Slackware :: Custom Kernel And Acpi / Thermal Settings - Fan Running Constantly

Jun 5, 2010

this isn't so much slackware specific as it is general linux related, but using the default huge slackware kernel included with 13.1, acpi reports cpu temps of about 55 celsius i always like to run my own kernels though, and using the latest stable kernel, i have compiled one using what i believe is necessary for my hardware, and everything works as expected except that acpi reports my cpu temp as 80 celsius at idle, causing my fan to be running constantly

so without simply using the generic config included with slack in the newer kernel, what do you think might be causing the thermal issues? i used diff on the two configs and the output is over 5,000 lines, so thats not a huge help, and im really not even sure what to be looking for the cpu is an intel i7 720qm, so if anyone might know any specific settings for that processor type needed for acpi to interface with it properly that would be much obliged here is my config for potential review: [URL] also, if i disable acpi entirely, the fan operates as normal but i cannot get readings obviously

Slackware :: Custom Built 2.6.37 Kernel And ACPI

Feb 12, 2011

I have a custom built 2.6.37 kernel where I have most of my devices compiled into the kernel. The only modules are related to nouveau (in case I want to go back to proprietary nvidia) and sound drivers. Everything seems to be running fine. However, in /proc/acpi, I'm missing a number of entries, such as thermal_zone/, dsdt, etc. I do have ac_adapter/, battery/, button/, event, processor/ and wakeup. I've gone through what I think is a very detailed review of my kernel config, and I can't find where I've missed something ACPI related. Here is my kernel config with the ACPI section.

# Power management and ACPI options
# CONFIG_PM_DEBUG is not set

Slackware :: During Boot After In Loads ACPI Thermal Zone?

Oct 11, 2010

It's only been a couple of days since I formatted my toshiba laptop's hard drive (i was running fedora without significant problems) and installed slackware 13.1 32bit. I did a network install because the dvd drive is not functioning properly. everything installed fine with the hugesmp kernel, but I started not being able to boot the laptop every single time I wanted to (especially after a reboot but also after a power up).

my observations:

-the pc might freeze in the very first toshiba logo screen (where you are prompted to press F2 to enter BIOS)

-or it might freeze when I get the lilo boot loader (not even the count down to choose kernel starts) - but i CAN use the arrows and press 'enter' to choose to load a kernel manually

-or just after it loads the kernel and the bios checks

-or during boot after in loads ACPI thermal zone

-or a little later during boot when the dhcpcd if broadcasting for a dhcp lease.

the first 3 are freezes, the last 2 are resets. especially if i need to reboot (or get the resets of the 2 last case), I will surely get stack in one of the first 3 cases afterwards! i have observed that rarely, after such a reset, if it actually gets stack in the toshiba logo, i might be able - pressing the poiwer buttonj repeatedly to actually overcome the 'freezing' there at which time i'll get to the lilo loader (the count down timer will not.. count down), but i can press 'enter' and I will finally get stack after loading the kernel and bios checks

So I have to powerdown the laptop and start all over again. Sometimes the whole boot process will proceed smoothly. and i'll get to a login prompt, and when I do I can keep the laptop up and running for virtually ever. that is it doesn't seem to be slackware related... Hwever the problems started after I installed slackware. I didn't have any problem with the fedora installation and i wonder if it has something to do with the network boot.... additional note, with feodra i didn't have a problem restarting or shutting down the laptop. now if i restart, the pc will go through the process of shutting down, but it will never actually reboot - i'll have to do it manually..

Ubuntu :: ACPI Thermal Zone Configuration

Aug 31, 2010

I originally installed Kubuntu 7.10 on an ACER laptop (exact model escapes me at the moment) and subsequently upgraded to 9.10 and then to 10.04. Starting with 9.10, I had problems with the computer suddenly turning off in the middle of doing work. Eventually, I figured out that when this happened, the bottom panel had gotten quite warm so it probably a thermal control measure. Further, I discovered that I could prevent this by setting the power regulator to powersave, which effectively kept frequency scaling at 50% and under which I never had the computer suddenly turn, the only exceptions being when unplugged the computer and replugged it in and it would switch to dynamic power policy thus running at full power.

