Another FreeBSD compatibility report

“It works…”

Keeping some notes here for future reference, in case a new setup is needed or people ask questions.


FreeBSD 12.0-CURRENT #0 r322167: Mon Aug  7 15:19:45 UTC 2017 amd64

Why not 11-STABLE? no particular reason. New hardware, I figured 12-current would have better driver support.

SKU 90MB0TE0-M0EAY0, Prime B350M-A (Asus)

  • Has own smart integrated power scaling so “powerd“ must be disabled:

    • the on-board power management chip doesn’t seem to be fully recognized (some errors show up);
    • integrated board just does work just fine so no need to run an additional program that takes CPU cycles.
  • PS/2 keyboard and mouse - fully functional:

    kbd1 at kbdmux0

    (no mouse plugged in so no device activated)

  • On-board Realtec gigabit Ethernet - fully functional:

The drives advertise 512-byte logical sectors, 4096-byte physical sectors however my own benchmarking shows that the unit of transfer that exposes best performance is 64KB, with 32KB delivering 90% of best.



Advertised as “Gigabyte,” is really an Intel dual channel chipset in disguise.

Needs this in /boot/loader.conf:


Fully functional:

iwm0: <Intel(R) Dual Band Wireless AC 8260> mem 0xfe100000-0xfe101fff irq 35 at device 0.0 on pci7
iwm0: hw rev 0x200, fw ver 22.361476.0, address xx:xx:xx:xx:xx:xx

Activate with /etc/rc.conf:

ifconfig_wlan0="WPA SYNCDHCP"

(and appropriate /etc/wpa_supplicant.conf)


Motherboard and processor do not provide integrated graphics, so had to go for cheap (!) external adapter.

SKU 11190-02-20G

Advertised as “Sapphire HD 6450 1GB DDR3.”

I do not use X11 on this computer so there was no need to look further, but I was curious.

This in xorg.conf does the trick:

Section "Device"
        Identifier  "Card0"
        Driver      "radeon"

Somehow the maximum resolution of my screen (3440x1440) triggers a bug in the chipset, so I had to force a lower resolution:

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes "2048x1080" "1920x1080" "1440x900" "1280x720"

Again no use for X11 so this is not a problem in practice.


Partition table needs some manual care, to ensure that the partitions are aligned on 32K boundaries (the unit for best performance I determined by benchmarking):

Unfortunately ZFS does not allow sector sizes above 8K. So I had to make-do with its default. Performance is adequate, if not optimal:

Suspend to sleep state C3 (acpiconf -s 3) works fine and resumes without problems. Including graphics and wifi.


In want of using this computer when I’m travelling but not leave it on all the time, it is important to be able to wake it up remotely.

Thankfully, wake-on-lan works fine with the on-board Realtek adapter.

Can wake both from suspended state (C3) and off (C5).
