Just upgraded my Asus UX303L (amd64) from 11-STABLE to 12.0-BETA1 r339529
by source. Have a problem with booting which hangs after:
>> FreeBSD EFI boot block
Loader path: /boot/loader.efi
Initializing modules: ZFS UFS
Probing 5 block devices ... done
ZFS found the following pools: zroot
UFS found no partitions
Consoles: EFI console
FreeBSD/amd64 EFI loader, Revision 1.1
Command line arguments: loader.efi
EFI version 2.31
EFI Firmware: American Megatrends (rev 4.654)
Console: efi(0)
Load Path: HD(4, GPT [ ... ]
Load Device: Pci Root [ ... ]
Boot Current: 0001
Boot Order: 0001 [x]
Boot Info Path: HS(1, GPT, [ ... ] /\EFI\BOOT\BOOTX64.EFI
-
So it gets into loader.efi which runs but stops I think just before loading
the kernel. Partitions:
=> 40 250069600 ada0 GPT (119G)
40 1600 1 efi (800K)
1640 1024 2 freebsd-boot (512K)
2664 1432 - free - (716K)
4096 4194304 3 freebsd-swap (2.0G)
4198400 245870592 4 freebsd-zfs (117G)
250068992 648 - free - (324K)
and the EFI partition is FAT 12.
I can't provide (at the moment) any output from efibootmgr:
root@gryphon:~ # efibootmgr -v
efibootmgr: efi variables not supported on this system. root? kldload efirt?
root@gryphon:~ # kldload efirt
kldload: can't load efirt: module already loaded or in kernel
which I don't understand.
I'm going to rebuild the kernel (currently GENERIC) and see if that allows
me to load efirt / use efibootmgr.
In the meantime, I should be very grateful for any advice.
( Currently booting using a 11-RELEASE memstick image and dropping into its
loader to get to the installed 12-STABLE ).
