Description Jim Wright 2002-01-30 07:49:45 UTC
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


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

Comment 2 Phil Knirsch 2002-03-26 11:02:29 UTC
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?


Read ya, Phil

Comment 3 Philip Pokorny 2002-05-07 16:23:24 UTC
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?

Comment 4 Phil Knirsch 2002-07-05 10:27:50 UTC
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.


Read ya, Phil

Comment 5 Philip Pokorny 2002-07-27 00:40:18 UTC
We've tested kernel 2.4.18-7.80 and it does have the support that was needed for
this motherboard.

Thanks!  Issue closed.

Comment 6 Phil Knirsch 2002-07-28 19:33:13 UTC
Thats nice to hear! Thanks for testing and reporting back.

Closing the bug then as fixed in RAWHIDE.

Read ya, Phil
