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

[Mirsad Todorovac <mirsad.todorovac@xxxxxxxxxxxx>]

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).

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):

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.

Best regards,