However, after "upgrading" to 10.04, I can't do anything to restrict frequency scaling. Whether I set the regulator to powersave, ondemand or anything, CPU frequency can go to full capacity until it heats the CPU to the critical trip point, invoking poweroff. Sometimes, this would happen just a few minutes after "acpi -t" reported 40C (is there some way to test the output from acpi, I've seen it report obviously wrong figures such as 0C when the room was considerably above freezing?). While trying to figure out what to do, I discovered the /proc/acpi/thermal directory and subsequently the /sys/dev/... directory.

I would like to know which directory I should focus on and what files in order to establish trip points and direct actions that will force the system to reduce heating so it won't reach critical. It's not like it's particularly compute intensive tasks triggering this. I have had it happen while running nothing more than the windowing system, system monitor, terminal and paging through a file with less. I have looked for documentation online but have not found anything that clearly explains what I need to do. The only parts I understand from what I've found are "[critical]: S5", "[active]", and "[passive]". The "[passive]" line included items like "tc=..." and "device=0x...", but I have no idea whatsoever what any of those settings do and the documents do absolutely nothing to explain them.

1) what file I need to edit, 2) what options I can set in the file, 3) what values those options can take and 4) what effects those values have on ACPI's behavior. Lastly, the default setting HAVE GOT TO BE CHANGED. Having poweroff as the first line of defense against overheating is simply UNACCEPTABLE. What would happen if this occurs during the middle of a system upgrade? I know at least enough to figure what needs to be done, even if I can't figure out how to do it. Many users can't even do that and I don't think they should have to. The installation process should automatically detect what methods of reducing thermal output available (reducing frequency scaling, throttling, fans) and set trip points that invoke them before reaching critical.

Fedora Hardware :: Using Acpi: Thermal / Sysfs-api To Extend Battery Life

Dec 31, 2009

This link, acpi: thermal/sysfs-api, explains how the new thermal management sysfs class is built, but doesn't give much information about using it. Using watch, I can see that the cur_state of cooling_device2 changes from 0 to 5 when I check "Dim display when idle" in Power Management Preferences. But I haven't found an applet that changes cooling_device0 or cooling_device1.

Echoing different integers to the cur_state files limits the maximum cpu frequency for cpu0 and cpu1, respectively. This behaviour is expected from what I've read, and mimics the options in Windows power manager for extending battery life by throttling the CPUs. I've had no luck with google and local man pages, so has anybody has seen an applet for controlling /sys/class/thermal/cooling_device[0|1]/cur_state?

On a side note, a value of 1 does slow the CPU down, but it will still hit 100C (normal for an Intel mobile duo core). However, values of 2 and larger throttle enough to lower the maximum CPU temp. Since the CPU temp is a good indicator of power consumption, it's pretty obvious that these two cur_state files are intended to extend battery life. dd_wizard

Slackware :: No ACPI Support In Kernel

Jul 8, 2011

I use Slackware 13.37 32-bit version on ThinkPad X60s. I compiled two Window Maker dockable applications monitoring the processor temperature, fan speed, and battery status: wmpower (see: [URL]) and wmlenovo (see: [URL]). Both these applications refuse to work.

wmpower displays the messages:
CPU frequency scaling available
No power management subsystem detected
No power management support...
wmlenovo displays the message:
No ACPI support in kernel

Did I missed something obvious during the configuration of the system and ACPI doesn't work for me or there's some more serious problem with my system?

Slackware :: Custom Kernel, Now System Is Unbootable?

Jun 26, 2011

I compiled my own custom kernel for the first time. I tinkered with different options, nothing to difficult. I actually didn't expect it to work the first time.

I had kept the original lilo boot config just in case something was to go wrong. Now when I try to boot the system, I always get a "VFS: cannot mount root system on (8,3)". I googled this and found that my kernel did not support my root filesystem (btrfs). So I made an initrd with btrfs kernel module, but it didn't help. I then got a string of errors about how /dev could not be mounted.

My question is two-fold. First, how come when I configure the system back to when it was first installed, it still won't boot? Im using the same kernel ( Second, how can I get myself out of this rut without reinstalling?


append=" vt.default_utf8=0"
vga = normal
# Linux - Slackware
image = /boot/vmlinuz-huge-smp-
root = /dev/sda3
label = Linux

BTW, I have been maintenancing the system by chrooting into the device off of my slackware boot disk. Im on slack 13.37

Slackware :: Custom Kernel Not Boot After Current Lastest Update / Sort It?

