Disabling CONFIG_HSA_AMD_SVM solved my problem. Now Radeon RX 6800 works fine on my ARM server (Hardware name: Think-Force Technology Universal Server/7140 Advanced, BIOS 1.1.7 20230216). Thank you so much. ------------------------------------------------------------------ Sender:Lang Yu <Lang.Yu@xxxxxxx> Sent At:2023 Jun. 9 (Fri.) 16:37 Recipient:彭逸豪 <pengyihao@xxxxxxxxxxxxxxx> Cc:alexander.deucher <alexander.deucher@xxxxxxx>; amd-gfx <amd-gfx@xxxxxxxxxxxxxxxxxxxxx> Subject:Re: Radeon RX 6800 does not work properly on Think-Force 7140 ARM server (generates Oops and causes system deadlock) Try to disable CONFIG_HSA_AMD_SVM in your kernel config.

After that, the GPU cannot be used normally, and the system is stuck in a "deadlock" state, and cannot log in normally after entering the user name. If the GPU is removed or replaced with another GPU such as an older Radeon RX 560, the system can log in normally.
