Description Arun Sharma 2003-02-08 06:40:06 UTC

	Enabling mutex profiling panics the kernel.

Fix: 

The problem is caused by holding the mprof_mtx and calling
	printf, which results in a blockable malloc().
How-To-Repeat: 	# sysctl debug.mutex.profiling.enable=1
	# sysctl debug.mutex

Does this problem persist?  I think other people are 
successfully using mutex profiling thesedays.
