hardware is early 2011 15" macbook pro, further info at https://gist.github.com/dch/22c28211c539a6d612a4 incl dmesg, hardware specs and file-devinfo-vr-log etc. Further testing shows that any non-CD boot method (e.g. dd of FreeBSD-11.0-CURRENT-amd64-20140714-r268622-mini-memstick.img or similar) to a spare USB disk or SDXC card) freezes at exactly the same place, i.e. nothing to do with installer itself, but the boot process. At the loader(8) prompt, can you do 'set kern.vty=vt' and see if that changes the behavior? yup, adding the following:
set kern.vty=vt
boot_verbose="YES"
gets us all the way to mountroot>
mountroot is failing as it always is trying to load ufs:/dev/ufs/FreeBSD_Install and returns error 19. Looks like the installer CD/image presumably.
trying again with:
set kern.vty=vt
boot_verbose="YES"
load zfs
vfs.root.mountfrom="zfs:zroot"
vfs.root.zfs.debug="1"
produces a fair bit more output but fails to find/load init.
thanks for vt protip from @gjb! This now boots using a more common sense path: vfs.root.mountfrom="zfs:zroot/ROOT/default" If you point me in the right direction, I'll add a documentation note for these 2 tweaks. Would you mind attaching the dmesg from your (working) verbose boot? Something rather strange is going on here -- the "Start @ 0xffffffff802db000" message indicates a (U)EFI boot, that should automatically select the vt(4) console and kern.vty=vt should not be necessary. Created attachment 145160 [details] dmesg dmesg from uefi boot to zfs. some notes: zroot is on its own drive, on a zfsosx-created partition (so OSX doesn't get surly with the partition types) and the original FreeBSD-created zpool snapshotted and recursive send/received. the system boots via refind http://www.rodsbooks.com/refind/ locating the EFI FAT partition on the other drive. The only change to the Apple EFI partition is to copy in ./EFI/freebsd/boot1.efi booting requires 3 changes: set kern.vty="vt" load zfs set vfs.root.mountfrom="zfs:zroot/ROOT/default" Setting these in loader.conf (either in ./EFI/freebsd/ or on zfs) has no effect. BTW I'd love to know how to set `mode 2` in loader.conf as well instead of the small default quadrant in the middle of the EFI console. PEBKAC. An older FreeBSD boot .img had been dd'd to another disk partition. It turns out that UEFI code will pick up the first available image it recognises and boots from that, and not the loader.efi and loader.conf etc in the same EFI location at boot1.efi or similar. This would be worth addressing. > An older FreeBSD boot .img had been dd'd to another disk partition.

Ahh, yes. Sorry this tripped you up.
boot1.efi finds the first available UFS filesystem and loads loader.efi from there. You can skip boot1.efi altogether if you like, and just but loader.efi and the .4th and config files in your EFI system partition, but you'll then need to explicitly set currdev to load the kernel.
np, thank-you *so* much for writing this. I've been waiting 2 years to install FreeBSD on this laptop. I'll submit a doc patch with some more info from what I learned/uncovered, should this go to the handbook or the wiki?

On minnowboard max, I am trying FreeBSD-11.0-CURRENT-amd64-20140714-r268622-mini-memstick.img via microSD card and console o/p looks like this: >>> FreeBSD EFI boot block Loader path: /boot/loader.efi Consoles: EFI console Image base: 0x79bab000 EFI version: 2.40 EFI Firmware: EDK II (rev 1.00) FreeBSD/amd64 EFI loader, Revision 1.1 (root@grind.freebsd.org, Mon Jul 14 18:35:42 UTC 2014) Loading /boot/defaults/loader.conf /boot/kernel/kernel text=0xfb6e98 data=0x1296b0+0x4e96e0 syms=[0x8+0x140e38+0x8+0x15ba73] Hit [Enter] to boot immediately, or any other key for command prompt.

This looks like a separate issue. Closing this bug and opened a new one: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192324 (In reply to Dave Cottlehuber from comment #10) > np, thank-you *so* much for writing this.

Documenting it on https://wiki.freebsd.org/UEFI would be a good start, I think. >> An older FreeBSD boot .img had been dd'd to another disk partition. >> It turns out that UEFI code will pick up the first available image >> it recognises and boots from that, and not the loader.efi and >> loader.conf etc in the same EFI location at boot1.efi or similar. >> This would be worth addressing. > Ahh, yes.

I'm finding a similar issue, but loading boot1.efi just get me: >> FreeBSD EFI boot block Loader path: /boot/loader.efi panic: No bootable partition found I guess that's because my system doesn't have any UFS partition, because I have a freebsd-boot partition, and my root is on zfs. I tried to load.efi, but it says the kernel is wrong and drop me into a loader console that works very weird (characters get added, if I write "show", sometimes say "sh" not found, or inserts random characters "shkokw". I tried to copy loader.4th over there, but still nothing happens... even worse, it seems that after adding .4th not even the `set` command is being recognized. @pablo I'm successfully booting direct from ZFS, here's what I learned:
1. it must be a UEFI-enabled boot image (10.1 pre-releases are good)
2. zfs must have a dataset with mountpoint=/ and your usual /boot/* stuff in here. Note this is not actually where the kernel will be loaded from, but it's where I keep the master copy so it's safely versioned on zfs.
3. the zpool* must have property bootfs set to point to that dataset, for example my default bootfs is:
bootfs=zroot/ROOT/default
4. you must have a FAT-style EFI partition, with the kernel modules & all boot loader stuff in it. I am not exactly sure if there's a way to trim this down and have a smaller set. You *must* copy this across from within FreeBSD, I was unable to boot FreeBSD if I used either a linux system to transfer, or OSX -- the FAT 8.3 path mangling screwed things up.
I keep the master of /boot in ZFS but rsync it across to the EFI partition. My /boot/loader.conf is:
# cat /efi/boot/loader.conf
# master in zfs:/boot/loader.conf but
# actually loaded from /EFI FAT partition
# remember to keep settings mirrored
# mkdir -m 0700 /efi
# mount -f msdosfs /dev/diskid/DISK-Z1F21XGNp1 /efi
# rsync -harv /boot /efi/boot --exclude=\*.symbols --del --partial --inplace
kern.geom.label.disk_ident.enable="0"
kern.geom.label.gptid.enable="0"
kern.vty="vt"
zfs_load="YES"
vfs.root.mountfrom="zfs:zroot/ROOT/default"
my EFI partition is (directories only):

As this is still a mac there is apple cruft in here. Working on getting rid of that. This might be better discussed on one of the mailing lists BTW rather than in a resolved ticket ;-).
