Hi Borislav, Arnd Bergmann sent a patch regarding this issue on x86 that I merged several weeks ago. https://lore.kernel.org/lkml/20240719075454.3595358-1-arnd@kernel.org/ https://lore.kernel.org/all/c3d0757a-07c0-4f83-9f06-c3ad205aa1e9@foss.st.com/ > > People love to do > > depends on ...

Do you have the above fixup in your tree ? If not please try it. Thanks, Regards, Raphaël > > that COMPILE_TEST thing is forcing me to simply blacklist it and is not really > helping. > > Thx. >
