Created attachment 421498 [details] Xorg logfile taken after reboot Description of problem: Every once in a while, X freezes - meaning, i can still move the mouse but i can'T click anywhere and the keyboard also doesn't respond. i can still ssh in, where top gives me Xorg at 100% cpu load (meaning 1 core). i did a reboot and took the Xorg.0.log.old (attached). the main problem seems to be this line: [ 21178.584] [mi] EQ overflowing. The server is probably stuck in an infinite loop. dmesg gave me something about a btusb error, unfortunately i didn't save it and the dmesg log was gone after the reboot :-( the freezes used to occur 2-3 times a day but seemed to stop after i moved from firefox to chrome (and they did for about a week), but now here we go again... (chrome was running in background). Version-Release number of selected component (if applicable): How reproducible: unfortunately, i don't know. Steps to Reproduce: 1. 2. 3. Actual results: Xorg uses 100% cpu on one core and freezes Expected results: Additional info:
