From: Jason Hunt To: freebsd-current@freebsd.org Content-Type: text/plain; charset=UTF-8 X-Content-Filtered-By: Mailman/MimeDel 2.1.22 X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.22 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 30 May 2016 03:05:03 -0000 Intermittently after building world/kernel and installing kernel, upon reboot I sometimes get stuck at: >> FreeBSD EFI boot block Loader path: /boot/loader.efi Initializing modules: ZFS UFS Probing 35 block devices ... done ZFS found the following pools: zroot UFS found no partitions Consoles: EFI console And that's it. Often times it's fixed by rebooting, but sometimes it takes numerous attempts. Patience and cold boot vs warm boot doesn't make a difference and unfortunately there doesn't seem to be any pattern as to how it fixes itself. Eventually the full boot screen appears and I can get in to single user mode to continue installing world. I've only been following current for a couple of months, so I can't say if this is a new problem, but it's happened most (but not every) times I've rebuilt the system. Normal day-to-day rebooting doesn't give me any issues; only when rebuilding. Do I potentially have a buggy EFI firmware (motherboard is an ASUS P8B75-M with latest firmware), or could it be a FreeBSD issue? I'm not even sure how to try diagnosing this or what information would be helpful? Any suggestions are appreciated. - Jason
