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

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
