cpu constantly busy on debian sid without doing anything...
in [Debian]
|
From: Dietrich Bollmann on 18 Jun 2008 05:00 Since some time the two cpu's of my system (Debian sid running on a thinkpad laptop x60s) are constantly busy up to the point that even the key-repeat (pushing down some key for repetitious input) doesn't work anymore when using an external usb keyboard. the system monitor shows for example: CPU History: ... cpu1 76.2%, CPU2 77.8% and using top I find: Cpu(s): 70.3%us, 5.4%sy, 0.0%ni, 21.6%id, 0.0%wa, 0.0%hi, 2.7%si, 0.0%st but no busy processes are listed (Xorg: 4% cpu, gnome-system-monitor 3% cpu, hald 1%cpu, epiphany-browse 1%cpu, top 1%cpu, mysqld 0%cpu...) I wouldn't mind so much if I still could use crtr-h, ctrl-f, ctrl-n, ... normally in my emacs. But for the moment even editing a simple text file is a pain because of key-repeat being so slow :( Any idea what could be the reason?

Still the same problem after rebooting. Sometimes I had the impression that things are worse after rebooting and become better if I wait for a while. Than I thought 'beagle' might be the reason and deinstalled it - without any change. Today my computer runs for hours already and the little "System Monitor" applet in my gnome panel is at least half blue all the time (blue is used for showing activity). The system monitor shows peaks, not a constant activity pattern. If it was Windows I would think about some virus - but I am using linux... Could this be related to the new kernel? Thanks (will try to reboot once more now) Dietrich PS: I wrote about the same problem another email already - with the subject: repeated input by holding down a key doesn't work when using a USB keyboard Just in order to relate the two threads I include it here once again: > Hi, > > Since my last update of the debian sid system on my laptop > the repeated input of the same key by holding down the key > for a longer time doesn't work anymore when using an > external USB keyboard. > > I am using CTRL-b / CTRL-f / CTRL-p / CTRL-n etc. all the time > when editing texts - and find myself forced to hit the key an > infinite number of times like a professional gamer instead of > just pushing it once and holding it down for a longer time :( > > The laptop keyboard works as before... > > Any hint? > > Thanks, Dietrich > > - -- > Ron Johnson, Jr. > Jefferson LA USA > > "Kittens give Morbo gas.

I roll my own kernel, so I don't know which kernel you use. And you say that top(1) sorted by processor usage shows nothing? If your Stinkpad is directly connected to the Intarweb, it's *possible* that it's been infected by a worm. > Thanks (will try to reboot once more now) - -- Ron Johnson, Jr. Jefferson LA USA "Kittens give Morbo gas.

Trouble? Contact >listmaster(a)lists.debian.org I once saw a similar problem. I don't know if this is your case, but I will explain what I did. I checked everything from the hard drive with iostat to the memory, my cpu was being hammered much like yours but nothing seemed to fess up to doing it. I installed htop (http://htop.sourceforge.net/ also in the repos for apt-get goodness) and then I had it display Kernel threads (run htop at the command line and sort by cpu with F6 then Shift+K to show Kernel threads). In my case it was kacpid that was chewing up my cpu. So I edited grub to be acpi=off and it went away. That was sometime ago, but a quick Google search shows that it still happens to people on Debian and Ubuntu systems. I have no idea what causes it. Hope that helps! ~Stack~ -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmaster(a)lists.debian.org
