KTR ?

Hi,

FreeBSD 7.0-CURRENT (LSD_SMP) #0: Sun Jul 16 10:39:02 CEST 2006

daffy_at_gw:~ %> sysctl debug.ktr                                         
-[11:21]-
debug.ktr.alq_enable: 1
debug.ktr.alq_file: /tmp/ktr.out
debug.ktr.alq_depth: 32768
debug.ktr.alq_failed: 0
debug.ktr.alq_cnt: 0
debug.ktr.alq_max: 0
debug.ktr.clear: 0
debug.ktr.version: 2
debug.ktr.entries: 32768
debug.ktr.compile: 536871424
debug.ktr.mask: 1
debug.ktr.cpumask: -1

/tmp/ktr.out is empty & nothing is printed out on console when  
alq_enable is set to 0.
Is does not work neither with UP nor SMP kernel. What am I missing ?

Best regards,
