Red Hat Bugzilla – Bug 59061
lm_sensors does not yet support the Tyan S2462 dual Athlon board
Last modified: 2015-03-04 20:10:05 EST
Description of problem: kernel 2.4.9-21 included an update to lm_sensors, but not the most recent version. Version 2.6.2 of i2c and lm_sensors does work with the Tyan S2462 dual Athlon board. Please include this in the next release. And it would be greatly appreciated if this could also be in a 7.2 errata kernel in the near future. (User space tools are in lm_sensors package, but there is a new kernel driver which is required and only present in the newer releases, so I filed this against the kernel.) Additional info: I've been told by one of our engineers that the following change also needs to be made for this to work correctly: here's what you need to do in /etc/sensors.conf. under "chip "w83782d-*" "w83783s-*" "w83627hf-*" you'll find: # set up sensor types (thermistor is default) # 1 = PII/Celeron Diode; 2 = 3904 transistor; # 3435 = thermistor with Beta = 3435 # If temperature changes very little, try 1 or 2. # set sensor1 1 # set sensor2 2 # set sensor3 3435 add: set sensor1 2 set sensor2 2 set sensor3 2 then do: # sensors -s now the temperature should be reporting correctly.
The kernel support is fine, the config file might not be
Userspace has been updated as well, so i guess this should be fixed now. Can you try with the latest userspace version available via rawhide? Thanks, Read ya, Phil
What kernel has lm_sensors 2.6.3 included in it? The Tyan board also requires the following in /etc/modules.conf options w83781d init=0 force_subclients=0,0x2c,0x4a,0x4b In particular, the force_sublclients option did not appear until recent releases of the lm_sensors package (2.6.2?) or 2.6.3. Also, the SMBus interface in the AMD756 chipset may require a newer i2c version. What exactly would you like me to test? Perhaps a fresh install of 7.3 gold with the rawhide lm_sensors rpm?
Rawhide now contains the latest userspace lm_sensors package (2.6.3). The kernel will be updated shortly as well (kernel >= 2.4.18-5.61), after which the board should be detected corretly. If you could verify that this fixes your problem i'd greatly appreciate it. Thanks, Read ya, Phil
We've tested kernel 2.4.18-7.80 and it does have the support that was needed for this motherboard. Thanks! Issue closed.
Thats nice to hear! Thanks for testing and reporting back. Closing the bug then as fixed in RAWHIDE. Read ya, Phil
