Hello everybody,
I've been trying to make UEFI booting work on my Thinkpad T420. My goal is (as I had previously with BIOS) to boot freebsd from a USB flash drive with my laptop hard drive encrypted.
The T420 is able to boot using UEFI if FreeBSD is installed entirely on the HDD (ada0) or the USB flash drive (da0).
However, when I try to boot from USB and then access the ROOT partition on the HDD, I get the following panic:
Here are the commands I used (without encryption for the moment):
Create the EFI and /boot partition on the USB flash drive:
Prepare the EFI partition:
Partition the HDD. For this example, I will only use one big / partition.
Newfs and mount everything:
Install FreeBSD:
chroot into the new system and create /etc/fstab and /boot/loader.conf
Unmount everything and reboot
And I get a panic (as shown above)
Any idea on how to make this work with UEFI? From what I understood, EFI tries to boot on the first ufs partition found. It should be therefore da0p2 ... but it isn't.
Thank you very much.
