D3cold support has been a problem area, and there are some changes in progress [1] that could be related. Could you possibly collect the complete dmesg logs (with a recent upstream kernel, e.g., v6.4, if possible)? And the output of "sudo lspci -vv"? And the contents of /sys/firmware/acpi/tables/? You can attach them to the Debian bug report if that's convenient for you.
