Netgate Device ID changing on power loss

stephenw10

Ok it's almost certainly this:

ue0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=0
        capabilities=0
        ether 9a:95:62:30:fa:d5
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        drivername: ue0

I'd bet that MAC changes between boots. Check the boot log for errors about the MAC there.

Do you know what that is?

If you don't need it you can probably disable it with a loader hint.

@stephenw10 So from what I can gather, this Asrockrack board can share the ix0 port (which happens to be my wan) in addition to the dedicated IPMI port.

Posting the thread that I found this info on in case someone else has this issue in the future:

https://www.reddit.com/r/homelab/comments/ph9wgx/help_with_restricting_asrock_rack_x570d4u2l2t/

Running the following disables that sharing (which also happened to remove the ipmi from broadcasting on my WAN yikes)

 ipmitool raw 0x32 0x71 0x00 0x01 0x00

As for that ue0 interface:

ue0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=0
        capabilities=0
        ether 42:29:ea:ff:8a:1a
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        drivername: ue0

I don't know what that interface is, so it must be this "virtual" ipmi interface thingy, but it 100% changed after the hard power reset.

Can you let me know what the loader hint would be to just entirely disable it?

After running that IPMI tool cmd, here's the latest

Run at the command line: echo 'hint.ue.0.disabled="1"' >> /boot/loader.conf.local

That should prevent the device attaching.

You may be able to disable it in the BIOS which would probably be a better solution as it would survive a reinstall. And would not affect any USB devices added in the future.

n1ck31

@stephenw10 Thanks for that, unfortunately the NDI still changed again after a hard reset. (I double checked, its gone in the ifconfig command now)

Although that interface was probably part of the problem, it wasn't the only problem.

Do you have any other ideas? For now I've downgraded back to CE until I can get this solved.

Never mind, after another reboot, it's back. (ue0)

I've checked BIOS, nowhere to disable this that I can see.

provels

Are you bridging interfaces? If not, never mind.

stephenw10

Hmm, it didn't disable it?

Do you see the line as expected in /boot/loader.conf.local?

Try running: usbconfig dump_device_desc

That might show you what that device actually is.

n1ck31

@provels Not intentionally, asrock has no options for it other than this network bond config which isn't the same thing.

@stephenw10 Yep, I can see it there in the file, and nope it didn't disable it.

This is the output of that command:

I don't see it there... (yet its still in the system)

Yup so it's a virtual device. If there's nothing in the BIOS then maybe something in the IPMI setup?

How does it appear in the boot log when it attaches? You might need to try disabling cdce0 instead. If that's how it appears.

@stephenw10 Nothing in both places. Only things I can disable are the virtual media devices & KBM emulation. No mention of any virtual network adapters at all.

This is all thats mentioned of it in the boot log:

uhub2: 6 ports with 6 removable, self powered
uhub1: 6 ports with 6 removable, self powered
uhub0: 22 ports with 22 removable, self powered
Root mount waiting for: usbus0
ugen0.2: <American Megatrends Inc. Virtual Hub> at usbus0
uhub3 on uhub0
uhub3: <7-port Hub> on usbus0
uhub3: 5 ports with 5 removable, self powered
Root mount waiting for: usbus0
ugen0.3: <American Megatrends Inc. Virtual Ethernet> at usbus0
Root mount waiting for: usbus0
ugen0.4: <American Megatrends Inc. Virtual Keyboard and Mouse> at usbus0
ukbd0 on uhub3

@n1ck31 Maybe try disabling the BMC with a jumper and see if this helps.

stephenw10

It must list the device and the driver attaching to it in the boot log. Something like:

ugen0.3: <Realtek USB 10/100/1G/2.5G LAN> at usbus0
cdce0 on uhub0
cdce0: <CDC Communications Control> on usbus0
ue0: <USB Ethernet> on cdce0
ue0: Ethernet address: 00:e0:81:21:78:ea

And if it does appear like that try adding to loader.conf.local: hint.cdce.0.disabled="1"

Although that probably will solve the issue, that negates the scalped price I paid for this board originally - if i were to go this route I'd just buy a regular consumer board and swap it out.

Here's the full log file

It seems that it's usbus0 on xhci0, so maybe disabling xhci0?

You should disable the on-board audio, though I doubt it's connected to this issue:

pcm1: <ATI R6xx (HDMI)> at nid 5 on hdaa0
pcm2: <ATI R6xx (HDMI)> at nid 7 on hdaa0
pcm3: <ATI R6xx (HDMI)> at nid 9 on hdaa0

Ok the actual driver attachment looks to have happened after the bootlog completes but it should be in the main system log.

Yes, you could disable the usbus or root device completely but it would be better to disable just the Ethernet device if you can.

stephenw10

Try running: usbconfig -d ugen0.3 dump_all_config_desc

It looks like it has more than one config index, in which case we can force the other one which may make it fail to load.

I'll look into disabling the audio, agreed, makes no sense having that on.

Hmm, both indexs include CDC data which will likely be the ue0 device. The logs just after boot should confirm that showing cdce though.

It feels like it should be possible to add a USB quirk to just stop that loading but I don't see an option for that:

Otherwise disabling cdce0 or the USB bus or controller should be possible.

I have an older ASRock Rack motherboard, and I also had my share of struggles with their BMC port sharing. On this motherboard, from what I found in my research, this virtual AMD port appears when instead of using a dedicated BMC port, you share this port for other purposes, or when you only have one cable connected to a certain port.

As far as I understand and remember, the settings for this behavior are not in the BIOS but in the BMC’s web interface. In the Configuration section, there should be several options for network, link configuration, and choosing between shared or dedicated. One of these options should disable this virtual interface, but I’m not entirely sure. The motherboard manual might provide more detailed descriptions of the BMC settings, but on my board, these settings are quite confusing, and the manual doesn’t cover all of them.

Overall, I had a similar idea—to have access to both the BIOS and everything else. But as usual, since their BMC relies on Java, which can’t be updated, it’s impossible to use their applets because the board is no longer supported. In the end, I connected a PiKVM to this board.

For anyone considering purchasing an ASRock Rack, I highly advise against it if you plan to use the board longer than its support period (typically 2-3 years), as the BMC might "turn into a pumpkin" after that.
