However I've run into an issue debugging early boot issues. Anything that causes the kernel threading system to die (for example here, a NPE) causes the boot console to halt before it outputs the error. Would it be possible to have both a kconfig option and a runtime option to toggle printk_fallback_preferred_direct()? Currently I've had to force it at all times while debugging. Thanks again for this amazing work! Very Respectfully, Peter Geis
