File: dmesg
To reproduce: 1) Install Fedora Server 23 on an Intel platform which supports VT-d, with all available updates. 2) Configure system for VT-d/IOMMU. 3) Install guest domain of any OS (Both Fedora 24 and Windows 10 have been tested and found to elicit the error) and configure with PCI-passthrough devices from the host. 3a) I pass through a USB hub, NVidia GeForce GTX 960, and an onboard audio controller). To the USB hub is connected a mouse and a keyboard, and sometimes Logitech game controllers (F310s), but this particular bug report demonstrates an occurrence with only mouse/keyboard attached. 4) Start and shut down the guest domain. 4a) I can usually do this only once or twice before the issue appears. I have never been able to do it three times without a crash. This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Well, it appears that the last Kernel version to be released for Fedora 23 will be 4.7 variety. The latest 4.7.10 kernel still exhibits the bug described above, and Fedora 23 is reaching EOL soon (as noted in the comment above) so it looks like the bug will be permanent with Fedora 23. That said, upgrading to Fedora 24 and Kernel 4.8 does appear to resolve the issue. So, good news! Upgrade away. (In reply to Dylan Combs from comment #4) > Well, it appears that the last Kernel version to be released for Fedora 23 > will be 4.7 variety. Fedora 23 has 4.8.8-100.fc23 as the latest stable update. Either way, glad it's working for you. Ah, thanks for the correction; I'll just change it to fixed in the current release. |
