Description of problem: Asus P5E-VM-HDMI motherbard, using onboard G35 GMA with HDMI output, Xorg works when machine has 1GB memory installed, fails with 4GB or 8GB. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg.x86_64 1.4.99.901-29.20080415 xorg-x11-drv-i810.x86_64 2.2.1-24.fc9 How reproducible: 100% Steps to Reproduce: 1. install 4GB or more of memory 2. boot machine with rhgb enabled Actual results: With the extra memory, the machine boots, the text console displays ok, xorg starts for rhgb and is displayed ok, when xorg restarts for gdm, the display is left full of blocks of "random" pixels and xorg crashes, the machine however is not dead and will respond to ctrl-alt-del, or to ssh. Expected results: onboard graphics are usable with any amount of memory Additional info: It seems this occurs only on the *second* time of initialising xorg, perhaps it is the shutdown of xorg which is the problem? If rhgb is enabled, the instance of xorg for rhgb succeeds, then the instance of xorg for gdm fails. If rhgb is disabled, then the first instance of xorg runs for rhgb and it succeeds, but if it is killed it will not restart. If the machine is started in runlevel3, then the first startx succeeds, but if that is killed, a second startx fails.

i can confirm this problem with a radeon hd 2400 pro (rv610) card i also opened a bug https://bugzilla.redhat.com/show_bug.cgi?id=450432 should we close one?
but i have got the 32bit version of fedora installed
Although they both seem related to 4GB memory, on my machine with the intel driver it crashes xorg, yours with the radeon driver reboots the machine (kernel panic?) I'd rather see some comment from an ajax and/or arlied before closing either of them.
I found out something more about this problem. could this be an mtrr problem? i have attached a dmesg file and my gdm log in both there are mtrr problems like: error setting MTRR (base = 0xf0000000, size = 0x08000000, type = 1) Invalid argument (22)

i found a solution for my problem. i dont know if this is a nice idea... i disabled the memory remap feature in my motherboard bios. ofter that my ati radeon 2400 pro works
I have this problem on a Dell Optiplex 745. Didn't realize it was a 4GB problem.
I'm reasonably sure I'm seeing this bug, rather than bug #450247. Commonalities: - machine locks hard on spawning of second X server (first is fine), e.g. GDM after RHGB; if I turn RHGB off it crashes if log out - which restarts X - 4GB RAM Similarities: - Radeon HD 2400 XT - Dell Optiplex 755 I also see: error setting MTRR (base = 0xd0000000, size = 0x10000000, type = 1) Invalid argument (22) in my GDM log, and: Aug 29 13:58:17 keyop kernel: mtrr: type mismatch for d0000000,10000000 old: write-back new: write-combining in /var/log/messages. I've updated to the latest available BIOS. I can't find a memory remap feature in the BIOS. It'll be tricky to test removing a stick of RAM (but possible if needed) - I'll have to get alarms disabled etc. I'm running a vaguely usable machine by disabling RHGB - as long as I don't log out!
Ha. I meant, of course, that I see more in common with this bug than bug #450432.
My Bug report in #455127 seems to have the same problem. I also have the same motherboard and 4G of ram as the original reported.
This has been resolved for me since I applied the latest F9 updates. I can't see an xorg package amongst them, so I think it must be the kernel update that fixed it (to kernel-2.6.26.3-29.fc9.x86_64). Booting back into kernel-2.6.25.14-108.fc9.x86_64 causes the crash again.
I am having this problem again with kernel-2.6.26.5-45.fc9.x86_64. I can run X exactly once between reboots. Optiplex 745.
As a workaround, try limiting memory to 4GB with the kernel option 'mem=4096M' in grub.conf. Looks like a lockup in drm.
In case it helps narrow the problem down: just to note that I'm *not* experiencing the problem again having rebooted into kernel-2.6.26.5-45.fc9.x86_64. An Optiplex 755 with Radeon HD 2400 XT and 4GB RAM. I'm not using any kernel mem= options.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
