Fedora :: Get The Message "IOMMU: Mapping Reserved Region Failed" 8 Times
Aug 4, 2011
System: F15-64bit, Intel Core i7 on Asus P6T mobo. I've upgraded to 2.6.40, and I'm regretting it!While 2.6.38 still works fine (apart from the usual random panics), 2.6.40 gives errors on boot, and reliably panics soon after login. Early in the boot I get the message "IOMMU: mapping reserved region failed" 8 times. Then boot appears to proceed as normal, at least once the nvidia blob is removed in favour of Nouveau (otherwise, forget it...).
After graphical login, the system freezes within a couple of minutes.After a text login, the system freezes within seconds with a panic, starting "BUG: Scheduling while atomic: swapper". A forum search for the IOMMU message leads to https://fedoraproject.org/wiki/Commo...IOMMU_handling but this talks about old 32-bit releases without BIOS virtualization support.

I'm struggling with my computer to get it to run a Windows 7 x64 machine as domU with VGA passthrough using Xen and Fedora 14 as dom0.
The problem is that when I enable IOMMU in BIOS, it simply freezes during boot. If booting with the dom0 pvops kernel via Xen it stops at the "IOMMU enabled" message. If I boot the regular unpatched kernel without the Xen; all I see is naught but a blinking cursor at the upper left corner.
I tried booting from the Fedora 14 liveCD and the lubuntu 10.04 liveCD and they booth freeze in a simlar fashion afer I get past their bootloaders.
The Windows 7 partition boots just fine and I can do all sorts of stuff in it (such as conducting computationally intensive tasks) without problems.

So, I was working with Ubuntu 9.10 and I wrote a C program which was working just fine. Then, I have installed Ubuntu 10.10 and tried to run this same program again. However, I get the following error: Code: Memory Mapping failed. Error: 1 Part of the code has the following: Code: volatile ulong *memory;
int fd = open("/dev/mem", O_RDWR | O_SYNC);
if (fd < 0) {
printf("Could not open memory.
");
return(0);
}
code....
Does anyone have an idea what the problem could be? I do not know if there would be any significant change between Ubuntu 9.10 and 10.10 that could be generating me this problem.

I need to connect to my company through a Cisco VPN. The Cisco client fails to build so I thought of using vpnc. I used Network manager (NetworkManager-vpnc is installed). However after setting everything up and then logging in, I get the 'VPN Connection Failed' message.

I just having to do a fresh install and get the following message to close after setting up
partitions and on clicking write to disk:
Failed to mount "524M Volume"
Method "Mount" with signature "ssas" on interface
"org.freedesktop.Hal.Device.Volume" doesn't exist.
Only option under message is close button. I'm using Fedora 14 xfce 32bit live CD. The install seems to carry on normally until done but then when I check the partitions I've setup I seem to only have the origonal uneditted default partitions.

I ran Movie Player to play .mov file, but it generate the following error message:
pa_stream_writable_size() failed: Connection terminated
The .mov file is wide screen, I am not sure if that's why the error occurred. By the way, the .mov file is several hundred megabytes and store on DVD.

In understanding with Fedora logs are trying to tell me and if I need to adjust some settings on my system to address these issues.
The system motherboard (Gigabyte GA-MA785GT-UD3H) has onboard graphics. I understand that some of the system RAM is taken up by the graphics subsystem.
Very occasionally, I am seeing Nautilus and some other apps crash with SIGSEGV errors. Also, on the couple of occasions, parts of the display started going black - minimising and maximising the window redrew the area as before. This appears to be to do with memory access issues. I have already tested my RAM, applied the latest BIOS update on the mobo. I'm trying to understand if this is some sort of memory access violation that is resulting from the Linux kernel going off and accessing the wrong parts of the RAM and if there is a way to tell it that the graphics and system areas of the RAM are separate, through BIOS settings or kernel parameters and such?
Some questions:
1. Is my system using AGP? I don't think so. I understand AGP is on its way out. So what does the below log output mean wrt AGP?
2. Which part of the log is actually describing the memory assignment for the graphics memory?
3. Would it be of any use trying iommu=noaperture here? I am trying this out, but I don't understand if it is helping in anyway.
Have done a Google search and read on AGP, iommu, shared memory for graphics, but their interaction with each other at the hardware level and how Fedora is handling this is not sinking into my dull brain.
I have put up the system configuration, BIOS settings, logs etc for your perusal here [url]. Parts that caught my attention are highlighted.
Now, onto the bits that has my attention:

No AGP bridge found

It's been awhile since I posted anything which is a good sign my install has been working well and I have been able to handle most everything. However, I'm not able to handle this issue. I recently installed F11 and everything went well. But, when trying to see my other computers on the local network, I cannot. I receive this error message: Unable to mount location Failed to receive shared list from server. I understand the message as it is obvious, but do not know how to fix it.

it's my first day of trying to figure out Linux, and I now understand why it's been largely used by the geek community.I've tried to install both xcdroast and 7zip using the console and failed miserably both times.7zip doesn't have a ./configure and xcdroast just gives me errors that I don't understandI think I need a package manager?

