I have only some small effekts running. I have tested if the desktop effekt could the problem and disabled all of them. But nothing solved it. I can understand when the desktop effekts slow down the system. But when I hear Music. It stops playing. Video Stops playing. Website loading stops. Only I can move the mouse cursor. The hang time is mostly 30sec. But sometimes it takes much longer. On my desktop with the nvidia card. I am running the propertry driver from nvidia. I had run memtest on all machines and a long smart self test on all drives. No Problem appeared. The log files does not provide any Information about the slow responding system. Or I dont find them. The only answer I get is in dmesg from Akonadi. INFO: task akonadi_imap_re:25437 blocked for more than 120 seconds. Tainted: P C O 4.4.5-1-ARCH #1 "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
