Description Frank Wang 2007-08-02 04:00:06 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; zh-CN; rv:1.8.0.12) Gecko/20070718 Fedora/1.5.0.12-4.fc6 Firefox/1.5.0.12

Description of problem:
 The sensors-detect in lm_sensors-2.10.0-3.1 finds w83627ehf, but the module can't be loaded. 

 [root@amd64 ~]# sensors
 Can't access procfs/sysfs file
 Unable to find i2c bus information;
 For 2.6 kernels, make sure you have mounted sysfs and libsensors
 was compiled with sysfs support!
 For older kernels, make sure you have done 'modprobe i2c-proc'!
 
 [root@amd64 ~]# modprobe w83627ehf
 FATAL: Error inserting w83627ehf (/lib/modules/2.6.18-8.1.8.el5/kernel/drivers/hwmon/w83627ehf.ko): No such device
 
     sensors-detect also ask me to append following to /etc/modprobe.conf and I did and rebooted without luck.
 #----cut here----
 # I2C module options
 alias char-major-89 i2c-dev
 #----cut here----


Version-Release number of selected component (if applicable):
kernel-2.6.18-8.1.8.el5

How reproducible:
Always


Steps to Reproduce:
1.boot kernel 2.6.18-8.1.8.el5
2.modprbe w83627ehf

Actual Results:
FATAL: Error inserting w83627ehf (/lib/modules/2.6.18-8.1.8.el5/kernel/drivers/hwmon/w83627ehf.ko): No such device

Expected Results:
module load correctly and prompt nothing

Additional info:
    Latest kernel in FC6 works with this sensor.

Comment 1 Phil Knirsch 2008-04-16 10:42:04 EDT
If the kernel already can't load the module this is more likely to be a kernel
problem than a lm_sensors problem, so i'm reassigning the bug to kernel.

Read ya, Phil

driver refresh from upstream

Can someone possibly test this driver refresh patch on the affected hardware?

Depends on drivers/hwmon update - BZ 467994
Comment 7 RHEL Product and Program Management 2009-04-23 13:49:17 EDT
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.
Comment 11 Levente Farkas 2009-06-20 10:10:08 EDT
is there any chance that this will be in any 5.3 updates or only in 5.4. 
without this these sensors are not useable and there are many such motherboards:-(
Comment 12 Levente Farkas 2009-06-20 10:11:35 EDT
and as we can't access to 467994 we can't even manually patch these packages:-(
Comment 13 gijsbert.wiesenekker 2009-08-09 18:13:28 EDT
I posted a workaround for this issue on the Centos forums.
