Slackware :: Fans Working All The Time?

May 19, 2011

i'm using slackware 13.37. (Sony Vaio VGN-FS315H)

my fans are working all the time, they are loud and it's annoying.

I already did sensors-detect, but I get this message every time.

Sorry, no sensors were detected.

This is relatively common on laptops, where thermal management is handled by ACPI rather than the OS.

Ubuntu :: Banshee = Fans Running Hard?

Apr 28, 2011

I'm finally making the change away from rhythmbox for the now adopted Banshee and I'm noticing that my fans run really hard when I'm running banshee. I'm monitoring speeds and don't notice a huge increase in temp but the fans none the less run hard. CPU usage is running around 6% for banshee not nearly enough to cause this fairly large laptop so having the fans run hard make it a bit loud when around others

Hardware :: Bad To Plug Case Fans Into Motherboard?

Jul 8, 2010

I am going to upgrading the cooling in my computer, so I bought 3 case fans (the amount my case has room for). They have 4 pin connectors, so I was just going to plug 2 of them into the 2 available fan headers, and then plug the last one into a molex connector considering that they all come with molex adaptors. However, according to this site, your not supposed to because its too much strain on the motherboard? I am not (never have never will) overclocking so is that just for overclockers? My motherboard manual says it will work with 12 volt fans which are what these are.

General :: Maximum Number Of Partitions With EFI?

Jul 5, 2011

I was wondering what is the maximum number of partition on an GPT-partitionned drive under Linux. The GPT partition table can contain up to 128 partitions, but the device nodes for /dev/sda? (as described here, block device of major number 8) only allow /dev/sda1 up to /dev/sda15. Does that means that there cannot be more that 15 partitions on a drive, even on a GPT-partitionned drive?

General :: Maximum Date Value From A File?

May 10, 2011

I am facing a problem in finding out the maximum value of a field using awk .. The field is of date format i.e. (MM/DD/YYYY) ..

The contents of the file is :

2/2/2011 XYZ
2/2/2011 XYZ1
2/3/2011 ABC
2/4/2011 ABC


I need to find the maximum of the first column i.e. my output should be 2/12/2011 ..

I was using the below awk script : awk 'n < $0 {n=$0} {print n}{print $0}' <source_file having the above data>

But the output I am getting is 2/9/2011 instead of 2/12/2011 ...

what could be reason for this output and how can I get my desired result ..?

Software :: Sudden Shutdown/poweroff -- No, It's Not Bad Hardware Or Dirty Fans?

Nov 9, 2010

I just did a clean reinstall of Ubuntu (10.04 --> 10.10). After the install, any time I do CPU intensive work, my PC is suddenly shutting down like it's overheating.Everything was working fine for months, and started having problems immediately after the reinstall. so this is not a problem with my hardware, and it's not a problem with my fans needing cleaning -- it's a problem with software. So please don't tell me "that sounds like overheating, clean your fans". Something is different in software-land between 10.04 and 10.10 that is causing this to happen -- I assure you that the upgrade did not magically fill my fans with cat hair.

I have checked my log files, and can't find anything related to overheating -- searches for things related to lm_sensors, "temp", and "thermal" are not turning up anything in the system logs (syslog, kern.log, or messages). I also looked at the logs around the times of the sudden shutdown, and couldn't find anything unusual.How can I diagnose this? I'd like to file a bug report, but since I can't find anything in the logs, I honestly have no idea how to go about providing useful information.Is there anything besides overheating that might be causing my laptop to suddenly shut off?

General :: Maximum Number Of Files Per Folder?

Apr 28, 2011

I would like to ask you if there is any maximum allowed number of files per folder in linux (without risking it to lose everything). I am using openuse 11.4 with latest kde (4.6?).

I am trying something fast and dirty and it might be that one folder will contain like 10^6 files.

Is there is anything I should be warned about that?

Fedora Hardware :: Fans Wont Stop - Pwmconfig Returns Error ?

