Fedora :: (EE) NOUVEAU(0): 1432: No Valid FB Address In PCI Config Space
Sep 15, 2009
I have a problem with 32Bit Fedora. I have it installed on my desktop pc, and it works, but in my laptop it doesn't. On my laptop, I have 64Bit, but wanted to reinstall and use 32Bit instead. Whenever I try to install 32Bit, the loading bar finishes, then the screen goes black, and enters the terminal, blinking rapidly, spamming mtrr 3 not used. I've tried a few things to fix this, but I haven't had any luck.
I have another similar problem with 32Bit on my desktop. It is working right now, but yesterday I installed a NVidia driver, and the mtrr 3 error occurred, forcing me to reinstall, without the NVidia driver.
EDIT: I tried
X -configure
Then i ran
X -config /boot/xorg.conf.new
The errors that show up are these:

When I install the FC11 by using"Install or upgrade an existing system"or"Install system with basic video driver"mode...Point 1, I can't config the network config ( IP Address ), due to theerror of network manager...Point 2, I can't enter into the text mode to do the installation steps.Remark:The machine is provide Web,DNS, and Mail Server on the NET ( Internet )
I would like to set my FireFox up so that when I type something in the address bar that is not a url, it will automatically do a google search. I have done this before, but that was a while ago and I can't remember what settings to change in about:config.Currently, when I type something that is not a url, it performs a search and then automatically opens the first web page that it finds, like a "I'm feeling lucky" search. I just want to see a google list.
We use procmail to reformat and filter email messages sent from many lead capture websites where the clients enter their reply email address manually.When we receive the message at our application we send a welcome email, and receive back the Undeliverable Email message where the clients entries are invalid, but I would like to be able to kill messages with undeliverable email addresses on our mail server before they are delivered to our application.I have found discussions on filtering masqueraded addresses, but since the IP of the sending system is not related to the entered client's email address, this does not appear to help. I would think that it should be able to query the email server to identify if the address is valid.
Im an academic (university networks and security lecturer) studying/teaching network and operating system security, and inspired by the work of Hovav Shacham set about testing ASLR on linux. Principley I did this by performing a brute force buffer overflow attack on Fedora 10 and Ubuntu 9. I did this by writting a little concurrent server daemon which accidently on purpose didnt do bounds checking.
I then wrote a client to send it a malicious string brute forcing guessed addresses which caused a return-to-libc to the function usleep with a parameter of 16m causing a delay of 16 seconds as laid out in [URL] Once I hit the delay I new I had found the function and could calculate delta_mmap allowing me to create a standard chained ret-to-libc attack. All of that works fine. However .... To complete my understanding I am trying establish where I can find the standard base address for ubuntu 9 (and other distros) for the following, taken from Shacham:-
Quote:
[code]....
/proc/uid/maps gives me some information but not the base address ldd also gives me the randomised starting address for sections in the user address space but neither gives me the base address. Intrestingly ... when a run ldd with aslr on for over (about) 100 times and checked the start point of libc I determined that the last 3 (least significant) hex digits were always 0's and the fist 4 (most significant) where between 0xB7D7 and 0xB7F9. To me this indicated that bits 22-31 were fixed and bits 12-21 were randomized with bits 11-0 fixed. Although even that doesnt define the boundaries observed correctly.
Note: I am replicating the attack to provide signatures to detect it using IDS, and for teaching purposes. I am NOT a hacker and if needed to could reply from my .ac.uk email address as verification.
I'm having making network/internet connection with my laptop. I have:Toshiba 1415 S173laptop NetGear WG511T pcmcia card using madwifiNetGear WPNT511 pcmcia card using windows driver via ndiswrapperSlackware 12.2In both cases the card is recognized, and I can get a list of access points with iwlist.I can set the card to connect to the desired access point. I can use dhclient to get an ip address from the remote dhcp server. This works, the card is assigned a valid ip address on the desired network.Once I do this, however, I cannot access any network resources, no Internet, and no other devices on the network can see, ping, or access my laptop. It does this with with both cards, using madwifi or the windows driver via ndiswrapper.
How do I decide what IP address to enter in my config file when assigning a static IP. All of the instructions I can find say something like "of course you should modify the file according to your own settings." Should I just use the gateway and IP that returns from "iwconfig" and "route -nee"?
I have millions of small chunks of new's and delete's in my program. Even though no memory leak is detected through valgrind or purify, memory grows. But the growth is degrading over the number of times of the execution of the tasks. Can i think that fragmentation plays a role in this?
