Dear Maintainer, I confirm this issue. I experienced it with an AMD R7 240 graphics card[1] on a regular Debian Sid host running kernel 6.6.15. Booting with the previous kernel (6.6.13) did not change the situation but I confirm "Accel" "no", as suggested by Grégory, is a suitable workaround.
The machine that experiences this issue idles most of the time, so let me know if I can do/provide anything that would help solving this. Cheers, -- Xavier G. [1] lspci: Advanced Micro Devices, Inc. [AMD/ATI] Oland PRO [Radeon R7 240/340 / Radeon 520]