I am running Fedora11 on a brand new HP Pavilion Elite, and the fans just won't stop running at full speed.

I have tried


Which told me lm_sensors was already installed.

Next I did


Taking the default answer to all questions asked.



Gives me something like this:

Which I suppose are normal values, which do not require fans spinning at full power.

However,when I do

Ubuntu Installation :: 10.4 Upgrade, Xorg, Cpu, Fans Gone Nuts Running High/low?

Apr 28, 2010

I upgraded my Asus Eeepc 900a to 10.4 yesterday. Since then, Xorg has averaged between 30-40% CPU, and my fans have gone nuts running high/low/high/low, ad nausium.

Any ideas what might be going on? Another clue perhaps: on reboot or shutdown, I get a "program not responding" message with "unknown" as the hung program. I have not been able to determine what this program is or if it is related to the hyperactive Xorg.

General :: Boot - Maximum Vmalloc Parameter Size?

May 31, 2011

First off all, I'm booting from a large MEMDISK using PXE (900MB) . Due to our environment, I cannot decrease the size, nor move files to a nfs/iSCSI/... environment. Everything needs to be in that MEMDISK.

Now, when I try to run the OS, I get out of vmalloc space. How do I increase it to a number which allows such a large image to be mapped? I tried the parameter "vmalloc=1280M", but with that parameter, I don't get past the Booting the kernel screen.

Memory should not be an issue, since the machine(s) have at least 2GB RAM. (900MB MEMDISK + 256MB for other kernel stuff + 768MB for user stuff). The machine(s) have a Pentium 4 Extreme Edition processor, with hyperthreading and SSE2, but no EM64T.

How can I boot the system, and get past that message? Decreasing the MEMDISK size is not possible too. It is at the smallest we can get with our userland + kernel + modules.

General :: 512KB Maximum Transfer Size Per Command?

Apr 7, 2011

I'm using fc14 and the SG driver to test some SCSI (SAS) targets. In doing so, I'm bumping up against what appears to be a 512KB maximum transfer size per command. Transfers up to 4MB sometimes work, but often they result in ENOMEM or EINVAL returned from the write() function in the SG driver. I could not find any good documentation on how the SCSI system in Linux works so I've been studying the source for drivers in drivers/scsi.

I see that there is a scsi_device struct that contains a request_queue struct that contains a queue_limits struct that contains an element called max_sectors. The SG driver seems to use this to limit the size of the reserve buffer it is willing to create. I see that there are several constants used to initialize max_sectors to 1024 which would result in the 512KB limit I see (with targets having 512 byte sectors). At this point I have several questions:

1) When the open() function for the sg driver gets called, who initializes the scsi_device struct with the default values?

2) Can I merely change the limits struct to arbitrary values after initialization and cause the SG ioctls to set the reserve buffer to allow greater values?......

General :: Using / Usr / Bin / Time Always Returns 0 When Getting Maximum Resident Memory?

Mar 5, 2010

First time here at LQ, so if the post is in the wrong place, this is a bit programming related. I've been trying to find the maximum resident memory of a process in a memory constraint situation.

Instead of using top, or ps, which gives me real-time snapshot at the memory usage of a process, is there a way to determine the maximum resident memory used by a process? /usr/bin/time seem to provide this functionality within the format string


The minor page-fault is suspicious, does that mean memory is being used.. but not recorded? if so, how can I know how much memory is being mapped?

General :: Break Copy Process When Folder Size Reaches Its Maximum?

Mar 19, 2011

I have written a script.

a=`du -sh /root/samplefolder | cut -f1`
echo $a > testfile


The aim of this script is, when the folder reaches 20M then attributes will be set to that particular folder so that no newfiles and folders cannot be created or copied to that samplefolder. whenever i copy a file morethan 20M to that folder its getting copied fully and then the attributes were applied. But i dont want this to happen, when the folder reaches its maximum current write operation to that folder should be stopped automatically with a error.
