Red Hat Bugzilla – Bug 585203
Too high fan speed using nouveau driver - regression since F12
Last modified: 2010-05-02 10:11:28 EDT
Description of problem:
On my Dell XPS M1530 laptop with a nVidia 8600M GT graphic card, fan never slows down. I think it's the medium level of fanning, when F12 with nouveau or F13 and Win7 with nvidia use the lowest level. However my Core 2 Duo CPU is quite cool, i.e. less than 60°C. Even if it's 49°C, fan doesn't slow.
If I restart on Windows, the fan slows down within a minute.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2. Listen to fan speed.
Fan speed is too high.
Same fan speed as on F12.
F12 have no problem like this with nouveau, so it's a regression.
I think it can be a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=583956: when the reportee see high temperature, I see high use of graphic card without any reason, resulting in an high temperature which is not compensating by very high fan speed but medium fan speed.

Nouveau doesn't touch *anything* related to fanspeed control, and uses the exact same clocks/fan speeds as are initialised by the VBIOS, so I'm not entirely sure how you're seeing a difference in speed here.
Thank you for your response.
I'm seeing a difference in speed thanks to the fan noise. It's totally imprecise, I know. However I'm absolutely sure that fan speed is higher with F13 Nouveau than with F12 Nouveau (and F13 nVidia).
With F12 Nouveau or F13 nVidia : lowest level and sometimes a rush.
With F13 Nouveau : always medium level.
Maybe it's not Nouveau, or maybe Nouveau uses more the GPU than before.
I will give a new try to Nouveau today.
New try : same problem.
I made something like 5 reboots (with and without KMS).
/var/log/messages have 2 recursive lockings, so I join it. Bugs for these are https://bugzilla.redhat.com/show_bug.cgi?id=586488 (K99cpuspeed) and https://bugzilla.redhat.com/show_bug.cgi?id=572220 (Xorg).
I join other logs too.

last messages log with recursive lock
Really slow speed from my side, so I just send last /var/log/messages lock.
This report is the same as https://bugzilla.redhat.com/show_bug.cgi?id=529973.
However, the latter refers to Fedora 12 release. I will close this bug and update the version on the other one, you are welcome to post your issues there.
