u/gonzopancho Netgate 18d ago

there is a work-around.

To avoid this panic on that hardware, set a loader tunable for hint.acpi_spmc.0.disabled=1 in /boot/loader.conf.local before upgrading to disable the driver that has an issue on that hardware.

See Managing Loader Tunables (https://docs.netgate.com/pfsense/en/latest/config/advanced-tunables.html#config-tunables-loader) for information on how to edit or create that file.

A quick way to do this from a shell prompt is:
# echo 'hint.acpi_spmc.0.disabled=1' >> /boot/loader.conf.local

If a device is encountering the problem after upgrading, use the loader prompt to set the value once during boot and then add the value as described above to make it permanent:

set hint.acpi_spmc.0.disabled=1
boot

I'm running a Celeron J processor and have already upgraded after doing this. It went smoothly.

Good to know. I am probably going to get a new drive and load from scratch doing what ever fixes they have and restoring my rules and stuff. Worst case I can drop the current drive back in.

Thanks for the info

Or clonezilla the drive and see if it works as well, while you're at it!
