[solved] Xorg 1.6 segfault

Since xorg-server 1.6 was released, X has been dying on me... I believe I can always reproduce this by switching to a virtual console and back to X.  Once X dies, it's pretty much over; computer won't respond to anything except magic sysreqs.

Re: [solved] Xorg 1.6 segfault

What video card/driver? I wonder if you can disable write-combining, not that you should have to, but it could be a bug.

Re: [solved] Xorg 1.6 segfault

<_< well no... I've been ignoring the kernel 2.6.29 package since broadcom-wl in AUR hasn't been updated to support it yet

Edit: looks like the kernel upgrade fixed it, guess you can't mix-and-match tongue

Re: [solved] Xorg 1.6 segfault

same problem here, but i was waiting for qc-usb.

on thing i wanted to mention in case someone else gets this problem, once i updated the kernel and rebooted, my display was garbled. i had to switch to xf86-video-intel-legacy to fix this (i'm running an intel i810 i believe)

Re: [solved] Xorg 1.6 segfault

I got a similar stacktrace, see http://bbs.archlinux.org/viewtopic.php?pid=538309 . For me, adding "nopat" as a kernel boot parameter solved the issue. Don't know what or how, though ..
