Xorg lockup issues have been reported for months in this forum thread: http://forums.gentoo.org/viewtopic-t-334436-highlight-x+lockups.html There is a known issue with the 6.8.2 (and earlier, I think) Xorg server directly accessing PCI config space which can result in hardware lockups. Details of the issue and patches to correct the problem can be found here: https://bugs.freedesktop.org/show_bug.cgi?id=2880 In the interest of possibly correcting the long-standing lockup issues of gentoo Xorg users and fixing the current, broken Xorg server, the latest patch provided in the freedesktop bug report should be added to the current xorg-x11-6.8.2 ebuild. That patch can be found here: https://bugs.freedesktop.org/attachment.cgi?id=3382 I added that patch to the existing xorg-x11-6.8.2-r4 patch package and rebuilt the Xorg server. The patch applied cleanly, and the server built as expected. Only time will tell whether it resolved the intermittent lockup issues I've been experiencing since March. Reproducible: Didn't try Steps to Reproduce: 1. This is an intermittent issue that is difficult, if not impossible, to reproduce consistently. Intermittent, inconsistent lockups could, however, be a byproduct of the Xorg server playing around with PCI configuration registers behind the kernel's back. 2. 3. Actual Results: In my case, the lockups have resulted in a complete system freeze. No mouse or keyboard, no magic SysRq, no ssh access -- the only way to regain control of the system is by pushing the reset button. As the above-cited forum thread indicates, other users have reported being able to move the mouse and access their machines via ssh. Expected Results: Worked.

I just ran into this problem with xorg-x11-6.8.99.15-r4. About once every 2 minutes the machine would completely lockup only when X was running. Applied the patch listed as "Use system method for byte/word accesses (take 3)" (this seems to be the one that got applied to the Xorg CVS) Everything seems to be running fine now. It would be real nice to get this patch applied to the default ebuilds.
Actually, take3 isn't in CVS yet but it soon will be. When it is I'll add it.
Just to clarify things, it appears that the finalized patch for this issue is the last one in the list of attachments for the bug report: "Patch to implement byte and word level pci config access". That is also the patch that I have linked in my original comment. Please note, however, that in my case the patch did not resolve the lockup issue I was experiencing. I am now running the stock xorg-x11-6.8.2-r4 from portage. This is sooooo frustrating...
Hmm, it would appear you have a different problem then. Have you tried 6.8.99.15?
This has been applied upstream. If I make another 6.8.2 patchset I plan to include this patch.
I've experienced this bug after I emerged xorg-x11-6.8.2-r6 upgrading from xorg- x11-6.8.2-r1. No mouse, no keyb, no vt switching possible and no external ssh access. I downgraded to xorg-x11-6.8.2-r4 and everything is fine.

6.8.2 won't be receiving any more non-security changes, and this bug doesn't apply to 7.0.
