" Bullseye-5.17.9-flippy-73+ So far no issue with Chromium streaming the same video over 170 minute.

Looks like there conflict (or cache issue?)between Chromium streaming video and kernel-5.15.y-flippy-73+o

Edit: Jammy-5.15.41-flippy-73+o Kernel Panic at 61 minutes while Chromium streaming video (Chromium Flags "--ozone-platform-hint=auto" enabled)

Ok, then you can use the 5.17 kernel for the time being. Yesterday, 5.18 was also released. Try it in a few days. In theory, the newer the kernel, the better the performance.

Thanks. Await and looking forward to the new kernel-5.18.

Looking forward to kernel-5.15.y-flippy being resolved to support Chromium Streaming Video.
