Hi, I'm trying to use lm_sensors on my system, and after running sensors-detect, I've run into a couple of problems: 1) The kernel module "smbus-arp" is needed but not available. 2) According to a diagnostic printed by sensors-detect, "[there is] no driver for Nat. Semi. PC87372 Super IO Fan Sensors yet, ask us for one!" Can anybody tell me how to acquire the "smbus-arp" module? I'm running the latest 2.6.5 kernel offered by YOU (namely, "2.6.5-7.104-smp") on a SuSE 9.1 Professional distribution. I installed the sensors RPM sensors-2.8.6-0.2. Likewise, exactly whom should I "ask" for the PC87372 Fan Sensor driver? I have enabled lm_sensors via the YaST-based run-level editor, but as it stands, I get only this information from sensors: % sensors eeprom-i2c-0-52 Adapter: SMBus I801 adapter at c800 Memory type: DDR SDRAM DIMM Memory size (MB): 512 eeprom-i2c-0-50 Adapter: SMBus I801 adapter at c800 Memory type: DDR SDRAM DIMM Memory size (MB): 512 Thanks in advance for any help.

needed by what? Did you read /usr/share/doc/packages/sensors/chips/smbus-arp ?

The lmsensors project? http://www2.lm-sensors.nu/~lm78/

By the user-level lm_sensors code, I presume. It's included in the list of four modules configured in /etc/sysconfig/lm_sensors by "sensors-detect." The ".../doc/..." file you mention doesn't tell me how to make this module available so it can be accessed when mentioned in the "modprobe" command produced by the presence of "MODULE_4=smbus-arp" in the lm_sensors configuration file. It also states "This is a demonstration driver...", which made me think it might not be fully functional. "Locate smbus-arp" lists only that documentation file. "Locate smbus", however, discloses a directory ("/sys/bus/pci/drivers/i801 smbus/") and two files within that directory ("0000:00:1f." and "new_id"). On the other hand, "locate" finds module object files ("*.ko") in the kernel director for all the other four modules mentioned in the lm_sensors configuration file ("i2c-i801", "i2c-isa", "lm85" and "eeprom"). The documentation file does say that "smbus-arp" should be loaded before any chip modules "so that it has an opportunity to assign addresses." Perhaps making the smbus-arp entry MODULE_1 instead of MODULE_4? Do I gather correctly that the name "smbus-arp" is chosen because this module's function is somewhat akin to ARP, the Address Resolution Protocol, which is used to find MAC addresses that correspond to particular IP addresses?

Yes, I finally tracked that down. It's mentioned on their "New Drivers" (http://secure.netroedge.com/~lm78/newdrivers.html) page along with a rather noncommittal statement that someone may be writing one soon. Randall Schulz

That doc states that the module is essentially useless except for testing purposes, so I wouldn't bother with it if I were you

OK, but then why does "sensors-detect" attempt to configure it? Further hunting on the net suggests that smbus-arp has been dropped from the 2.6 kernel since some time last year. So I guess the only real problem I have is that there is as yet no driver for the hardware monitoring chip (National PC87372, http://www.national.com/pf/PC/PC87372.html) on this motherboard.
