--- Comment #45 from ek@purplehat.org ---
Same issue here on a HPE DL380 G9. Totally headless. 14.3 installer works fine,
but the 15.0-RELEASE installer hangs and then reboots after about 5 seconds
after the:

staging 0x61800000 (not copying) tramp 0x6170b000 PT4 0x61702000
Start @ 0xffffffff8032ae40 ...
EFI framebuffer information:
addr, size     0x80000000, 0x300000
dimensions     1024 x 768
stride         1024
masks          0x00ff0000, 0x0000ff00, 0x000000ff, 0xff000000

I've tried all the suggestions that I've found here but nothing has worked.

FreeBSD 14.3-RELEASE installer works fine. Even the pkgbase upgrade to
15.0-RELEASE works fine. I thought the problem was solved after that, but once
I update the zroot EFI bootcode, I ran into the exact same problem. Not sure
where to go from here. I could reinstall 14.3 and then update to 15.0 again
using pkgbase (freebsd-update fails with a libc.so.7 issue), but I would need
to leave the ZFS zroot pool on the old bootcode, I guess.

I haven't tested this with UFS. Is this still being worked on or is it already
fixed? Maybe I'm missing something? It's such a strange issue to have on a
headless server.
