Subject: [lm-sensors] [Bug?] W83697: Broken readings for fan speed 10% of
Date: Sat, 31 May 2008 20:03:39 +0000	[thread overview]
Message-ID: <20080531220339.05dc83fd@neptune.home> (raw)

On a Commell LE-365 I get readings for fan speed that are broken about
10% of the time.
The board has a Winbond W83697 chip (I can't check the exact chip name
on the board as it's hidden by a heatsink, the photo from Commell, as
as well as the manual indicate a HG, the kenrel reports:
  [    3.572831] w83627hf: Found W83697HF chip at 0x290
  [    3.572831] WDT driver for the Winbond(TM) W83627HF/THF/HG Super I/O chip initialising.
  [    3.572831] w83627hf/thf/hg WDT: Watchdog already running. Resetting timeout to 60 sec
  [    3.572831] w83627hf/thf/hg WDT: initialized. timeout` sec (nowayout=0)
)

Below a sample (reformatted) output of
  while sleep 1; do
    date;
    cat /sys/class/hwmon/hwmon0/device/fan1_input;
  done

The 337k RPM and -1 RPM do not make any sense.
I can't tell if this is a regression as I just started monitoring
a few sensor values (with older kernels I just did a few manual
checks but never noticed broken fan speeds)

In case there is more data I can provide, please ask.
As the board is not in production use I can easily try out patches.

Regards,
Bruno
