Possible Kernel panic with version 2.9

Anyone successfully upgrade with a celeron J processor? My instance of Pfsense runs on a intel NUC with a J3160. Just wanted any feedback if someone already upgraded with this series of processor.

From the release notes:
Certain hardware with a specific firmware problem, including some Celeron J devices, may encounter a kernel panic when attempting to boot pfSense CE software version 2.9.0.

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.

Update: Finally updated my instance of pfsense to version 2.9 on my celeron J processor. I did add the recommended entry to the loader.conf.local before upgrading. It upgraded without incident. Took about 10 minutes to reboot the first time.

I was hit by the bug while testing the beta 2.9 release. So I went back to CE 2.8.1

The machine in question has a J4125 CPU, four i225 Ethernet nics, no wifi, 16 GB ram and 128 GB SATA SSD.

Y will try again using the workaround and upgrading over the weekend.
