I got Xorg lockups with an ATI Radeon 9250, xorg 6.8.2-r6, linux 2.6.15-r1. After upgrade to xorg 7.0-r1 and linux 2.6.15-r4 I got a lockup as well. The lockup usually occurs while a xscreensaver hack is active. I got a lockup outside of xscreensaver earlier, and switched xscreensaver blanking off for testing. With xorg 6.8.2 the lockup occured in the hypercube hack a few times, and the hack was apparently displayed incorrectly, there were some random line segments scattered on the screen in addition to the cube. The machine was either inacessible or there was an X process running in a tight loop and unkillable, with no way to change what is displayed on the screen. With xorg 7 I got a lockup in polytopes. I cannot tell if it is displayed correctly. after the lockup polytopes was the process that used most cpu time, when I killed it X used most cpu time. It was again unkillable. When X is looping and cannot be killed top says there is >99% system cpu time. 00:00.0 Host bridge: Intel Corporation 82845 845 (Brookdale) Chipset Host Bridge (rev 03) 00:01.0 PCI bridge: Intel Corporation 82845 845 (Brookdale) Chipset AGP Bridge (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 12) 00:1f.0 ISA bridge: Intel Corporation 82801BA ISA Bridge (LPC) (rev 12) 00:1f.1 IDE interface: Intel Corporation 82801BA IDE U100 (rev 12) 00:1f.2 USB Controller: Intel Corporation 82801BA/BAM USB (Hub #1) (rev 12) 00:1f.3 SMBus: Intel Corporation 82801BA/BAM SMBus (rev 12) 00:1f.4 USB Controller: Intel Corporation 82801BA/BAM USB (Hub #2) (rev 12) 00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 Audio (rev 12) 01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 PRO] (rev 01) 01:00.1 Display controller: ATI Technologies Inc RV280 [Radeon 9200 PRO] (Secondary) (rev 01) 02:08.0 Ethernet controller: Intel Corporation 82801BA/BAM/CA/CAM Ethernet Controller (rev 03) 02:0a.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01) 02:0b.0 Ethernet controller: Digital Equipment Corporation DECchip 21140 [FasterNet] (rev 22) Portage 2.1_pre4-r1 (hardened/x86/2.6, gcc-3.4.4, glibc-2.3.5-r2, 2.6.15-gentoo-r4 i686) ================================================================= System uname: 2.6.15-gentoo-r4 i686 Intel(R) Pentium(R) 4 CPU 2.00GHz Gentoo Base System version 1.12.0_pre15 dev-lang/python: 2.3.5-r2, 2.4.2 sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r6 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="-O2 -march=pentium4 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/share/X11/xkb /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O2 -march=pentium4 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks maketest nostrip sandbox sfperms strict" GENTOO_MIRRORS="ftp://ftp.sh.cvut.cz/MIRRORS/gentoo http://distfiles.gentoo.org http://www.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage//packages/x86/" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage/" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X accessibility aim alsa apache2 berkdb crypt cups debug dlloader dmx doc dri examples foomaticdb fpx gimpprint glitz gpm gs hardened icq icu ipv6 irc jabber java jbig kerberos krb4 ldap libclamav mmx mono mozilla mpeg msn nls nsplugin offensive opengl pam pic ppds readline samba sasl spell sse ssl svg tcpd threads truetype truetype-fonts unicode userlocales wmf x86 xv zlib elibc_glibc input_devices_evdev input_devices_mouse input_devices_keyboard input_devices_kbd input_devices_joystick kernel_linux userland_GNU video_cards_mga video_cards_radeon video_cards_ati" Unset: ASFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, LANG, LC_ALL, LDFLAGS, LINGUAS
Please file this at bugs.freedesktop.org in the xorg product (or the DRI product if it only locks up on OpenGL apps), and post the URL here so we can track it. Thanks!
hmm, it was possibly the card. I replaced it with another card of the same type, and removed the dvb card to improve airflow. No lockups so far.
Alrighty, we'll re-classify this bug then...
Marking as INVALID since it might not be a bug. Feel free to re-open if the problem comes back.
ok, I got another lockup. https://bugs.freedesktop.org/show_bug.cgi?id=5986
reported at freedesktop.org
Much thanks.
