Description of problem:
"modprobe w83627ehf" produces an error
FATAL: Error inserting w83627ehf (/lib/modules/2.6.13-1.1524_FC4smp/kernel/drivers/hwmon/w83627ehf.ko): No such device
The device is not loaded. According to lm_sensors website (http://secure.netroedge.com) support for w83627ehf began in 2.6.13-rc1
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Type modprobe w83627ehf
Actual Results: Error message; device not loaded
Expected Results: Driver loaded
Mass update to all FC4 bugs:
An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel (18.104.22.168). As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.
Please retest with this update, and update this bug if necessary.
also, are you sure this is the right chip driver for your system ?
I tried the 2.6.13-1.1526_FC4smp kernel, but with the same result.
I am using a S'micro PDSMi board; I should have mentioned that before. According
to their website it uses the Winbond 83627EHF chip.
I notice that the winbond chip does not show up in the boot logs or the
/etc/sysconfig/hwconf file, but neither do similar devices on other boxes (for
example w83781d) which load fine on a modprobe.
I thought the w83627hf driver might be close enough, but alas no. It loads on
modprobe and runs lm_sensors but the output is nonsense.
It seems the S'micro web site information is wrong. Looking in the box its
apparently a W83627HF chip. This doesnt answer the question as to why the
voltages and temperatures are reported incorrectly, but its not a kernel bug.
Sorry to waste your time
