Indeed, my kernel could find ichsmb. But mbmom still does not work. Are you
sure you have no other smb device in your board?
pciconf:
ichsmb0@pci0:1:1: class=0x0c0500 card=0x813f1043 chip=0x00e410de rev=0xa1
hdr=0x00
vendor = 'NVIDIA Corporation'
device = 'nForce PCI SMB Controller'
class = serial bus
subclass = SMBus
dmesg:
gaia::root ichsmb [518] grep -i smb /var/run/dmesg.boot
netsmb_dev: loaded
ichsmb0: <SMBus controller> port 0x5040-0x507f,0x5000-0x503f,0x5080-0x509f at
device 1.1 on pci0
gaia::root ichsmb [519]
Note that the kernel found ichsmb, but found no smbus.
Looking a bit deeper into the sources, ichsmb does attach to *ANY* PCI device
which identifies itself as a class "serial bus" and subclass "SMBus". It is a
mistake, and probably a bug. Maybe a leftover from debugging phase.
I am CCing: the ichsmb author to remember him.
