After loading the suggested driver and changing the hint.jedec_dimm.*.at="smbus0" to hint.jedec_dimm.*.at ="ichsmb0"
Everything is working smooth. Thanks! A reboot was not even needed!
ichsmb0@pci0:0:31:4: class=0x0c0500 card=0x79981462 chip=0xa1238086 rev=0x31 hdr=0x00
vendor = 'Intel Corporation'
device = '100 Series/C230 Series Chipset Family SMBus'
class = serial bus
subclass = SMBus
I'll submit some minor extra's to the man page if that’s OK.
Detailing a bit more how to find the correct location of the dimms and the correct driver to load (with pciconf).
Regards & thanks again!
Dries
