I have a computer that freezes for about 41 seconds frequently. There's no logs other than a rtkit complaining about a starving bird. Then I started running vmstat, below is when the glitch happens. Any ideas on what could be causing the very high "in: The number of interrupts per second, including the clock." all of a sudden?

I've just update my computer to Ubuntu Lucid and I'm having some problems.After a random time, my mouse and keyboard stop working and I get the following lines on dmesg (I have to get this using a ssh connection):

II installed flashplayer by every different method I can so far, and all of them have the same problem. This problem presents itself, for example, while playing a video on ...... As the video loads, flashplayer is fine, but as soon as it starts playing, the browser tab begins to run at roughly 1 frame per 10 seconds. When I turn the browser priority to maximum in System Monitor, it improves slightly, going to about 1 frame per second. The strange part is, my CPU and memory usage barely spike at all, to less than 30%. This happens regardless of browser (have tried iceweisel and chrome). It happens with hardware acceleration on, and off. I have tried installing flashplayer from the tar.gz on the adobe website, from the repository (all three packages), and manually placing the plugin in the browser myself. The issue presents itself the same every time.
My system specs are: 1.83GHz duel core intel centrino processor, 3GB RAM, ATI Mobility Radeon HD 2600. Nothing fancy, but flash player performs as flawlessly as flashplayer can under windows (and also performed well in my previous Ubuntu 10.04LL install).

View 6 Replies View RelatedBasically I want to change the resolution on my computer as the desktop is partially lost off of the screen. The needed resolution is not available so I am attempting to add a new resolution. I have used the [URL] for information on how to do this. I am completely new to Ubuntu and entering code so a TON of the results online have meant jibberish to me as people leave out the basics which I cannot find. Here is what I've done so far in the terminal...
I enter:
xrandr
I get:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
HDMI-0 disconnected (normal left inverted right x axis y axis)

v: height 1180 start 1183 end 1193 total 1224 clock 59.9Hz
I enter:
xrandr --newmode <Mode''Line>
I get:
bash: syntax error near unexpected token 'newline'
Already I see an error message though without knowing what else to do I try to continue the code as follows...
I enter:
cvt 2020 1180
I get:
# 2024x1180 59.90 Hz (CVT) hsync: 73.31 kHz; pclk: 200.00 MHz
Modeline "2024x1180_60.00" 200.00 2024 2160 2376 2728 1180 1183 1193 1224 -hsync +vsync
At this point I see it shows 2024x1180 when I actually entered 2020x1180 which I find odd, though I try the next part with both 2024 and 2020 with same results.
I enter:
xrandr --newmode "2020x1180_60.00" 200.00 2024 2160 2376 2728 1180 1183 1193 1224 -hsync +vsync
I normally get no response after with a blank cursor, though one time I got:
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 150 (RANDR)
Minor opcode of failed request: 16 (RRCreateMode)
Serial number of failed request: 27

Sometimes after I enter my password after the screensaver has locked the screen, it will not take my password (even though entered correctly). It seems to lock up. After about 2 mins it says something about a time-out (wish I could do screencaps). Then it will reset and have a gray window the same size as the password input window but on the upper portion of the screen, and a password entry window as normal, but in the lower part of the screen. This time, it accepts the password and logs me in.This is a 2-part post.First, how to bypass having to wait for the timeout (for whatever is timing out).The second is to see if anyone knows an answer to the problem and a fix.After it freezes, hold CTRL-ALT and tap F1.This will taking you to a virtual terminal. Log in with your username and password. Then type:
Code:
$ pkill screensa
This will match gnome-screensaver and kill the program that is frozen. You then need to type

I got a problem with ubuntu and it is when I try to play games everything works alright but suddenly I get a random freeze, my entire screen freezes and I have to reboot in most cases, sometimes it turns to normal after a while. I had this problem in 9.10 and I got nvidia GTX 275. I dualboot with windows.
It could be my fans that are not working as the computer temperature gets up to 43 C or something when I game, however I've not seen how hot it is when it freezes.
Oh and I use 10.04, had the same bug in 9.10
I've been using 10.04 for a while now with no problems but for some reason it started freezing on the splash screen, 2 of my keyboards lights start blinking and thats it, I've tried with recovery mode and no luck either. The thing is I don't remember doing anything wrong.

I have had this happen only while using Firefox 3.6.8. This never happened with previous releases but they were using older versions of Firefox. That said I can't be 100% sure it's a FF issue but I think it is. I'll be online and suddenly the display will grey out, the CPU and will ramp up and I will loose control of the PC. Often it will return after a few seconds but not always. If control doesn't return I am usually screwed and can't even shut the system down. Initially I was thinking it was a Flash problem and both FF plugin Container and FF bin would be consuming vast ammounts of the CPU.
Now though I'm not so sure. I've tried deleting the FF profiles and starting again but this doesn't help either. A week ago I took the radical approach and completely deleted the partition and reinstalled a new version of 10.04.1 All was fine until a couple of days ago. But it started again. The screen greys out, everything freezes and I have no mouse/keyboard control. I tried to open terminal and no response. I try to shut down and my desktop icons dissapear, then the top/lower pane and I'm left with just the background and the cpu fan running full blast.
This last time I had terminal open with top running just in case. Problem stars again, greys out/freezes up etc and what I notice is Nautilus is using 99+% of the CPU. At the same time I loose my icons, panel toolbars etc. Now this is a fresh installation so what on earth's going on? It's happening on only one of my PC's The only other thing thats popped up is I've got an error message of "input/output error" a few times both in the Shell or again today struggling to get Terminal open or the pull down menu to restart the system. Hardware issue?
Ever since Linux kernels beyond 2.6.24.3, I've been unable to boot my HP Netserver LH3. It gives a kernel panic with a variety of messages that always include
"common_interrupt+0x38/0x39"
I tried everything from updating the BIOS and firmware, to myriads of differing kernel configurations (at 4 hours per compile, imagine the agony).
I also tried booting with every combination of the kernel boot parameters acpi=off, noapic, nolapic, irqpoll, etc., that I could imagine. No dice. In final desperation, I began unplugging PCI cards one by one before finally disconnecting the SDLT drive from the Netraid SCSI. It seems that in later kernels or versions of udev, sharing the SCSI bus with the LH3 drives causes conflicts. I have an additional AHA SCSI card in the machine, so will try connecting the SDLT to that and see how it goes.
I need cause an interrupt on a serial port. If I put a single HIGH on the RX pin, will that cause one? I all ready use the 4 control lines for data.Hope I am making sense?
View 5 Replies View RelatedIs there a way to interrupt the boot sequence, or execute it line by line? Alternatively, after a command has executed and the scree fills up, is there any way to "page up" on the screen?

