Created attachment 344196 [details] emerge --info Hi, since world update on 30.3.2013 with 300+ updated packages including udev-200, and whole KDE environment v4.10.1 but NOT including xorg-server, I am experiencing regular X restarts that conclude in kdm login screen being displayed. It seems to me that it is somehow related to an usb device reconnection that kernel outputs: tail -n 50000 /var/log/messages | grep -B3 unexpectedly Apr 3 12:23:21 HotT410s polkitd[1948]: Unregistered Authentication Agent for unix-session:/org/freedesktop/ConsoleKit/Session6 (system bus name :1.124, object path /org/kde/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus) Apr 3 12:23:21 HotT410s su[4526]: pam_unix(su:session): session closed for user root Apr 3 12:23:21 HotT410s kdm[2452]: X server for display :0 terminated unexpectedly -- Apr 3 12:51:38 HotT410s kernel: [66799.522443] usb 1-1.5.2.2: unlink qh8-0601/ffff8801e44ea480 start 7 [1/2 us] Apr 3 12:51:38 HotT410s polkitd[1948]: Unregistered Authentication Agent for unix-session:/org/freedesktop/ConsoleKit/Session7 (system bus name :1.148, object path /org/kde/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus) Apr 3 12:51:38 HotT410s kdm[2452]: X server for display :0 terminated unexpectedly -- Apr 3 12:53:00 HotT410s dhcpcd[2352]: wlp3s0: leased 195.113.219.162 for 1800 seconds Apr 3 13:00:20 HotT410s kernel: [67320.598866] usb 1-1.5.2.2: unlink qh8-0601/ffff8801e44ea480 start 7 [1/2 us] Apr 3 13:00:20 HotT410s kdm[2452]: X server for display :0 terminated unexpectedly -- Apr 3 13:23:00 HotT410s dhcpcd[2352]: wlp3s0: leased 195.113.219.162 for 1800 seconds Apr 3 13:23:17 HotT410s kernel: [68693.940288] usb 1-1.5.2.2: unlink qh8-0601/ffff8801e44ea480 start 7 [1/2 us] Apr 3 13:23:17 HotT410s kdm[2452]: X server for display :0 terminated unexpectedly I am not sure what usb device the "1-1.5.2.2" id stands for and how to check it. The message "unlink qh8-0601/ffff8801e44ea480 start 7 [1/2 us]" is nothing new in messages, it was present almost daily even before the world update, but never causing xorg server restart. I would be really glad if you could point me to right direction since I am not sure where to start digging or which package to try downgrade/upgrade. I include some logs that might be helpful. Thanks Jiri Horky

See http://www.gentoo.org/proj/en/qa/backtraces.xml and http://www.x.org/wiki/Development/Documentation/ServerDebugging for instructions on how to debug X with gdb, please note that you will need to have Xorg and the libraries listed in the backtrace with -ggdb as instructed in the first link in order to obtain a meaningful backtrace. As for the USB device, I think you can figure out which one that is by running `dmesg | grep usb` if the first lines are still in your log, otherwise you will need to increase the log_buf_len kernel parameter. So, in order to proceed here we will need a backtrace for X.
OK, so the device seems to be a Logitech mouse. Here is the backtrace when it happens: Program received signal SIGBUS, Bus error.

It starts to drive me crazy as it restarts every second hour. Last time it happened, I almost had this update written... Thanks Jiri
So you have modern userland (unstable xf86-video-intel) with old kernel. This combination is usually not working well. If the issue persists after upgrading to latest ~arch kernel, best open a bug report upstream at https://bugs.freedesktop.org/ and include your stack trace there. The USB issues are not related to the X server crash.
Hi, you are right, I completely forgot that I have an unstable version of intel drivers (yes, I know it is not a good idea to list a package in .keywords without a version :). Thank you for pointing that out. Going back to stable, the problem is gone. My goal is to run stable version of everything if it is really stable so I will stick with this setup. One more thing: the usb problem with the mouse was actually the trigger that caused the X restart (SIGBUS) so I think it is a bit related at least. Regards Jiri Horky
Hopefully fixed long ago. If not please file a bug upstream.