Suppose a process creates multiple shared mem segments as part of it job.Now is it always possible that on restart, that process can reattach to those previously created shared mem segments to the same virtual address spaces (returned on first time creation) ? My intention is use pointers over shared memory.So on restart I want those pointers absolute value to remain valid.
I know that fork() copies the address space of the calling process. Say, however, i have a linked list allocated. Will the list be copied over to the child process's space? If so, i would have to free them in the child process as well as the parent process, correct? Or will the variables be copied but not be pointing to any valid address? Or would it just kind of not do anything?example:

I'm running an embedded Linux kernel, and I want to obtain a real memory address from user space. After goggeling a little, I found that the only way was to use mmap to access /dev/mem. But I never used mmap. I want to load a program in memory, in order to make it available from another processor, that has access to the DDR, but not to the flash memory where program is stored. Here is the code I use:
Code: // Open file and get its size FILE* program = fopen(argv[3],"rb"); fseek(program, 0, SEEK_END); long program_size = ftell(program); fseek(program, 0, SEEK_SET); // Prepare memory to copy it in void* program_address = malloc(program_size+1); FILE* memory_stream = fmemopen(program_real_address, program_size + 1, "wb"); [Code]....
As i undertsand - out of 1GB of the virtual Address space for Kernel from 3GB to 4GB of the process address space, Kernel image (code, data, bss, stack, heap) resides staring @0x0 address. Vmalloc area starts either at the end of Physical ram size or at 896M. This 896M cap is mandated to ensure that minimum of 128MB is reserved as vmalloc_reserve for vmalloc,kmap etc.
Is the understanding correct? Now trying to map Physical Zones into this 1GB address space
Initial 16MB is mapped to ZONE_DMA 16MB - 896MB is mapped to ZONE_NORMAL 896MB - 1024MB is mapped to ZONE_HIGHMEM
Does this mean that Kernel image is residing in ZONE_DMA area? Any call to vmalloc() in kernel code will return address beyond 896M? insmod of any LKM will internally invoke vmalloc() to obtain contiguous area - where will this code physically located along with rest of kernel code in ZONE_DMA or in ZONE_HIGHMEM?
this may be asking too much (especially from leigh123, 'cause i know you're working hard), but i've lost track of the current status of the great nvidia driver vs. nouveau driver debate, and what we can hope to see in f13 in about 20 days. could you provide or point us to a layman's summary of what graphics capabilities we can expect with a "default" configuration when we bring up f13?
in particular, can we expect nouveau to provide 3-d for f13 (or in the near future)? nvidia install guides, leigh123, but despite your best efforts, the procedures seem to be getting more involved as time goes on, not less (and not noticably more reliable, either). between graphics card drivers and flash plugins fighting firefox (not to mention adobe fighting videos and hulu) it's discouraging to actually lose capabilities that were once available when upgrades are made.
I have a machine running FC 13 and a GeForce 210 Graphics card. I'm running the 2.6.33.3-85 kernel (if I use the newer kernels like 2.6.34.7-61, and 2.6.34.7-56, the X server won't even start; that was the subject of a different thread which didn't get answered). After a few hours, the screen is displayed in a disorganized state: each quadrant is displayed in the wrong space, and the X server won't respond to mouse movements (this isn't a screensaver). This is different from a previous problem where the X server simply hangs after an hour of so when I use GUI programs (that was also the subject of a different thread which didn't get answered). I think I'm running the Noeveau video driver, but not sure.
During boot I get a message along the lines of "nouveau 0000:00:0d.0 misaligned reg 0x0060081D". I then get dumped into emergency mode. This has happened before on this box, then went away with one of the F-15 upgrades, and has now returned.
What's frustrating is that I tested F15 at both the Alpha and Beta stages and didn't have this issue with the install, only after updating.. And the KDE Live spin loads w/o major issue suggesting that it is a software issue. I've tried two earlier kernels to no avail and don't know what to try next.
The problem with X not starting up started after I upgraded kernel from 2.6.38.6-26.rc1.fc15.i686 which is what the FC15 came with. Before that I had X, without installing the nvidia.com driver (whatever came with the stock FC15-XFCE spin).I tried booting the old kernel and at first it worked but X again would not run. Now, after, above operations (reinstall of kernel-devel + kernel headers and all dependencies like glibc-common, glibcs-headers, dkms, gcc..) booting the old kernel does not work anymore: the framebuffer animation of the Fedora logo fillingup freezes at some point almost at the end; HD LED blinking hard. Maybe this means fsck is running and I need to give it more time..? I'll leave it booting when I go for lunch and see how it goes...
