In first sorry for my english.
I need to use Lotus Notes for Linux on FreeBSD. On 
http://www.notes.net/r5linuxforum.nsf/7d6a87824e2f09768525655b0050f2f2/0f3a1c7d48dc0b93852567de00530495?OpenDocument&Highlight=0,FreeBSD
I find full recipe how to do it, but it was for 3.2-stable.
I recompile kernel with all options from recipe and install Lotus on my
computer.
I found what if kernel compiled with options:
options               SHMALL=4097
options               SHMMAXPGS=4097
options               "SHMMAX=(SHMMAXPGS*PAGE_SIZE+1)"
options               SEMMAP=255
options               SEMMNI=235
options               SEMMNS=255
options               SEMMNU=235
options               SEMMSL=255
options               SEMOPM=201
options               SEMUME=201

if I using:
options         USER_LDT
then LN droop
after that I must using kill -9 command
if without -- LN said: error 0x19E.
if using options:
options         _KPOSIX_PRIORITY_SCHEDULING
options         _KPOSIX_VERSION=199309L
I take coredump, but not have message "error 0x19E"
After runs LN I take:
$sysctl -a | grep "kernel trap" | wc -l
835
The message is:
kernel trap 9 with interrupts disabled

How-To-Repeat: It repeats on 4.3-BETA and 4.3-RC every time
