I used the 5.12.0-rc1 kernel (commit 280d542f6ffac0) as a base. The full console log from the boot process is available at https://gitlab.com/-/snippets/2086833 in case you want to take a look. Note that there are some call traces starting around line 3220, but they are NOT introduced by these two patches and are also present with the base mainline kernel.
