Description Pierre Ossman 2019-10-08 15:21:24 UTC
The upgrade to the 5.2 series of the kernel has unfortunately made my system unusable. After resuming the system from suspend the display goes green and is unresponsive locally. It is still up though so I was able to reach it via the network and get some logs out of it.

Tested bad kernels:

5.2.15-200.fc30
5.2.9-200.fc30

Known good kernels:

5.0.17-300.fc30
5.1.18-300.fc30
5.1.20-300.fc30

Found some other bug reports both here and with Red Hat with similar warnings in dmesg, but they seem to be failing right away and not after a suspend. So I'm not sure if it's the same issue.

But report at Red Hat:

https://bugzilla.redhat.com/show_bug.cgi?id=1754252

(includes dmesg)

Can you bisect?
Comment 2 Pierre Ossman 2019-10-09 05:15:09 UTC
Not easily unfortunately as I've only been using Fedora kernels, so I don't have a build environment set up.
