The stdout console implementations for minimal libc call directly into the various console drivers (depending on what specifc hooks are registered) causing faults when invoked from user mode. This happens, for example, when using printf() which eventually ends up calling fputc(). The proper solution is to ensure privileges have been elevated before the _stdout_hook is called. This was already done for printk(). puts() and fputs() have now been re-defined in terms of the fputc() and fwrite() functions, which are now system calls.
