RHBA-2010:0186 - Bug Fix Advisory

Topic

Updated lm_sensors packages that fix a bug and add various enhancements are
now available.

Description

The lm_sensors package includes a collection of modules for general SMBus
access and hardware monitoring.

These updated lm_sensors packages fix the following bug:

• running the "sensors-detect" utility while redirecting input from

/dev/null resulted in the following error message: "Use of uninitialized
value in pattern match.../usr/sbin/sensors-detect". This spurious error
message was caused by the referencing of an uninitialized variable, and has
been fixed in this update. (BZ#474383)

In addition, these updated packages provide the following enhancements:

Important: the kernel update for Red Hat Enterprise Linux 5.5 includes
updated hwmon kernel drivers that are necessary to enable newly-enabled
sensor types. The Red Hat Enterprise Linux 5.5 kernel should therefore be
installed along with this update.

• lm_sensors now contains support for the fschmd driver, which means that

the FSC Syleus chip is now supported. (BZ#513099)

• the following devices are now supported (BZ#473119, BZ#448223,

BZ#443742):

Analog Devices ADM1022, ADM1028 and ADM1029
Analog Devices ADT7470
Asus F71882FG and F71883FG
FSC Heimdal
Fintek F75373S/SG and F75375S/SP
Fujitsu Technology Solutions Heracles, Hermes, Poseidon and Scylla Intel
Core family thermal sensors
Maxim MAX6650 and MAX6651
National Semiconductor LM93 and PC87427
SMSC DMF1737
SMSC SCH3112, SCH3114 and SCH3116
SMSC SCH5027D-NW and SCH5127
Texas Instruments THMC50
VIA VT1211
Winbond W83L786 NR/NG/R/G
Winbond W83793 and R/G

Users of lm_sensors are advised to upgrade to these updated packages along
with the Red Hat Enterprise Linux 5.5 kernel update. Doing so resolves this
issue and add these enhancements.
