26.1, 26,4 Series / Re: DEC840 gets stuck on boot ...
Last post by feld - May 18, 2026, 10:58:54 PMoh this went very, very badly.
I set the sysctl in the webif as you suggested and instantly it killed the entire firewall. No traffic can go through, serial console spewing out debug data at max rate. I'm guessing 115200 is still a bottleneck, this clogs up the kernel from doing anything useful. Even if I wanted to SSH from one of the igb interfaces, it wouldn't work.
Not good.
Eventually manage to get a single user mode shell before those sysctls get applied on boot. I manually edit the config.xml to remove the sysctl entries. Reboot again.
Now I get a kernel panic every boot when it loads the driver. Removing the SFPs and leaving it powered off for a while doesn't help, every boot is a kernel panic.
Luckily I have a spare DEC 2700 I could install/restore my config onto and swap the hardware in place to get my network back online, but this DEC840 is pretty much a brick right now.
In the debugger after panic, I get this output:
Attempting a full reinstall on this DEC840 now.
edit: the reinstall was successful

General Discussion / youtube going offline
Last post by oriagranat9 - May 18, 2026, 10:40:10 PMHey folks,
I have an OPNsense router that has lately been causing me a lot of trouble. Whenever I'm browsing YouTube trying to watch videos, it takes a really long time to load and even pops up a "YouTube is offline" message.
I have diagnosed that the issue is coming from the network, as it happens to all devices (Wi-Fi and LAN). When using a cellular network on my phone or a hotspot, this doesn't happen.
My current setup is: ISP (FTTH) -> Router (SFP port - PPPoE) -> Main switch -> LAN + Wi-Fi.
I'm using Unbound on both Cloudflare and Google DNS, and Dnsmasq for DHCP. There are no VLAN definitions or anything configured to block traffic on the main LAN network.
I would really appreciate the help!

Aber wenn es eine Telekom-Leitung ist, geht es nicht, auch das schrieb ich schon.Alles klar, war mir nicht sicher, ob es da um die Leitung oder dann wirklich den Provider geht...
hast du ne Idee was es sonst sein kann?

Last post by feld - May 18, 2026, 09:21:24 PMQuoteInstead of directly fetching from the serial console you can also pipe "# dmesg" into a file, but make sure it has the ---<<BOOT>>--- in there.
I can't, because it doesn't finish booting to the point where I can get a shell and look at dmesg :)
Quote> Possibly unrelated, but is one of the ax ports configured for DHCP as a client?
that is correct, ax1 is a DHCP client to my ISP
