Hi all,

I admit to = using beta software, and to the possibility that the issue is not in lm-sen= sors, but since I'm very interested in getting my issue fixed, I think this= list is the right place to start at least.

I upgraded = to Ubuntu 10.10 beta today, and the almost immediate result is that the fan= has become noisy as hell.

I have a De= ll XPS Studio 17 laptop, bought earlier this year. It has (among other thin= gs) an i7 Q820 processor.

I never ran= sensors before the upgrade (didn't have any fan issues there), so I don't = know if there's any actual differences in the output, but here goes.

Just runnin= g sensors give me:

acpitz-virt= ual-0

Adapter: Vi= rtual device

temp1: = +26.8=C2=B0C (crit =3D +127.0=C2=B0C)

temp2: = +61.0=C2=B0C (crit =3D +85.0=C2=B0C)

Since I've = little or no load on the CPU, I find the latter value unlikely high (but it= seems to be dropping now so I'll guess I will see how it evolves). Anyway,= I ran sensors-detect, and it found next to nothing apparently. I then down= loaded the svn version, ran it, and it came to a different conclusion (does= n't Ubuntu beta 10.10 have a recent lm-sensors?):

I could/sho= uld install the coretemp module, and so I did. Now sensors gives me:

acpitz-virt= ual-0

Adapter: Vi= rtual device

temp1: = +26.8=C2=B0C (crit =3D +127.0=C2=B0C)

temp2: = +57.0=C2=B0C (crit =3D +85.0=C2=B0C)

coretemp-is= a-0000

Adapter: IS= A adapter

Core 0: = +57.0=C2=B0C (high =3D +84.0=C2=B0C, crit =3D +100.0=C2=B0C)

coretemp-is= a-0001

Adapter: IS= A adapter

Core 1: = +57.0=C2=B0C (high =3D +84.0=C2=B0C, crit =3D +100.0=C2=B0C)

coretemp-is= a-0002

Adapter: IS= A adapter

Core 2: = +58.0=C2=B0C (high =3D +84.0=C2=B0C, crit =3D +100.0=C2=B0C)

coretemp-is= a-0003

Adapter: IS= A adapter

Core 3: = +57.0=C2=B0C (high =3D +84.0=C2=B0C, crit =3D +100.0=C2=B0C)

No fan spee= ds though, and I'd expected such info from a laptop this expensive. Looking= at sensors-detect again, I have this:

Probing for= Super-I/O at 0x4e/0x4f

Trying fami= ly `National Semiconductor'... Yes

Found unkno= wn chip with ID 0x8512

Is this som= ething of interest?

As a side n= ote, the fan turned itself down a notch now, but it is still more noisy tha= n I'd expect it (I think).

Anyway, if = anyone would like to help me with suggestions or similar as to what to look= for/what to test, it would be much appreciated. If there is something I ca= n do to help the lm-sensors project in this regard, I'll do my best.

Best regard= s,

Lars Ivar I= gesund
