Hello everyone,
I noticed that my imx8mp based board (TQMa8MPxL, not yet mainline) locked up
during boot in linux-next. I bisected it down to commit [1].
I found out that disabling 'fec' and 'eqos' (both ethernet controller) nodes
in DT resulted in booting Kernel, alas NFS boot failed eventually obviously.
Reverting make things working again.
I have no idea which clock is the actual culprit here and how to fix it. I
just wanted to make you aware of this issue.
Best regards,
Alexander
