22.1 Legacy Series / Re: Kernel panic/crash every boot after a shutdown

The solution for B550 chipset and above system is to disable HDA audio in the BIOS to avoid the Kernel panic.

Thanks for this. I got the same advice on reddit. I'm assuming this is a bug FreeBSD needs to fix, and not opnsense?

22.1 Legacy Series / [SOLVED] Kernel panic/crash every boot after a shutdown

« on: July 09, 2022, 07:15:59 am »

Hi all,

I have a Lenovo ThinkCentre M75s Small Form Factor Gen 2 Desktop (https://www.lenovo.com/us/en/p/desktops/thinkcentre/m-series-sff/thinkcentre-m75s-gen-2/11tc1mdm75s). After installing opnsense 22.1.2, I'm noticing kernel panics/crashes that happen as follows:
- I boot the system
- Log in
- Choose the prompt to shutdown (5)
- Turn system back on
- Notice the system has hung as a kernel panic/crash and never auto-reboots. Keyboard is also unresponsive at this time.

Here is a picture taken via my phone of the last screen: https://imgur.com/a/0UGkRta. Reboots never cause this issue (option 6). Even after updating the OS, the issue still happens.

For the sake of testing purposes, I installed FreeBSD 13.1 on the same machine, and noticed that a similar weird issue happens. After I invoke "shutdown -p now", when I turn the system back on the OS boots up, then auto-reboots before showing me the login prompt; after this reboot I see the login prompt. This never happens if I invoke the reboot command. There are never any crash logs in the FreeBSD OS location /var/crash.

Any ideas? Let me know if you need more info, and how I can get it for you.

Thanks

21.1 Legacy Series / How to set custom DNS servers with and without Unbound?

« on: July 11, 2021, 05:07:46 pm »

Hi,

First of all, I'm really sorry if there is an answer for this somewhere. I've been googling this for an hour, and I am lost between what I think are contradictory answers, and not-so-obvious answers.

I just installed opnsense for the first time, and I want to use Cloudflare's 1.1.1.1/1.0.0.1 DNS servers. This is what I have done, and I'm not sure if this is right:
- Unbound is enabled by default, at Services->Unbound DNS->General
- In the above page, I enabled DNSSEC, register leases, and register static mappings
- I set the desired DNS servers at System->Settings->General->DNS Servers (both for ipv4 and ipv6, Cloudflare)
- I unchecked "Allow DNS server list to be overridden by DHCP/PPP on WAN" in the same page as above

My devices now show my opnsense local IP as their DNS server. I am assuming that Unbound is looking at the Cloudflare DNS settings I made earlier, and using those as its "dns root servers". Am I wrong? How does Unbound decide on which DNS servers to use, especially since I disabled "Allow DNS server list to be overridden by DHCP/PPP on WAN"?

If I am 100% wrong above with my desired outcome, what is the correct way to use Unbound, and also use any custom DNS? In the following post, franco states the term "dns root servers". I really want to understand the priority/how Unbound "knows" what the current root DNS servers are: https://forum.opnsense.org/index.php?topic=6332.msg26951#msg26951.
