options         KTR_ALQ
options         KTR_COMPILE=3D(KTR_ALL)
options         KTR_ENTRIES=3D4096
options         KTR_MASK=3D(KTR_SUBSYS)

load linuxulator, set next (via root)

sysctl debug.ktr.alq_file=3D/root/ktr.out
sysctl debug.ktr.mask=3D32
sysctl debug.ktr.alq_enable=3D1

reproduce bug and _before_ unloading linux.ko do

sysctl debug.ktr.alq_enable=3D0
ktrdump -ctH -e /boot/kernel/kernel -i /root/ktr.out -o /root/ktr.log
