overheating, spindowns

I'm working with a new install of Alpha 2 and generally finding my way through any minor issues.  However one major thing I noticed was that the computer (cpu) was running much hotter than with 9.04.  In fact the cpu temperature was in the 70's C consistently with the fan on high continually.  This did not occur with 9.04.  As suggested in some forum posts, I installed cpufrequtil and immediately the termperature abated, fan went back to more or completely normal functioning.  However the hard drive then started very frequent spin downs, clicking maybe a couple of times each minute.  I had had a similar problem way back on another computer with an older Ubuntu version.  There was a "dirty" fix for that which I just used for this problem (sudo hdparm -B 254 /dev/sda) which adjusts the Advanced Power Management pretty much eliminating spindowns - maybe not a good idea if traveling with the computer, but for now mine in stationary.

I feeling like I'm just patching things and maybe not getting to the heart of the issue.  As a separate point, but maybe related, it seems with Alpha2, some things such as terminal opening are more sluggish than with 9.04.  From the Statler forum, I'm not the only person to experience this overheating issue.   Any thoughts or suggestions on these issues? 

The computer I'm dealing with with Alpha2:
Winbook 12" notebook
512 MB Ram
1GB swap
Pentium M 1.60Ghz
80Gb HD

Old, but as I said, I never had this issue before with 9.04, XP, etc. on this computer.

Re: overheating, spindowns

I was dealing with a lot of fan noise and overheating on my Dell E6400. I seemed to have solved the majority of the problems by installing the following packages and their dependencies:

cpufrequtils
fancontrol
smartmontools
lm-sensors

For fancontrol, myconfig looks as follows:

$ cat /etc/fancontrol 
INTERVAL=10

DEVPATH=hwmon0=devices/platform/coretemp.0 hwmon2=devices/platform/w83627ehf.656
DEVNAME=hwmon0=coretemp hwmon2=w83627dhg

FCTEMPS=hwmon0/device/pwm1=hwmon0/device/temp1_input
FCFANS= hwmon0/device/pwm1=hwmon0/device/fan1_input
MINTEMP=hwmon0/device/pwm1=20
MAXTEMP=hwmon0/device/pwm1=55
MINSTART=hwmon0/device/pwm1=150
MINSTOP=hwmon0/device/pwm1=105

I also remember running sensors-detect (as root), but I don't recall which options I chose.

I hope that helps, but shout if you need any other configs. (Admittedly, this is a _bit_ of a drunk post, so I might have missed a few points. smile )

Re: overheating, spindowns

Thanks.  Except for cpufrequtils, these others only seem to be monitors.  I think I know what the issues are, at least some of them.  I've already installed cprfrequtils and it helped - although the cpu still seems hotter than it should. 

I'm not sure any of this answers why the system would be running significantly hotter with Alpha2 rather than 9.04.

Re: overheating, spindowns

It could be due to the newer kernel in Statler. A question though: does the laptop feel hotter or are you just looking at the numbers?

Re: overheating, spindowns

good question.  since it's not on my lap i've been going by the numbers (acpi temp in conky) and the fan behavior.  (would the fan have its own sensor)?  also, as noted above, cpufrequtils reduced both the number and fan action.  i'll try to get a feel for this as, although improved, it stills looks like it's running hot.

Re: overheating, spindowns

i'm now pretty sure that the computer is actually hotter.  why would the new kernel make the cpu run hotter for only some notebooks.  is there any other remedy other than going back to 9.04?

Re: overheating, spindowns

I've seen this problem before with Kernel updates, something was broken in the Ubuntu 7 release I believe, that caused this to happen. My suggestion, until a new kernel is released, is go with 9.04 #!. Most often it's a kernel update that needs to occur.

Re: overheating, spindowns

i'm willing to give the newer kernel route a try before going backwards, but frankly, i don't know what i'm getting myself into.  at the risk of sounding like an idiot, once i follow the instructions for installing liquorix, what's going to happen?  the new kernel will just seemlessly replace the older kernel and everything else will be the same or what?  thanks.

Re: overheating, spindowns

The new kernel will not replace the older one. iirc when booting (at GRUB2 screen) you will be able to choose which kernel you'd like to boot.

Re: overheating, spindowns

and will alpha2 maintain everything the way it currently is, configuration, settings, etc.?  updating and upgrading remain the same?

Re: overheating, spindowns

In leyman terms, the Kernel is a 'here is a device driver, here are some extensions to make all your hardware work'. It won't affect settings, it's merely a hardware interaction system at its core. Nothing should change, except your issue with your hardware. wink

Re: overheating, spindowns

Thanks so much.
Got the new kernel working.  The high temperatures and fan issue do still persist though and cpufrequtil is still useful for keeping things in check.

Re: overheating, spindowns

Sorry to hear it didn't help sad

I suppose you can consider getting a laptop cooler though.

Re: overheating, spindowns

i'm not much into the laptop cooler as a solution.

for what it's worth:
i reinstalled 9.04 and added what i wanted, reconfigured, etc.  sure enough, the computer is definitely running cooler.  the cpu temps with statler were high 60's to high 70's, even cracking 80.  with 9.04 it's running in the mid to high 50's, sometimes low 60's with no fan issues and not using cpufrequtil.   (cooler to the touch too.)  maybe it's my imagination, but it also seems faster.  go figure.

can anyone offer an explanation?  it's not the kernel or at least "upgrading" the kernel to liquorix .34 version didn't help.  judging from searching the forums, a few people seem to have experienced something similar, but it appears that it is not a wide spread or widely noticed problem.

Re: overheating, spindowns

Could be an issue with Debian itself, I remember that Ubuntu had this issue, Ubuntu managed to fix the issue somehow (I have no info on this, it's been a long time), but I'm not sure if Debian itself ever did? I thought it was a Kernel issue, but it obviously isn't. Though I do remember a lot of spin up and spin downs, and something to do with an error in the I/O of the filesystem when Ubuntu had this issue.

Re: overheating, spindowns

in my first post above i mentioned that i dealt with that older ubuntu issue which appeared to be related to some hd manufacturer parameters.  this issue seems to be something else as it was just a cpu temperature and related fan issue.  the current hd spindown issue only came after installing cpufrequtil which did help somewhat with the cpu/fan issue.

Re: overheating, spindowns

I just compiled the k10temp sensor and I'm shocked to see that my temp hovers (with very little cpu load) at 81 celsius... This laptop gets hot fast, but on 9.04 temps were around 65 celsius... Let's hope that cpufrequtil thing can help, otherwise I might have to move back to #!9.04

Re: overheating, spindowns

What laptop/processor are you using?  As above, I had this problem with an older Winbook with a Pentium M.  When I tested an even older Compaq Presario 2100 with a Celeron processor, the heat problem wasn't there.  Did  cpufrequtil help your situation?  Check to make sure your hard drive isn't going through abnormally frequent spindowns.

It would be nice to understand why this is happening on some hardware and not others.

Re: overheating, spindowns

with the liquorix kernel you could employ linux-phc to undevolt your cpu. this would lower temperatures and fan noise too
