please, rebuild a kernel with next opts:

options         KTR
options         ALQ
options         KTR_ALQ
options         KTR_COMPILE=(KTR_ALL)
options         KTR_ENTRIES=4096
options         KTR_MASK=(KTR_SUBSYS)

load linuxulator, set next (via root)

sysctl debug.ktr.alq_file=/root/ktr.out
sysctl debug.ktr.mask=32
sysctl debug.ktr.alq_enable=1

reproduce bug and _before_ unloading linux.ko do

sysctl debug.ktr.alq_enable=0
ktrdump -ctH -e /boot/kernel/kernel -i /root/ktr.out -o /root/ktr.log

path to ktr.out should be direct.

please, send ktr.log to me
