From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4 Description of problem: I'm using KDE on Fedora Core 4, with a 3Ghz IBM ThinkCentre tower computer and an NVidia GeForce 6800GT. I've got the nvidia drivers installed, and I typically run a few konsoles, firefox, thunderbird, KDevelop, emacs, and sometimes gaim. I've also got a Logitech mx500 mouse. After a few hours (not predictable exactly how many, but no longer than a day, b/c this usually happens after I leave the machine on overnight) the system is slow to where it's unusable. Scrolling in firefox with the scroll wheel is either slow or doesn't respond, and simple tasks in Thunderbird are slow or just don't respond. Clicking on quick launch icons in the task bar often freezes with a little box around the clicked icon, and sometimes the application launches after a minute, sometimes it doesn't. Starting any process takes forever, really -- I ran top, but had to wait a very long time for it to come up. Here is the output I got: top - 04:41:34 up 15:26, 5 users, load average: 1.17, 0.37, 0.18 Tasks: 112 total, 3 running, 109 sleeping, 0 stopped, 0 zombie Cpu(s): 0.2% us, 0.1% sy, 0.1% ni, 99.5% id, 0.1% wa, 0.0% hi, 0.0% si Mem: 1034028k total, 725644k used, 308384k free, 52488k buffers Swap: 0k total, 0k used, 0k free, 477132k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3473 root 16 0 278m 20m 4380 R 99.9 2.0 1:50.52 X 3569 tgamblin 16 0 33060 15m 12m R 99.9 1.5 0:02.10 kwin 3574 tgamblin 16 0 35252 17m 13m S 89.9 1.7 0:02.70 kicker 3572 tgamblin 16 0 35376 17m 13m S 49.9 1.7 0:03.37 kdesktop 3551 tgamblin 16 0 39108 15m 12m S 10.0 1.5 0:03.52 kded 2857 root 16 0 2744 652 564 S 5.0 0.1 0:00.46 nifd 3895 tgamblin 16 0 36908 17m 13m S 5.0 1.7 0:00.91 konsole 6666 tgamblin 16 0 5284 2444 1624 R 5.0 0.2 0:00.03 top 1 root 16 0 1748 572 492 S 0.0 0.1 0:01.00 init 2 root RT 0 0 0 0 S 0.0 0.0 0:00.00 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/0 4 root RT 0 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT 0 0 0 0 S 0.0 0.0 0:00.00 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/1 7 root RT 0 0 0 0 S 0.0 0.0 0:00.00 watchdog/1 8 root 10 -5 0 0 0 S 0.0 0.0 0:00.06 events/0 9 root 10 -5 0 0 0 S 0.0 0.0 0:00.00 events/1 10 root 10 -5 0 0 0 S 0.0 0.0 0:00.00 khelper 11 root 10 -5 0 0 0 S 0.0 0.0 0:00.00 kthread 14 root 20 -5 0 0 0 S 0.0 0.0 0:00.00 kacpid Or at least, that's the top of top. I've also seen this where thunderbird-bin was taking up 99.9 %CPU. I'm using the vmlinuz-2.6.11-1.1369_FC4smp kernel. This happens every time I use my computer, and I end up having to reset it manually. This usually involves the power switch, as ctrl-alt-delete is not responsive. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Turn on machine, startx 2. start 2 terminals, kde 3.4.1, kdevelop 3.2.1, firefox (latest), and thunderbird (latest). Maybe start a few instances of emacs and gaim, but not required. 3. wait. Actual Results: computer became unusable, unresponsive. CPU time of X, kicker, kdesktop, kicker, and kded shot up. Expected Results: computer remains operational for a very long time. Additional info:
could you please try to use nv driver from xorg-x11. Does this problem still appear. Thanks I have kde 3.4.1 running since 1 week without to have this problem!
Ok, I'm trying this with the NV Driver, and it seems good so far. I will update this if it does not freeze after a day. Does the nv driver support openGL? I cannot seem to get it to work. Also, it seems like I was using this driver with KDE when I first started with FC4, and the selection box created when you drag on the desktop was translucent. Now that I have switched back, it is not. What's wrong w/my configuration?
no, the driver does not support openGL. Please disable openGL feature in your KDE settings.
Hi all, I have a similar problem with the same machine, however I'm running it as a server, no X windows or whatsever. The problem is that the machine stops responding after approx. 6 hours of running. It seems like it is unable to read/write from/to the disks, load is 1.07 or more at the time. what is really strange is, that the machine has been running for 2 days (I did not lose my ssh connection to it) but uptime shows only 15 hours. I thought it had something to do with ACPI/APM, SATA driver or MD. so I played around, installed the 2.6.13 kernel and tired to disable acpi, raid... upgraded the machine bios to the latest of course... but the usage/not usage of apm/acpi, raid or plain disks (ext3) does not seem to affect the machine in any way. I disabled all powersaving in bios too. the result is still the same. after 5-6 hours the machine stops responding when trying to access disks. but there is absolutely no error/warning/whatever in dmesg. any ideas?
Peter, it's not the same problem and seems a kernel problem to me. You should fill this bug to the component kernel please. Thanks
