I have found someone another report with the same hardware
https://lists.freebsd.org/pipermail/freebsd-questions/2017-December/280239.html
very interesting moment,
I do not have in my report all devices with class = dasp, include I2c controller, this from someone another report:
none0 at pci0:0:4:0: class=0x118000 card=0x07a81028 chip=0x19038086 rev=0x02 hdr=0x00
vendor = 'Intel Corporation'
device = 'Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Thermal
Subsystem'
class = dasp
none1 at pci0:0:20:2: class=0x118000 card=0x07a81028 chip=0x9d318086 rev=0x21 hdr=0x00
vendor = 'Intel Corporation'
device = 'Sunrise Point-LP Thermal subsystem'
class = dasp
none2 at pci0:0:21:0: class=0x118000 card=0x07a81028 chip=0x9d608086 rev=0x21 hdr=0x00
vendor = 'Intel Corporation'
device = 'Sunrise Point-LP Serial IO I2C Controller'
class = dasp
none3 at pci0:0:21:1: class=0x118000 card=0x07a81028 chip=0x9d618086 rev=0x21 hdr=0x00
vendor = 'Intel Corporation'
device = 'Sunrise Point-LP Serial IO I2C Controller'
class = dasp
all these devices do not present in my pciconf -vl output.
The question, how to fix this, I believe this is will be the first step in the right direction.
I have FreeBSD 12.0
