Hrmph. There was a 32-bit issue in 0.9.0-1 that was supposed to be fixed
in 0.9.0-2:

Any chance you can test with efibootmgr from unstable? I've looked at
the changes upstream and don't see anything that seems like it'd be
relevant to "efibootmgr -v" segfaulting. However, about "efibootmgr -c
-d /dev/sda -o 1 -w -L debian -l \EFI\debian\grubia32.efi" failing,
these changes are in unstable's efibootmgr and might be relevant:
8c725c629f2ead41532c4b908e9c713187a7f564 - Make -o's behavior actually
match the documented behavior.
b857ce058d6f7fa3fa47c839bc86de243cd1fd4e - Make all the other places
we're parsing XXXX also do a better job.
Once you test against unstable's efibootmgr, Peter Jones (upstream) can
help us try to triage this bug more.
Relatedly, there are a bunch of fixes since 0.9.0-2. Actually, all
changes since then are bug fixes. How hard would it be at this point in
the game to get an exception to pull 0.11.0 into testing?

Hi Jared,
Testing on an i386 EFI installation using OVMF in qemu, efibootmgr
just doesn't work properly. I'm working on i386 UEFI support in d-i,
so I've built an i386 UEFI installer image. During installation,
everything completes without error, but the system didn't boot after
reboot.
Booting the system by hand, I can run efibootmgr by hand and I get
(transcribed by hand, so may have the odd error):
root@debian:~# efibootmgr
BootCurrent: 0000
BootOrder: 0002,0003,0004,0000,0000
Boot0000: I DVD/CDROM
Boot0001: I Floppy
Boot0002: I Floppy 1
Boot0003: I Hard Drive
Boot0004: I Internal Shell
which tells me that the efibootmgr from "grub install" did not
work. Worse, "efibootmgr -v" crashes:
root@debian:~# efibootmgr -v
BootCurrent: 0000
BootOrder: 0002,0003,0004,0000,0000
Segmentation fault (core dumped)
I've attached the core dump for reference.
If I run grub-install by hand, I get more useful output:
root@debian:~# grub-install
Installing for i386-efi platform.
Could not prepare boot variable: No such file or directory
Installation finished. No error reported.
(Useful - clear failure, but grub-install reports no error!)
"grub-install -v" shows me the exact efibootmgr command that fails,
which is:
# efibootmgr -c -d /dev/sda -o 1 -w -L debian -l \EFI\debian\grubia32.efi
As expected, running that by hand gives the same error.
If I install an old version of efibootmgr for i386 (0.5.4-2), this all
works just fine. I can install a boot record for debian using "grub
install" or the "efibootmgr -c" command as above, and it
works. "efibootmgr" and "efibootmgr -v" both work
correctly. Tellingly, once I've used the older efibootmgr to install a
debian boot record, if I upgrade to 0.9.0-2 again and run "efibootmgr"
I now get a badly broken list:
root@debian:~# efibootmgr
BootCurrent: 0000
BootOrder: 0001,0002,0003,0004,0000,0000
Boot0000: I DVD/CDROM
Boot0001: I Floppy
Boot0002: I Floppy 1
Boot0003: I Hard Drive
Boot0004: I Internal Shell
Boot0005: bian
This smells like libefivar is broken on i386, maybe? Actually, not
sure. I've attached a gdb and the backtrace looks like:
(gdb) bt
#0 0x0805036c in unparse_raw_text (buffer=0x0, buffer_size=0, p=0x80570fc "",
length=4294967260) ar src/lib/unparse_path.c:69
#1 0x0804acb2 in show_boot_vars () at src/efibootmgr/efibootmgr.c:776
#2 0x0804bcec in main (argc=2, argv=0xbffffd74) at
src/efibootmgr/efibootmgr.c:1272
The length passed into unparse_raw_text() looks a little suspicious
(0xFFFFFFDC, or -36). Debugging further up in show_boot_vars:
boot->data_size is 64
load_option->file_path_list_length is 70
((char *)path - (char *)load_option) is 30
This looks a little wrong to me, but I've not dug any deeper.
