3.16.7-031607-generic seems to have no issue. 3.19.0-18-generic has the issue 4.0.4-040004-generic cannot be tested because it is impossible for me to use X with it (the nvidia proprietary driver 304 does not work with it and Kwin does not work on my hardware without it).
This is already good news since staying with the utopic kernel seems to be a workable workaround. In the future I'll try 3.17 and 3.18 if possible. Will take some time since the machine is only rarely used after the vivid upgrade as plasma 5 is too immature for regular use. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1451277 Title: Extremely high IOWait and processes hungs after utopic->vivid upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1451277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
