Kernel Panic when Upgrading to 2.8.0 beta

stephenw10

You can do it by simply running the single command:
echo 'hint.iwm.0.disabled="1"' >> /boot/loader.conf.local

Like:

[2.8.0-RELEASE][admin@cedev-7.stevew.lan]/root: echo 'hint.iwm.0.disabled="1"' >> /boot/loader.conf.local
[2.8.0-RELEASE][admin@cedev-7.stevew.lan]/root: cat /boot/loader.conf.local
hint.iwm.0.disabled="1"

That will also append the line to the file if it already exists.

At the console db> prompt ?

Nope at the pfSense CLI (or via the gui command prompt page). So you have to manually boot to 2.8 once or run it from 2.7.2 before upgrade.

Ah, ok, right. Of course.
But : what if his 2.8.0 doesn't boot /didn't boot (because of the kernel boot failure ) ?

Then you need to manually set that disabled at the loader prompt one time to boot into 2.8 first. Then run that command to allow it to boot normally after that.

I just want to verify your steps because I'm facing the same Wi-Fi problem.

First time I rebooted I didn't press the '3' key quickly enough to 'Escape to loader prompt' and so I got the damn error.
I rebooted (power cycle the NUC pfSense runs on - probably a better way than that) and then pressed '3', entered the loader and typed in

set hint.iwm.0.disabled="1"

followed by:

boot

and it completed the update and pfSense worked ok - until I rebooted. I then followed the same steps above to get it to boot and once it was running again, I opened the Web GUI and navigated to
Diagnostics > Edit File
entered the following path

/boot/loader.conf.local

and the requisite data

hint.iwm.0.disabled="1"

before hitting 'save'.

pfSense has booted fine since then for me.

It sounds like some people may have an existing file `"/boot/loader.conf.local" but that was not the caese for my install (or at least that's what it looked like when I loaded the file). YMMV.

Hmm, interesting if it's really disabled in the BIOS pfSense shouldn't see it at all. Something not working right there.

Correct. Under the list of devices in the BIOS on the NUC, WiFi is not checked.

Do you have any info if this has been fixed in 2.8.1?

@tomasz.kozlowski just updated to ver 2.8.1 with no problems.

The driver firmware loading issue is not fixed in 2.8.1. It's still broken upstream AFAIK. You will still need to apply one of the workarounds.
