I had a lot of freezes, reboots and kernel panics the last days. Really annoyed I started searching and found https://bugzilla.redhat.com/show_bug.cgi?id=2420039 First try was rolling back my #silverblue #universalblue image to a version from October last year. There the issue was not occuring kernel 6.17. So I added another workaround to my image and downgrade amdgpu firmware, as described in the bugzilla. I'm running kernel 6.18.7 with downgraded firmware about 2 days now and no freeze or kernel panic happened.
