Here are my results with a Supermicro PDSMi MB (Intel E7230 (Mukilteo)
Smithfield chipset, ICH7R + PXH-V + Intel 82573V)
7.0-CURRENT #0: Thu Jul 27 12:28:34 EDT 2006.
The controller is detected:
ichsmb0: <Intel 82801GB (ICH7) SMBus controller> port 0x1100-0x111f irq
19 at device 31.3 on pci0
ichsmb0: [GIANT-LOCKED]
smbus0: <System Management Bus> on ichsmb0
smb0: <SMBus generic I/O> on smbus0
However communication does not seem to work:
# smbmsg -p
Probing for devices on /dev/smb0:
Device @0x30: rw
Device @0x32: rw
^C
ichsmb0: device timeout, status=0x41
ichsmb0: device timeout, status=0x41
ichsmb0: device timeout, status=0x41
I also tried running mbmon using SMB, however this is the result:
# mbmon -S
No SMBus HWM available!!
InitMBInfo: Unknown error: 0
Without any options, i get bogus temp values:
# mbmon
Temp.= 208.0, 0.0, 0.0; Rot.= 0, 0, 0
Vcore = 3.62, 3.62; Volt. = 3.62, 5.21, 11.80, 1.13, 2.09
