Going soft? Nah, you know me. I never swear, so how could not swearing
cause me to go soft :-)


Perhaps a:

*********************************************************
** NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE **
** **
** trace_printk() being used. **
** Allocating extra memory for it **
** **
** This means that this is a DEBUG kernel and it is **
** unsafe for production use. **
** **
** If you see this message and you are not debugging **
** the kernel, report this immediately to your vendor! **
** **
** NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE NOTICE **
*********************************************************

Maybe that will work?