Mar 2, 2010

After the bunch of updates with current, my custom kernel (2.6.33) can't boot.

The error is:
/sbin/e2fsck: No such file or directory while trying to open /dev/sda6

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate
e2fsck -b 8193 <device>

The /dev/sda6 is ext4 and is ok since it can boot with official huge smp kernel 2.6.33.

My custom kernel can boot before this bunch of updates in current.
What i missing in kernel?

Server :: Mounting Ext3 File System As Ext2 On Slackware With Custom Build Kernel?

May 16, 2010

I just rebuild the kernel for slackware 13, everything works, but root file system which is ext3 is mounted as ext2. Normally I've build ext3, ext4 and so on as modules, not in the kernel... but if I do this, then the kernel mounts the file system as ext2, which is build in the kernel. I also modified rc.modules so I can make sure that ext3,ext4,jbd are loaded, but it doesnt work.

Typically, I just have Firefox open, and that disk drive is sounding like it's writing the whole thing over and over.

I've opened the system monitor and looked for something obvious, but everything says, "sleeping". The computer seems to operate fine - no crashes, no odd behavior. What's this thing doing?

Ubuntu :: Kernel ACPI Bugs With Dell Optiplex 320

Dec 21, 2010

I'm trying to get WOL (Wake On Lan -suspend and hibernate don't work either) working in Ubuntu 10.10 amd64 on the above computer for a family member but seem to not be getting anywhere! WOL is enabled correctly I verified that after shutting down in windows XP that the computer came on with WOL. I have tried the following:

Enable wol
ethtool -s eth0 wol g

The computer shuts-down but won't wake up by WOL packet. Make sure the Ethernet (MAC0) can wake up PC
echo "MAC0" > /proc/acpi/wakeup
The computer shuts-down but won't wake up by WOL packet

Kernel parameters:
apm=power_off acpi=off

With all of the above, the computer doesn't not power down after shut down. The power button light is still on and has to be pressed to turn it off. Here is the strange thing: WOL works after manually tuning it off! I tried inserting apm module but it is not available.

General :: ACPI Error & Kernel Panic On Boot - Fedora 12

However, I reinstalled Fedora using a simple single drive setup (left the second drive without any partition), and the same error was returned. Is this an ACPI issue with this particular motherboard/BIOS? Any ideas for how I can fix this?

Slackware :: 13.37: Crazy Flashing Screen After ACPI Resume?

May 6, 2011

Slackware 13.37 is giving me ugly suspend/resume problems.When I suspend to RAM and my laptop wakes up again, I get a corrupt screen flashing like crazy.This happens when I suspend from the console and when in X11; be it by issuing 'echo mem >/sys/power/state' or 'pm-suspend'.Tried the 'save-pci' quirk for 'pm-suspend', no dice.Tried to POST the card with 'vbetool' after resume, no dice. Tried to save/restore vbestate before and after suspend/resume, no dice.What is one supposed to do to get this stuff to work in 2011?Funny thing that suspend-to-disk works as it should.Also, with 12.2 I would pick a VGA mode for the console in 'lilo.conf' and it would freaking stick. Not anymore. Now the 1st half of the boot is performed in my chosen mode (80x30), then it switches to maximum resolution with an idiotically unsightly small font.My laptop is an Acer Aspire 5101 with an ATI Radeon 200M card.Is anyone going thru the same hell or has anyone found a fix?

Slackware :: HD Constantly Spinning When On Battery Power

Dec 27, 2010

I'm running the latest slackware64-current on my Dell laptop (Inspiron 1420). I rarely run it on battery power, so I don't know when this behavior started, but now it seems when I'm on battery power the hard drive likes to spin down and then spin up. This is not after 5 minutes or so of inactivity. This is 30 seconds of inactivity because I'm reading a web page or something. There is a noticable delay in the response of the system as a whole when the drive is having to spin back up. I'm also using xfce-4.6.2 with the xfce power manager. I've checked the settings, and I don't see anything about spinning down the hard drives. I've also looked through some ACPI rules, but I'm coming up empty.
