<![CDATA[Kernel panic after OpenVPN? (SOLVED)]]>Hi,
I was wondering if someone else has experience the same issue? im running pfSense 2.2.6 on hyper V, so far everything was running smooth. I wanted to install OpenVPN which i have done in the past with no issue, but apparently when i try to connect it gives a kernel panic and pfSense reboots itself showing this error log? any ideas?

Thank you

In older versions deactivating ACPI was no problem and could be a workaround in such situations.

The "calcru: runtime went backwards" issue seems to be widespread on HyperV. Maybe you can find a solution when searching in the board.

So write /boot/loader.conf.local

You may also add it to loader.conf, but I'm not shure if it is overwritten at reboot or at updating pfSense.

so i added the config but then when pfsense reboot i get then this

panic: running without device atpic requires a local apic

had to revert to snapshot before

What bugs me is that i have this same setup in my test environment and works flawless.

as viragomann says adding

hint.acpi.0.disabled="1"

i see only in /boot/loader.conf and inside it I have

autoboot_delay="3"
vm.kmem_size="435544320"
vm.kmem_size_max="535544320"
comconsole_speed="115200"
hw.usb.no_pf="1"

Thank you

calcru: runtime went backwards from 7 usec to 3 usec for pid 0 (kernel)

Upgrading would be a good advice at any case.

Maybe it also helps to add the line

hint.acpi.0.disabled="1"

to /boot/loader.conf.local
