Hi,
I'm happy to report the kernel boots with these new patches. 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.