I'm a bit of a Linux novice but have taken the plunge and got a old Dell machine set up with Fedora 13, it works fine for the most part. If I can get it to boot. Whenever I start it up the tri-color boot bars go across the screen but seem to freeze at various times. Sometimes right as its getting started, other times it will go all the way across but never actually do anything. I can sometimes get it to work if I get into GRUB and try a different kernel version. Is there anyway to pull up a more informative boot screen or some other way of figuring out whats causing the freeze instead of just watching the progress bar?

View 3 Replies View RelatedI am running Ubuntu karmic with Gnome desktop
I rebooted it as a package (GRASS GIS) wouldn't open properly, the splash screeen appeared but it appears to freeze and does not get to the login screen. I have tried to boot in safe mode but pressing ESC at grub doesn't work and Ctrl+Alt+F1 also fails to invoke anything. I can connect remotely via ssh. I have tried to remove Gnome desktop so I can just go straight to commandline but it still brings up the splash screen, I removed desktop using sudo apt-get remove gnome-desktop it said it did.
So why did this happen, last night I logged in via ssh and x-win server started a screen and did some work, the x-win server I lost my internet connection so putty aborted, this morning I couldn't connect to the screen so I did screen -wipe then rebooted as another package kept exiting.
any help much appreciated, this has happened at a vital time during my PhD and I need ubuntu back asap! In the meanwhile I am working via ssh with a slow Internet connection so not ideal!
Don't know if this is a coincidence, but the other day we had a power cut and my laptop went off. When I tried to reboot it got to the ubuntu start up screen, but when it tries to get to the "desk top" screen it all goes blue and black flashes. I have XP and Vista on the same machine and these both start up ok

View 2 Replies View RelatedI upgraded a week or so ago to 10.04, and everything was working fine. Then suddenly a few days ago the computer froze at the splash screen on startup. Thinking it was just some sort of neurotic, temporary issue, I restart again, but no luck -- same problem.
In terms of what I changed before the problem happened, I don't recall changing any system settings. On possibility is my changing things to skip the login screen and go strait to my account, but I believe I had done that a few shutdown/restarts before.
I just updated my netbook remix 9.10 to 10.04 and every time I boot up it freezes as soon as the login screen pops up. Before this said screen pops up I have the ability to move the cursor around freely, and if I mash the life out of enter I can get it to select my username, but freezes before the password entry bar has the chance to come up under it.
View 1 Replies View RelatedYesterday I upgraded from 9.10 to 10.04 (32 bit). Everything seemed to go well with no errors until the point where the system needed to restart at the end. After it restarted (and every power cycle since), it gets to the "ubuntu" screen with the moving cycle of square dots underneath, and stays there for ever. The screen resolution is absolutely goofed up, the word Ubuntu cannot be clearly read (looks like it is way overdriving the monitor). All letters seem to have like vertical bars on either side.
Below the Ubuntu and the dots, there appears to be two lines of completely illegible text (they just look like multicolored boxes about the size of characters.
I tried using the shift key to get to grub and try to boot into recovery mode--no luck. I tried using grub to boot to the previous kernel--no luck. It just sits there at the Ubuntu screen with this weird resolution/appearance.
I can boot from the Live CD and things work fine. I can see the file system, grub files etc. Any help debugging this would be most useful.
I downloaded the latest LTS last evening , placed it along side my Win 7 , things went well seemingly until I got the install done and restarted the pc. From the initial purple log in area, the second I curse to the place to put my pw the screen blinks off to the purple screen, devoid of the login section and freezes, taking my mouse control away and then it just sticks. I have restarted quite a few times with the same issue. Is there a known issue about Win7 and the latest LTS concerning the log in screen?
if so, what would I need to do to correct, do I need to jump backwards to an earlier version and wait for the issues to be corrected? Is that even possible?
I installed Ubuntu 10.10 on my laptop Lenovo T410 and I found a strange behaviour: sometime a part of the screen (small rectangle) freezes and there is no way to unfreeze it. The only way is to shutdown. I cannot use it to work Other colleagues of mine that installed the same Ubuntu version on the same laptop do not have any problem.

At first I thought it was just the mouse, but I noticed that the screen stops refreshing also. Hitting the space key (or any other key) brings the systme back to life (until it happens again).
It is a fresh install of Ubuntu 10.10, not much seems to be going on in the top list (compiz 1%, xorg 0.5%)
I am looking for ways to try and diagnose the problem (if not fix it )
