Hi,
I have a Asus CUV266-DLS, which uses the as99127f chipset. Everything
seems to work as it is supposed to, except for fan-speeds. They say 0.
Is that supposed behaviour since the as99127f doesn't have any
datasheets, or am I doing something wrong?
Best regards,
Stian

What kernel version are you using?

Does 2.4 work just fine for this chip and driver and 2.6 does not? If
2.4 also doesn't work, I would suggest bringing this up on the sensors
mailing list.

Doesn't work with 2.4 neither. I'll try the list, but I don't have much
hope for them doing anything. Quoting from the their webpage:
If you have problems, please lobby Asus to release a datasheet.
Unfortunately several others have without success.
Please do not send mail to us asking for better as99127f support.
Which I do ofcourse understand. I just wondered if there was some voodoo
I didnt' understand. Works fine with Motherboard Monitor 5 in Windows.
Thanks :)
Best regards,
Stian

Ah, then it isn't a 2.6 issue, so I'm happy :)
Good luck trying to get a spec sheet from them.

Have you tried adjusting the fan divisors (fan_div* in
/sys/bus/i2c/devices/*)? Keep multiplying the fan divisor by two, and
check the fan_input* devices-- you may have slow fans (or divide-by-two
speed sensors), and you might need a longer sampling interval to see the
lower speed.
Another option is to start the Windows monitoring program, perform a
warm reboot into Linux, and use i2cdump to see how they configured the
registers. Be sure to prevent your i2c drivers from loading, as a number
of them initialize the chips to default settings.

Wow, that worked! Thank you very much :) I would never have found this
out without you :) My fans are rather slow, so that might have been the
problem. Anyway, thank you :)
