Re: BUG [RESEND][NEW BUG]: kernel NULL pointer dereference, address: 0000000000000008

Hi Ma Jun,

Greetings again.

So, I just tested the recommended patch and the issue with the graphical login
screen was successfully resolved.

Thank you very much for your prompt reviews and recommended patches.

God bless.

Best regards,
Mirsad Todorovac

Hi Ma Jun,

Copy that. This appears to be the exact problem, and thank you for
reviewing the bug report at such a short notice.

I apologise for the wrong assertion.

The patch you sent then just triggered another bug, and it is not manifested without the patch (but a NULL pointer dereference instead).

But of course, it is not profitable to remove your patch and have
the NULL ptr dereference, but a proper fix is required.

Thanks again.

Best regards,
Mirsad Todorovac

Hi, Ma Jun,

Normally, I would reply under the quoted text, but I will adjust to your convention.

I have just discovered that your patch causes Ubuntu 22.04 LTS GNOME XWayland session
to block at typing password and ENTER in the graphical logon screen (tested several times).

This problem is not caused by my patch.
Based on your syslog, it looks more like a shedule issue.
I just saw a similar problem, please refer to the link below
https://gitlab.freedesktop.org/drm/amd/-/issues/3124

Regards,
Ma Jun
After that, I was not able to even log from another box with ssh, or the session would
block (tested one time, second time too, thrid time it passed after I connected before
attempt to login on XWayland console).

You might find useful syslog and dmesg of the freeze on this link (they were +100K):

https://magrf.grf.hr/~mtodorov/linux/bugreports/6.7.0/amdgpu/6.7.0-xway-09721-g61da593f4458/

The exact applied patch was this:

So, there seems to be a problem with the way the patch affects XWayland.

Checked multiple times the exact commit with and without the diff.

Hope this helps, because I am not familiar with the amdgpu driver.

Perhaps similar to the problem I encountered earlier, you can

Hi,

The last email did not pass to the most of the recipients due to banned .xz attachment.

As the .config is too big to send inline or uncompressed either, I will omit it in this
attempt. In the meantime, I had some success in decoding the stack trace, but sadly not
complete.

I don't think this Oops is deterministic, but I am working on a reproducer.

The platform is Ubuntu 22.04 LTS.

Complete list of hardware and .config is available here:

Hi,

Unfortunately, I was not able to reboot in this kernel again to do the stack decode, but I thought
that any information about the NULL pointer dereference is better than no info.

The system is Ubuntu 23.10 Mantic with AMD product: Navi 23 [Radeon RX 6600/6600 XT/6600M]
graphic card.

Please find the config and the hw listing attached.

Best regards,
Mirsad
