Hi All,

I'm running X11 with screen saver and the i915kms graphics driver and
they seem to work, however I got the following messages when installing
drm-next-kmod from /usr/ports:

Installing drm-next-kmod-4.11.g20180224...
kldxref: error while reading
//boot/modules/i915_bxt_huc_ver01_07_1398_bin.ko: Bad address
kldxref: error while reading
//boot/modules/i915_kbl_huc_ver02_00_1810_bin.ko: Bad address
kldxref: error while reading
//boot/modules/i915_skl_huc_ver01_07_1398_bin.ko: Bad address

and I get them again when I install other kernel module (e.g. virtualbox

The machine in question is a Compulab Airtop, CPU (from boot in

CPU: Intel(R) Xeon(R) CPU E3-1285L v4 @ 3.40GHz (3392.22-MHz K8-class CPU)

Family=0x6  Model=0x47  Stepping=1

and from Xorg.log.0:

# uname -a
FreeBSD maxwell.mannynkapy.net 11.1-STABLE FreeBSD 11.1-STABLE #0
r330126: Thu Mar  1 11:27:24 PST 2018
tbr at maxwell:/usr/obj/usr/src/sys/MAXWELL  amd64

The machine has 32G of memory.  I checked out the latest 11.1 STABLE
kernel source, built a custom kernel from GENERIC by dropping the
network devices not present and the old ATA disk stuff, then checked out
the latest stable ports and did "make install" in

As I said, it seems to be running reasonably well, can anyone tell me if
I should worry about the error messages?

I have the entire "make install" output saved via the "script" command
if more details are needed.

Thanks in advance for any info or pointers.
