It boots fine with current Fedora IoT 34 nightlies, but kernel crashes are very regular (sometimes recoverable, sometimes not), which looks to me like the same problem that Armbian builds have, logs seem to point to an issue with the dmc frequency. I've compiled an excerpt of interesting looking logs from a couple of boots here (you should be able to comment on the doc as well): https://hackmd.io/@lorbus/SyXTj0lXu Please take a look and let me know what you think.