Since I upgrade our cluster from the FC14 to the FC15 I have a bad problem with the tftpd server. I have some thinstations booting over the network after the update the boot failed with the message "TFTP open timeout". I use an "ip alias" (cluster adress) for the tftp server (next-server in the dhcp), when I use the real ip I have no problem. I found some information about a "Service Guard environment" and an option to enable it:
"This option is required for some tftp clients. These clients reject the tftp reply received from a different IP address than the one requested when the server?s interface is configured with an alias IP address." I do not see an option like that in the tftpd server of the FC15.

I am getting an error from yum update and Kpackagekit:
[root@asus-m4n82 tylerm]# yum update
Loaded plugins: refresh-packagekit
Setting up Update Process
rpmdb: page 18816: illegal page type or format

How do I "run recovery"? Edit: Ok so it looks like I had som bad ram in my system that caused this - I found a site that told me to do this:
rm -f /var/lib/rpm/__db*
rpm rebuilddb
yum clean all
I did this but now when I try something like yum install firefox it pulls in a ton of already installed packages.

I've upgrade my hardware configuration up to 4GB of RAM. Today I've found some problems with my Ubuntu 10.10, like music stops playing or file system that became read-only. I've found this errors messages running dmesg:Code:PCI-DMA: Out of IOMMU space for xxx bytesI've tried to add "iommu=memaper=3" and "iommu=noaperture" to boot options as found with google, but problem still remains.

first, sorry for my bad english, I am german I have a problem enabling IOMMU on my MSI 970A-G45 mainboard. I need the IOMMU support for PCI passthrough in KVM ( I need my DVB pci cards in the virtual machine).
I have installed Ubuntu server 11.04 and enabled IOMMU in bios. The first strange thing is, that when iommu is enabled in the bios i cant access network or USB devices in ubuntu. Only when its disabled in bios.
Well, i tried the tutorial from here: http://www.linux-kvm.org/page/How_to...th_VT-d_in_KVM and compiled a new kernel with "Support for DMA Remapping Devices", "Enable DMA Remapping Devices" and "PCI Stub driver" enabled and installed it (based on description in wiki)

Problem: rsync to NAS gives 'rsync: failed to set times on "/media/NAS": Operation not permitted (1)'
Efforts to date.
1.Initial set up was ubuntu 10.04 on stock DNS 323 NAS. Grsync would copy file names and folders to NAS but they all were 0 bytes and no data.
2.Set up FFP on NAS, installed rsync server on NAS, and retried. Grsync now copies all the files and folders,but get the 'rsync: failed to set times on "/media/NAS": Operation not permitted (1)'
3.Grsync with -t removed (does not preserve time) works without error message, but does not keep time/date on NAS backup.
Setup: NAS is automounted with CIFS:
//192.168.1.999/NAS/ /media/NAS cifs guest,rw,iocharset=utf8,file_mode=0777,dir_mode=07 77 0 0
Reading at length seems to reveal that this issue is a permission problem. So my question is:
1.Is there a simple edit to my fstab file that would give me permission to save time/owner to my NAS?
2.Would I be able to use chown to modify the folder on my NAS to own it? ***if so -> syntax to use chown on a network drive.
3.Do I need to edit my NAS rsync server to solve this?
4.I have a 1 gig network/cards, my speeds are 4mb/sec. Is this a good speed for this type of network, or is this a bug of CiFS networks?

This affects any version of Linux I have managed to put my hands on, 32 bit as well as 64 bit, except XenServer 5.6. This does not affect Windows 7 x64, GRUB bootloaders and FreeDOS/MSDOS based boot CDs. Also, Linux boots fine with the BIOS IOMMU feature disabled.What happens is that the 64-bit Linux install, bootCD, installCD, liveCD or USB hangs almost immediately after GRUB with naught but a blinking cursor at the upper left corner. Some liveCDs manage to show some kind of boot splash before it hangs. USB peripherals such as the mouse and the USB stick gets severed at the moment of the hang. The num-lock led is on but the keyboard is irresponsive to *-lock toggles.
In the 32-bit version it takes a little longer before the hang and the USB peripherals stay on at the event of the hang, but the keyboard is irrespnsive in the same manner. It also spits out error messages.

Using the networking icon on the tray I add a PPTP connection, set it up but I receive a message 'VPN connection failed'. Googling it up I tried changing a setting called 'refuse-eap' to 'yes' but it doesn't seem to work. Here's the result from the log file:

the laptop of my friend runs ubuntu through wubi. The system suddenly freezed and she restarted it manually. After doing a check disk and automatically repaired some packages(unfortunately she doesn't remember what exactly, only just inode information appeared), she can't log in as when she types her username and password the answer is authentication failed. We tried to change the password through recovery mode but nothing happened.
1. Do you have something to propose to solve the login problem?
2. If not how can i access and back up her ubuntu documents through windows?
