I have tried to look into the issue, but I am encountering a situation that is extremely weird. Hence I hope that someone might be able to help.
The latest kernel that works from the ubuntu mainline ppa repo is 3.16.7-031607_3.16.7-031607.201410301735 Kernel 3.17.0-031700_3.17.0-031700.201410060605 already shows the issue. However, if I try to compile myself 3.17 from Linus following the instructions in https://wiki.ubuntu.com/KernelTeam/GitKernelBuild I get: - a kernel that is clearly completely different in configuration from that in the ubuntu ppa mainline (different package names, much much larger kernel image package) and, most important, - a kernel that apparently does not show the IOWAIT issue. At the same time, I am recently experiencing all sort of issues with nvidia 304 and kde plasma 5 causing continuous hangs in plasmashell even if compositing is off, so it is quite difficult to properly test for me. -- 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 with Iomega Zip drive (IDE) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1451277/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
