I am getting a KDL on boot on hrev58548 on my x86_64 VMWare.
See the following ticket for more details: #19373 (KDL on boot on hrev58548) – Haiku
I assume this will be a quick fix, but as a warning, I do not recommend upgrading to the (current latest) hrev58550 nightly image.
It is probably a good idea to hold off updating until this issue has been resolved.
Thanks for listening.
