Hello,

Following an interesting discussion about temperature monitoring on
this mailing list, I decided to try this on a machine with the Gigabyte
K8-NF-9 motherboard (the only machine which I can get a /dev/smb0
device on).
It runs 6.1-stable:
root@kg-fil# uname -a
FreeBSD kg-fil.kg4.no 6.1-STABLE FreeBSD 6.1-STABLE #8: Sun May  7 22:51:56 CEST 2006     root@kg-fil.kg4.no:/usr/obj/usr/src/sys/FIL60  amd64

I load the following modules:
root@kg-fil# kldload ichsmb
root@kg-fil# kldload smb

which gives this output in /var/log/messages:
Jul 27 16:31:58 kg-fil kernel: ichsmb0: <SMBus controller> port 0xe800-0xe81f,0x
1c00-0x1c3f,0x1c40-0x1c7f irq 20 at device 1.1 on pci0
Jul 27 16:31:58 kg-fil kernel: ichsmb0: [GIANT-LOCKED]
Jul 27 16:31:58 kg-fil kernel: smbus0: <System Management Bus> on ichsmb0
Jul 27 16:32:16 kg-fil kernel: smb0: <SMBus generic I/O> on smbus0

But when I try 'smbmsg -p' I get this in /var/log/messages:
Jul 27 16:32:31 kg-fil kernel: ichsmb0: device timeout, status=0x00
Jul 27 16:33:02 kg-fil last message repeated 123 times
Jul 27 16:33:27 kg-fil last message repeated 100 times

Hmm, it doesn't look like it is working properly. I also tried loading smb first and ichsmb last, but nothing changes.
