Fatal trap 12 booting FreeBSD-CURRENT via isboot kernel module.

[Maurizio Vairani]

I am running
# uname
-a

FreeBSD  12.0-CURRENT FreeBSD 12.0-CURRENT #0 r328383: Thu Jan 25 04:48:52

After compiling the kernel module as discussed in this thread :
https://lists.freebsd.org/pipermail/freebsd-current/2018-January/068272.html

I can boot FreeBSD via iSCSI using iPXE. But when the isboot, the iSCSI
boot driver version 0.2.13, starts I receive a panic:

Any idea?
