Message:

automatic kernel console lockout

• kernel automatically relinquishes the access to the kernel console when the uspace maps the respective physical memory area
• kernel output before uspace initialization is currently broken on Ski (no physical memory area), but this is pending further unification
• kernel console devices are now independent (there is no system-wide "silent" variable), thus on multiple devices the kernel console and uspace output might be usable at the same time
