Description Robbie Harwood 2017-04-27 00:09:46 UTC

With kernel-core-4.11.0-0.rc7.git3.1.fc27.x86_64, I get this traceback which halts boot:

https://rharwood.fedorapeople.org/screenshots/2017-04-24-153656_3840x1080_scrot.png

This behavior doesn't occur with 4.11.0-0.rc6.git3.1.fc27.x86_64.

(The screenshot is from the fc26 versions, which exhibit the same behavior.

Comment 1 Laura Abbott 2017-04-27 01:06:15 UTC

Can you test with -rc8? Someone on IRC reported similar behavior on -rc7 and reported it was fixed on -rc8.

Comment 2 Robbie Harwood 2017-04-27 02:32:58 UTC

Sure thing.

4.11.0-0.rc8.git2.1.fc27.x86_64 is good, as is 4.11.0-0.rc8.git0.1.fc26.x86_64.  (I've also given karma on the bodhi.)

Thanks!

Comment 3 Adam Williamson (Red Hat non-Fedora) 2017-04-28 00:19:46 UTC

Saw something similar in openQA testing of virtio-scsi disks when RC7 landed in Fedora 26. Testing with a couple of custom-built images confirms this was caused by RC7 and seems to be resolved in RC8.

Comment 4 Fedora Update System 2017-04-28 00:29:28 UTC

kernel-4.11.0-0.rc8.git0.1.fc26 has been submitted as an update to Fedora 26. https://bodhi.fedoraproject.org/updates/FEDORA-2017-847f5e68b1

Comment 5 Fedora Update System 2017-04-28 14:36:09 UTC

kernel-4.11.0-0.rc8.git0.1.fc26 has been pushed to the Fedora 26 stable repository. If problems still persist, please make note of it in this bug report.

Comment 6 Laura Abbott 2018-02-28 03:36:48 UTC

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale. The kernel moves very fast so bugs may get fixed as part of a kernel update. Due to this, we are doing a mass bug update across all of the Fedora 26 kernel bugs.
 
Fedora 26 has now been rebased to 4.15.4-200.fc26.  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 have moved on to Fedora 27, and are still experiencing this issue, please change the version to Fedora 27.
 
If you experience different issues, please open a new bug report for those.

Comment 7 Robbie Harwood 2018-02-28 18:42:24 UTC

(I think this bug was supposed to have been closed per comment#5.)
