Would it be possible for you to test a custom kernel built with the following commit applied on top and see if this resolved the issue you are seeing? https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=ba5ca5e5e6a1d55923e88b4a83da452166f5560e See https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#id-1.6.6.4 for instructions.
