Hi, Thanks for the bug report. Is the host F28, the guest F28, or both? Can you please attach the dmesg logs from the host and guest? Created attachment 1423948 [details]
dmesg of the host with working 4.15 kernel
Created attachment 1423966 [details]
dmesg of the guest centos 7.4.1708
Created attachment 1423970 [details]
dmesg (journalctl -k -b -1) of the host with broken kernel 4.16.2
There doesn't look to be anything exciting in the logs, so your best bet is to bisect this. https://docs.fedoraproject.org/quick-docs/en-US/kernel/troubleshooting.html#bisecting-the-kernel should get you started if you've not bisected the kernel before. Please let me know if you have any questions. Thanks *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 28 kernel bugs. Fedora 28 has now been rebased to 4.17.7-200.fc28. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those. *********** MASS BUG UPDATE ************** This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 5 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously. |
