I tried both modular X and Xorg 6.8/kernel 2.6.15 and 2.6.16 and get the same bug(probably another line with the .15 kernel through) when I end my X session to get back to gdm. I also tried setting AlwaysRestartServer=true in /etc/X11/gdm/gdm.conf but that didn't make any difference. kernel BUG at arch/i386/mm/pageattr.c:152! invalid opcode: 0000 [#1] PREEMPT Modules linked in: fglrx agpgart smbfs via686a w83781d hwmon_vid i2c_isa i2c_via pro parport_pc lp parport snd_seq_midi snd_emu10k1_synth snd_emux_synth snd_seq_ virmidi snd_seq_midi_emul snd_pcm_oss snd_mixer_oss snd_seq_dummy snd_seq_oss sn d_seq_midi_event snd_seq video thermal processor fan button tun snd_emu10k1 snd_ rawmidi snd_ac97_codec snd_ac97_bus snd_pcm snd_seq_device snd_timer snd_page_al loc snd_util_mem snd_hwdep snd tuner tvaudio msp3400 bttv video_buf firmware_cla ss compat_ioctl32 i2c_algo_bit v4l2_common btcx_risc ir_common tveeprom i2c_core videodev psmouse rtc CPU: 0 EIP: 0060:[<c01100e1>] Tainted: P VLI EFLAGS: 00013082 (2.6.16-gentoo-r1 #1) EIP is at __change_page_attr+0xcb/0x17c eax: 1e8001e3 ebx: 1eb20000 ecx: c1006f20 edx: 00000163 esi: c0379de8 edi: deb20000 ebp: c1000000 esp: cc86fe78 ds: 007b es: 007b ss: 0068 Process X (pid: 14680, threadinfo=cc86e000 task=debc9070) Stack: <0>c13d6400 00000008 00000000 00003246 c01101bb c13d6400 00000163 deb902c 0 e19c0000 e1a64d60 00000000 c010fe51 c13d6300 00000009 00000163 e1a64d60 00000003 e19fcd7d e19c0000 c13d6300 00000008 00000163 e1a64d60 00000000 Call Trace: [<c01101bb>] change_page_attr+0x29/0x5a [<c010fe51>] iounmap+0xb2/0xe9 [<e19fcd7d>] agp_generic_free_gatt_table+0x62/0xce [fglrx] [<e1a02de0>] agp_backend_cleanup+0xc/0x4a [fglrx] [<e1a060db>] __ke_agp_uninit+0xe/0x24 [fglrx] [<e1a0e565>] _firegl_release_agp+0x15/0x140 [fglrx] [<e1a10da5>] firegl_takedown+0x335/0xc40 [fglrx] [<e1a100ff>] firegl_release+0x12f/0x190 [fglrx] [<e1a031cb>] ip_firegl_release+0xd/0x10 [fglrx] [<c0149061>] __fput+0x83/0x142 [<c0147ce1>] filp_close+0x4c/0x55 [<c0147d43>] sys_close+0x59/0x7c [<c01024ab>] sysenter_past_esp+0x54/0x75 Code: 56 e8 f4 fe ff ff 89 d9 83 c4 0c 8b 01 89 ca f6 c4 40 74 03 8b 51 0c ff 42 04 eb 17 84 c0 78 0b 0b 5c 24 18 89 1e ff 49 04 eb 08 <0f> 0b 98 00 e1 99 2c c0 8b 01 f6 c4 04 0f 85 97 00 00 00 8b 01 <6>note: X[14680] exited with preempt_count 2 emerge --info: Portage 2.1_pre7-r4 (default-linux/x86/2006.0, gcc-3.4.5, glibc-2.3.5-r3, 2.6.16 -gentoo-r1 i686) ================================================================= System uname: 2.6.16-gentoo-r1 i686 AMD Athlon(tm) Processor Gentoo Base System version 1.6.14 distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled ] ccache version 2.3 [disabled] dev-lang/python: 2.3.5-r2, 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=athlon-tbird -O2 -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3.5/env /usr/kde/3.5/share /config /usr/kde/3.5/shutdown /usr/kde/3/share/config /usr/share/X11/xkb /usr/sh are/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/eselect/compiler /etc/gconf /etc/splash /etc/terminfo /etc/env.d" CXXFLAGS="-march=athlon-tbird -O2 -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distcc distlocks metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="ftp://mirror.nutsmaas.nl/gentoo/ http://ftp.easynet.nl/mirror/ge ntoo/ http://www.gigaload.org/gentoo.org/ http://mirrors.sec.informatik.tu-darms tadt.de/gentoo/ http://gentoo.mirror.sdv.fr" LINGUAS="sv" MAKEOPTS="-j11" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="x86 3dnow X alsa apache2 apm avi berkdb bitmap-fonts cddb cdr cjk cli crypt ctype cups dba divx4linux doc dri dvd emboss encode esd expat fam fastbuild foo maticdb force-cgi-redirect fortran ftp gd gdbm gif gimpprint glibc-omitfp glx gp m gstreamer gtk gtk2 hal icq imlib ipv6 isdnlog jpeg kde libg++ libvisual libwww live memlimit mikmod mmx motif mp3 mpeg msn musicbrainz nas ncurses network nls nptl nptlonly ogg opengl oss pam pcre pdflib perl pic png posix ppds pppd pytho n qt quicktime rdesktop readline samba sdl session simplexml soap sockets spell spl ssl tcltk tcpd tokenizer truetype truetype-fonts type1-fonts udev unicode us b v4l v4l2 vorbis xml xmms xprint xsl xv xvid zlib elibc_glibc input_devices_key board input_devices_mouse kernel_linux linguas_sv userland_GNU video_cards_fglrx video_cards_ati video_cards_vesa video_cards_v4l" Unset: ASFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLA GS My ati section in Xorg.conf #

mind trying to reproduce the problem without the ati driver (fglrx) loaded?
This is a fglrx bug
(In reply to comment #2) > mind trying to reproduce the problem without the ati driver (fglrx) loaded? > All works fine with MESA driver
Reopen if you can reproduce with up-to-date ati-drivers.
