Title: OPNsense 26.4.1-amd64 kernel boot but then stuck forever
Post by: clash on June 29, 2026, 09:40:12 AM
Hi,

I recently updated a firewall of one of my customers to OPNsense 26.4.1-amd64. After the reboot the System did not
come back. I took a look via IPMI and saw the kernel starts booting but stuck after 2 seconds.

I could successfully change to old kernel.

How many Kernels can I preserve, so that the the next update will not remove the actual working kernel.

Is this a known issue?

Can you provide more details on the machine OPNsense is running on, BIOS or UEFI, from what version did you upgrade and show the screen content from console menu to where it got stuck (either text or screenshot)?

If it works with an older kernel, maybe a device hint is needed to disable support for a device now.

Hi,

The machine is running via EFI und has a Intel(R) Xeon(R) E-2336. The motherboard is a
X12STL-IF (derived from dmidecode -t baseboard)

I will try to setup a downtime this weekend and make a screenshot via the impi console.

It's called IPMI :)

Do you happen to know how old the OPNsense installation is ?

Sometimes the Bootloader needs manual updating, but I am not sure if that's the case here...
