We are using Fedora Core 3, starting with kernel-2.6.10-1.766.FC3.src.rpm and applying these additional patches: linux-ipmi-2.6.10-base.diff linux-i2c-2.6.10-nonblock.diff linux-i2c-2.6.10-i801_nonblock.diff linux-ipmi-2.6.10-smb.diff patch-linux-2.6.11.5-bmcsensors.diff We are using lm_sensors-2.8.7-2.i386.rpm ipmitool-1.8.2-1.i386.rpm We have a patch in ipmitool which is just a fix to the rc script it includes to load the ipmi_smb module. You are probably more interested in the modules we load, and the order we load them in. I included the full list below, and marked what I think are the relevant ones (>>): [root at localhost ~]# lsmod Module Size Used by nfsd 185697 9 exportfs 9921 1 nfsd lockd 59625 2 nfsd >> bmcsensors 53861 0 >> i2c_ipmi 8397 0 >> i2c_dev 13249 0 >> ipmi_smb 18601 1 >> ipmi_devintf 11077 0 >> ipmi_msghandler 41509 3 i2c_ipmi,ipmi_smb,ipmi_devintf sunrpc 135077 19 nfsd,lockd md5 8001 1 ipv6 236897 20 ip_conntrack_ftp 76145 0 ip_conntrack_tftp 7921 0 iptable_nat 27493 1 ipt_state 5825 3 ip_conntrack 45317 4 ip_conntrack_ftp,ip_conntrack_tftp,iptable_nat,ipt_state iptable_filter 7489 1 ip_tables 20929 3 iptable_nat,ipt_state,iptable_filter video 19653 0 button 10577 0 battery 13253 0 ac 8773 0 uhci_hcd 33497 0 ehci_hcd 33737 0 hw_random 9429 0 >> i2c_i801 13053 0 >> i2c_core 29889 5 bmcsensors,i2c_ipmi,i2c_dev,ipmi_smb,i2c_i801 e1000 84373 0 floppy 56913 0 raid1 19393 2 dm_snapshot 20709 0 dm_zero 6465 0 dm_mirror 24861 2 ext3 117961 28 jbd 57177 1 ext3 dm_mod 57925 32 dm_snapshot,dm_zero,dm_mirror ata_piix 12485 4 libata 44101 1 ata_piix 3w_9xxx 35013 1 sd_mod 20545 8 scsi_mod 115649 3 libata,3w_9xxx,sd_mod [root at localhost ~]# Having done this, I can read the sensors via ipmitool, or via lm_sensors: [root at localhost ~]# sensors bmc-i2c-1-00 Adapter: IPMI adapter 1.8V: +1.81 V (min = +1.61 V, max = +1.96 V) 5.0V: +5.05 V (min = +4.55 V, max = +5.58 V) 12V: +12.45 V (min = +10.78 V, max = +13.20 V) BoardTemp: +29.0?C (high = +78?C, hyst = +2?C) CoreTemp: +39.0?C (high = +88?C, hyst = +2?C) IPMI-i2c-0-42 Adapter: SMBus I801 adapter at 0400 [root at localhost ~]# ot at localhost ~]# ipmitool sensor Baseboard 1.8V | 1.808 | Volts | ok | na | 1.613 | 1.665 | 1.912 | 1.964 | na Baseboard 5.0V | 5.055 | Volts | ok | na | 4.555 | 4.705 | 5.430 | 5.580 | na Baseboard 12V | 12.454 | Volts | ok | na | 10.780 | 11.152 | 12.826 | 13.198 | na Serverboard temp | 29.000 | degrees C | ok | na | 0.000 | 5.000 | 65.000 | 78.000 | na Proc1 Core temp | 39.000 | degrees C | ok | na | 5.000 | 10.000 | 81.000 | 88.000 | na Proc IERR | 0x0 | discrete | 0x0000| na | na | na | na | na | na P1 Thermal Trip | 0x0 | discrete | 0x0000| na | na | na | na | na | na Interrupt Button | 0x0 | discrete | 0x0000| na | na | na | na | na | na ID Button | 0x0 | discrete | 0x0000| na | na | na | na | na | na [root at localhost ~]# The bmc sensors patch was from <http://bmcsensors-26.sourceforge.net>, and the others were from <http://openipmi.sourceforge.net/> It took me quite a while to get this working too; I started by trying to talk to the sensor chips directly, but eventually I worked out that they are probably only visible through the mBMC chip. The mBMC chip sits on the visible i2c bus, and then has the actual sensor chip on a secondary i2c bus behind that, I believe. I did manage to read one of the fan speeds via a driver I wrote, but couldn't get at the sensor for the cpu fan speed, so didn't persue that. I don't think you'll have any joy with kernels newer than 2.6.12 because the bmcsensors code wont work. It is being rewritten, I believe, but I don't know the status. Richard
