Created attachment 265372 [details] dmesg November 6th snapshot was tested. No matter what options I select I cannot get FreeBSD 15.0 to boot from an SN850X NVMe stick, this worked fine in 14.3, and is also fine in Linux. It does work if efiboot is manually run following install. Unlike 14.3 the install very rarely, if ever, pops up a note about clearing UEFI boot entries so I suspect it's not running at all. Targeted configuration is UEFI boot, ZFS on root, 64GB swap partition. UK keyboard layout. New package test (although tried old, no different).
Created attachment 265373 [details] output of efibootmgr -v output of efibootmgr -v run against install media. It's the same both before and after the installation. The installation does work to put files on the drive - it just doesn't boot.
Workaround : exit loader to loader prompt load /boot/kernel/kernel load /boot/kernel/zfs.ko set currdev="zfs:zroot/ROOT/default:" boot to boot from new installation via install media, then. efibootmgr -a -c -l /boot/efi/EFI/freebsd/loader.efi -L FreeBSD-15 from install. It then works fine.
