[Bug 1451277] Re: Extremely high IOWait and processes hungs after utopic->vivid upgrade with Iomega Zip drive (IDE)
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

>From LKML conversation, fix https://lkml.org/lkml/2014/11/20/581 is not likely to be applied upstream, because it probably just papers over the real bug. The real issue appears with the patch series "scsi: convert host_busy to atomic_t" that causes regressions on some hardware configurations. Might not be due to this series either, but to some other race that this change helps triggering. I wonder if papering over can be acceptable downstream. -- 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

Bisected. Bug seen after commit 045065d8a300a37218c548e9aa7becd581c6a0e8 [SCSI] fix qemu boot hang problem. Actually, the problem is not with that commit that is perfectly fine. That commit merely lets the real bug be triggered. Real bug is with scsi host lock and likely to be triggered by mixing a slow and a fast device on the same IDE/SATA channel.

[Bug 1451277] Re: Extremely high IOWait and processes hungs after utopic-vivid upgrade with Iomega Zip drive (IDE)
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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

3.17.0 impossible to test because, for some reason, it fails to boot to X with the nvidia proprietary driver, so it is hard to test in realistic conditions. In any case, I would say that the issue has been introduced in the 3.16 - 3.17 transition.

I would also rise priority, since the issue - makes it often impossible to shut down the machine cleanly, requiring a hard reset which may result in data loss; - I imagine that it can make it quite hard to install security updates from ubuntu as any update of the kernel package tends to result in the system hanging at the make initramfs phase, that probably queries all system drives. -- 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
