Hello Everybody,
I have some trouble with my ArchLinux Installations. The Systems are very unresponsive (long waiting on gui interaction). In Htop I can see a high CPU wait time,and a high cpu load, but in iftop no IO load is on the drives. I have these Probelem with 3 Arch Installations. These systems run kf5. All installations runs ArchLinux Stable (not testing), and the Installations are up to date. On my parents PC the problem only appear after the last update. I have copy the output to pastebin. http://pastebin.com/E4xnQKhJ
For me it looks like a graphics bug. I have downgraded the kernel to an older version but it does not resolve the problem. Maybe anybody know something about that. Or have an larger expertise in investigating this bug.
I use archlinux now longer than six years. I have solved much problems. But this bug makes me crazy..
Are you sure there was no IO? USB drives can block the whole system for long periods since a couple major kernel versions, similar to Windows blocking with certain device drivers.
