You are using a custom ROM, please ask the ROM builder to contact us.
If anyone knows how to fix this, the issue will be reopened.

Looks like LOS team doesn't want anything to do with it either: https://gitlab.com/LineageOS/issues/android/-/issues/7545

Oh well...

I would say, their refusing is reasonable. Unless, we provide an evidence that prove the bug is related to LOS.

I agree. Unfortunately, we are at the mercy of the developers.

LineageOS is does not support root so we cannot get any support on their end. Is there any reason you believe it is an issue with the ROM? Something I can provide the devs there at-least? Right now we are at a dead end...

Also, I see another open issue with someone else using LineageOS and you tried providing support for their device? I don't understand why our issue is being dismissed when we are also on LOS..?

Without help from the ROM builder, troubleshooting the issue could be challenging. Can you get kmsg? #7390 uploaded kmsg so we know what happened.

@vvb2060 Hi, thank you for your support.

This is Unsuccessful boot /sys/fs/pstore/console-ramoops file after install Magisk Canary v27006
console-ramoops-0-magisk.zip

And this is successful boot /sys/fs/pstore/console-ramoops file without Magisk:
console-ramoops-0.zip

I'm ready to be a volunteer to install any modified Magisk file(s) to overcome this issue.

Device: Nvidia Shield TV 2019 Pro
OS: Lineage-21.0-20240805-nightly-foster (Android 14)

Thank you!

[vvb2060]

Don't use canary, install debug version and upload kmsg.

[hamedsbt]

@vvb2060
I've installed Magisk app-debug.apk (canary-27006), but after that, I couldn't boot Android successfully. So, I went to recovery and pulled the /sys/fs/pstore/console-ramoops file.
console-ramoops-0.txt

Also the result of dmesg > /sdcard/dmesg.log is:
dmesg.log

Finally, the result of cat /dev/kmsg > /sdcard/kmsg.log is:
kmsg.log

Note: result cat /proc/kmsg > /sdcard/kmsg.log is empty!

Are these okey?

Previously, bootloader used the skip_initramfs kernel command line parameter to decide which mode to boot into. For Android 10 devices, the bootloader MUST NOT pass skip_initramfs to the kernel command-line. Instead, bootloader should pass androidboot.force_normal_boot=1 to skip recovery and boot normal Android.

@vvb2060 I unpacked the boot.img file (magiskboot -h boot.img) I want to apply the two kernel parameters you mentioned to the cmdline of the header file. Could you confirm if the format is correct.
cmdline=androidboot.boot_devices=sdhci-tegra.0,tegra-sata.0,sdhci-tegra.3 skip_initramfs=0 androidboot.force_normal_boot=1

Thank you.

[hamedsbt]

@vvb2060 Thank you for your reply.
I can't understand C or C++ code clearly. Could you confirm if the format is correct please?
cmdline=androidboot.boot_devices=sdhci-tegra.0,tegra-sata.0,sdhci-tegra.3 skip_initramf=0 want_initramf=1 androidboot.force_normal_boot=1
Or
Can I patch the kernel file directly via magiskboot --hexpatch kernel 736B69705F696E697472616D667300 77616E745F696E697472616D667300 ?

Thank you.

@aviraxp Thank you for your help but I couldn't understand what you mean.

Hi, It's working. Thank you! I also attached the console-ramoops-0 file:
console-ramoops-0

[hamedsbt]

I installed this version of com.topjohnwu.magisk package from canary channel, but the device doesn't boot again!

[aviraxp]

The fix has to be reverted because it breaks more legacy sar + 2si devices. Pleaseet maintainer pick LineageOS/android_kernel_lge_sdm845@026011c into kernel instead.

[hamedsbt]

But unfortunately the maintainer said that he wasn't interested in applying any changes to support Magisk!

[hamedsbt]

@vvb2060 Do you update your version recently? Can I update magisk with your release? Thank you.
