Posted: Sat Apr 05, 2008 7:56 pm Post subject: higher temps on coretemp with 2.6.25* pls report (intel) |
|
|
Hi everybody,
I noticed much higher temps with 2.6.25* based kernels (currently rc8)
45 & 42 vs. 59 & 62 °C
(.24) (.25)
anyone noticed the same raise of temperature ?
I also noticed much louder noise due to faster-running cpu-fan/case-fans because of that high temperatures (3-4°C higher via cpu-cooler case-sensors)
cpu-model: Intel Core 2 Duo 6600
other core 2 duo users have reporrted to have encountered same issues
Intel-users please report !
thanks
p.s.:
if more are experiencing this, perhaps a report to lkml.org would be good, in order for a fix before 2.6.25-final release ? _________________ https://github.com/kernelOfTruth/ZFS-for-SystemRescueCD/tree/ZFS-for-SysRescCD-4.9.0

Are you on at least rc8? |

I think something might have gone into rc8-git3 or so. Check out git-sources. |

*bump*
unfortunately they are still happening with latest state from 2 days ago
anyone experiencing the same behavior - too high temperatures - ?
input is highly appreciated since 2.6.25 will go final soon & sadly I don't have time to test since when this happens (exams )
is there anyone who is willing to test-drive the releases between 2.6.24 & 2.6.25-rc8 / 2.6.25-rc8-git7 to find out since when this happens ? or any input
related to this problem ...
... I'm writing too much
thanks in advance _________________ https://github.com/kernelOfTruth/ZFS-for-SystemRescueCD/tree/ZFS-for-SysRescCD-4.9.0

Same here on Intel Core 2 Duo on 2.6.25-r9-zen0: temp under idle is 59°C
It might be the reading which isn't correct because my fan doesn't turn any harder?
I don't know if it's the same problem on 2.6.24-zen4 or zen5 because I can't seem to get those working (hard lock on udevd while booting) _________________ Windoze : Plug and Pay... |

in gentoo-sources .24 my E6600 is 25C at idle and 37C max under full load (compiling). I will try zen-sources and report my results! |

Hmm, I did zen-sources-9999 but it's still only showing 2.6.24 -- what am I missing? |

are you guys also experiencing a large number of wakeups when running two cores (as reported by powertop?) |

Okay, now I'm using gentoo-sources-2.6.25 and coretemp definitely does show much much higher temps than before. It is showing 47C but the CPU temp from uguru3 shows 29C (previously, uguru and coretemp would almost always match or be within 1 degree). |

it isn't (at least for me) - I've started experiencing this "behavior" since 2.6.25-rc* kernel-releases
2.6.24-zen* releases showed all the same behavior in terms of coretemp & sensors readout _________________ https://github.com/kernelOfTruth/ZFS-for-SystemRescueCD/tree/ZFS-for-SysRescCD-4.9.0

Thats because new kernel (lm_sensors, etc?, etc?)incorrectly thinks our cpu's Tj is 100C, whereas for all core 2 duo's it is 85C (100C is for C0 stepping and above, AFAIK). Substract 15 and you'll get real temps. |

Maybe because of this (hwmon/coretemp.c, 2.6.25):
Code: | static int __devinit adjust_tjmax(struct cpuinfo_x86 *c, u32 id, struct device *dev)
{
/* The 100C is default for both mobile and non mobile CPUs */
int tjmax = 100000;
....
if ((c->x86_model == 0xf) && (c->x86_mask < 4))
....
if (ismobile) {
err = rdmsr_safe_on_cpu(id, 0xee, &eax, &edx);
if (err) {
dev_warn(dev,
"Unable to access MSR 0xEE, for Tjmax, left"
" at default");
} else if (eax & 0x40000000) {
tjmax = 85000;
|
(hwmon/coretemp.c, 2.6.24):
Code: | if (((c->x86_model == 0xf) && (c->x86_mask > 3)) ||
(c->x86_model == 0xe)) {
err = rdmsr_safe_on_cpu(data->id, 0xee, &eax, &edx);
if (err) {
dev_warn(&pdev->dev,
"Unable to access MSR 0xEE, Tjmax left at %d "
"degrees C\n", data->tjmax/1000);
} else if (eax & 0x40000000) {
data->tjmax = 85000;
}
|
They set 85C for all cpu's with model 15 and stepping(not sure) <4. Core2duo E6600 has stepping 6...
In previous kernel all Core's with stepping >3 got 85C which obviously confused quad and 45nm owners, I think.
PS: Well, details are surely wrong, but the main idea is wrong cpu detection |

I've taken out the battery so that it wont contribute towards the temp. raising thingy.. any fix on this? _________________ whitesouls
