Hi, I forgot to report: the Wily kernel does not have the issue. Only the Vivid kernel has it.
As a matter of fact, according to conversation I had with one of the kernel developers, the issue may be due to a race. The more modern kernels do not seem to trigger the problem. I cannot test the most recent ubuntu kernel in the live image right now because the machine where I have the issue is currently packed in a box in view of a relocation. But I'll test as soon as it is up again. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
