I am using the following system:

System Information
        Manufacturer: LENOVO
        Product Name: 21D4000HUS
        Version: ThinkPad Z16 Gen 1
        Serial Number: PF3XPEBD
        UUID: 59e137b9-fc54-11ec-80f2-6c2408eab813
        Wake-up Type: Power Switch
        SKU Number: LENOVO_MT_21D4_BU_Think_FM_ThinkPad Z16 Gen 1
        Family: ThinkPad Z16 Gen 1

It has the following graphics controller:

Advanced Micro Devices, Inc. [AMD/ATI] Navi 24 [Radeon RX 6400/6500 XT/6500M] (rev c3)

I see different bizarre AMD GPU errors from 6.2.0, 6.2.16, and 6.4.3. I have never been able to find a kernel that works 100% stable, so I am not sure how to narrow this down or work around it without some professional advice.

Here are the errors from Linux version 6.4.3-060403-generic (kernel@kathleen) (x86_64-linux-gnu-gcc-12 (Ubuntu 12.3.0-1ubuntu1) 12.3.0, GNU ld (GNU Binutils for Ubuntu) 2.40) #202307110536 SMP PREEMPT_DYNAMIC Tue Jul 11 05:43:58 UTC 2023.

When the errors happen, X / Wayland freezes up. The problem happens more often in Wayland than X, from what I can see. Sometimes, you can mode-switch to the TTY and try to recover some work, but other times it locks up any local interaction with the machine, so you can only get in via SSH. It does not seem to fully cripple the machine, but the machine usually refuses to complete the normal shutdown process when the infinite timeout message loop described below occurs.

I am not 100% sure what information would be most helpful for debugging this, but let me know and I will provide whatever is needed ASAP.
