I just bought a AliExpress N5105 router box with 4 x Intel 226v NICs. Seems to be an issue with some OS’s not being able to reboot properly. When you reboot, it just shuts off and you cant turn it back on unless you unplug the power cable and back in again. It has done it with Proxmox (per another source) and with Windows 11 Pro. It seems Windows doesn’t handle the C-State setup in the BIOS very well. I just disabled the C-State completely. This resolved it.
Press DEL -> Bios Go to Advanced -> Power & Performance Go to CPU – Power Mgmt Control Scroll down to C States -> change to disabled
Then I like for my device to stay on after a power loss, so go back to Advanced -> hardware monitor -> change power recovery to “stay on”.
Maybe Windows has an update for this or firmware update to fix this issue. I will be installing OpenBSD on this so doesnt matter for me.
NOTE:
I had no issues with Ubuntu 23.04 (latest) and OpenBSD 7.3 under the default BIOS settings with C States enabled. I looked for firmware updates in Windows and in Ubuntu, there were none.
Update:
OpenBSD doesn’t handle the c states well either. the ACPI process had the first cpu core pegged high with acpi0 interrupts. No adjustments I tried worked. I installed FreeBSD and its legit. No issues so far. This is probably due to the fact that PFsense backports all their drivers for these small router devices into FreeBSD upstream.
Update 7/25/2023:
So there is a BIOS update that will fix the OpenBSD ACPI issue. See my latest post.