I was building and testing custom kernels and somehow I managed to get the display configuration messed up so that when the computer boots up gets to starting the nouveau driver it displays garbage on the display. The boot up continues and I can login from another computer using ssh.
How do I reset the display configuration (or fix this problem)?
I have added nomodeset to the kernel parameters and the vesa drivers do work but I want the hi-res nouveau back without having to re-install f-14.
I have been working with ssh for a long time without problems but suddenly, without any changes to the configuration, I am facing problems. When I try to login I get the following message and the connection is closed:

I just switched from Ubuntu to Fedora (because of Unity) and everything works just fine. my printer. It is Canon LBP6000. A had problem installing it in Ubuntu as well, but finally I did manage it with this tutorial. Problem is that this tutorial does not work in Fedora, since update-rc.d is not valid in Fedora. I am not really a linux geek, just a long time user of Ubuntu. I can follow any tutorial given, but I havent found one for this printer & Fedora. Canon site says that this printer is tested on Fedora 12 and 13 64bit but I doubt it anyway. I am running Fedora 15 beta 64bit with Gnome 3.
I was trying to install Fedora 13, on to my laptop. I have 30 GB of unallocated space in extended partition. When trying to install Fedora 13, I got stuck, as the installer says that there is no free space for installation.can convert the unallocated space into free space.
I just wanted to check, I'm using nouveau on Fedora 12 with the latest updates and each time I wake the machine from suspend, the fan on my XFX 8800GT goes to full speed and stays there. I've read some nouveau stuff and they say that nouveau doesn't control the fan speed, so I think the card is running in a safety mode after wake up where it runs the fan at full speed to be safe. The only suggestion I saw for fan speed and nouveau was to use nvclock to manually adjust the fan but that sounds dangerous to me. I think I'll just go to the closed rpmfusion driver then if this is the case.
I am running F12. With prior kernels - 2.6.31.9-174.fc12.i686 or before - I could simply rename the nouveau.ko driver to nouiveau.ko.bad. Then the kernel would load the nv driver instead, and everything worked great. FWIW: adding rdblacklist="nouveau" to the kernel params in grub.conf didn't seem to do anything.
On a recent update, a new kernel was added: 2.6.31.12-174.2.19.fc12.i686. I did the same rename trick as before, but this time the kernel still loaded the nouveau driver, and then X failed to load. So I had to fall back to the older kernel.
Is there a way to keep nouveau from loading with the newest kernel (ie, the one above)? And also, is there a way to keep nouveau from loading for any new kernels?
In the past I've played around with OpenGL development using the Mesa library. I have F13 installed now and would like to further explore OpenGL, but am trying out the default Nouveau/Gallium3d setup. As I understand Gallium3d is intended to replace Mesa3d so I'm at a loss as to what packages need installing to provide the header files and such needed to build OpenGL applications as a search for Gallium turns up nothing in the repos.
While it does mention nouveau, and I do use Nvidia graphics (PCIe GT 240) I believe the cause may be something else. Googling around leads me to a couple of forum threads that seem to relate to the core series of Intel processors, but I'm at a loss. I've also searched this forum however the search seems to either bring up every result under the sun and non seem to apply or no results at all. I know the card's supported as Ubuntu works flawlessly. I also tried booting in safe graphics mode, however the exact same thing happens.
I doubt using a USB stick in this manor would cause this problem, but if you suggest it i'll install from physical media.
I would post logs, however the shell it drops to seems to be severly limited (lacking reboot, even).
I have Fedora 15 installed in my PC and I use it both for gaming and work. Now the open source nouveau driver was working fine, until I had to install the nvidia driver so that I could play torcs, as I was unable to get good graphics in nouveau. Now, when using the nvidia driver, the gnome shell has become too slow and sometimes unworkable, though games run good. Is there any way so that I can use both the drivers and switch between them when needed (say use nvidia when gaming and nouveau while at work) without uninstalling and reinstalling them?
PS: when I boot up, the grub shows two options, one is the fedora with latest kernel and other is the old kernel. Is there a possible way that I use nouveau with old kernel and nvidia in the new kernel? This will really help in switching games and work.
