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
