Bug ID: 14281
Summary: Boot process stuck at "GRUB loading.." since 2021.02.1
Product: buildroot
Version: 2021.02.5
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned@buildroot.uclibc.org
Reporter: stefan.walter@iml.fraunhofer.de
CC: buildroot@uclibc.org
Target Milestone: ---
The following used to work until including Buildroot 2021.02, i.e. the
resulting image used to boot normally. Ever since Buildroot 2021.02.1, the
resulting image does not boot any more - the boot process either gets stuck
right after displaying "GRUB loading..", or it reboots at that point, leading
to an infinite boot loop. More specifically, this problem exists since the
following commit:
e840f2d469 boot/grub2: Backport 2021/03/02 securify fixes
Here's what I'm doing:
1. Run Buildroot to create a root partition image (my_defconfig attached).
2. Create a GRUB image like this (grub_early.cfg attached):
/path/to/buildroot-sdk/host/bin/grub-mkimage --config=grub_early.cfg
--directory=/path/to/buildroot-sdk/host/lib/grub/i386-pc -o
./genimage_input_tmp/grub_core.img --format=i386-pc --prefix==/boot/grub
biosdisk part_msdos ext2 normal linux configfile
3. Create a home partition image like this:
MKE2FS_CONFIG=/path/to/buildroot-sdk/host/etc/mke2fs.conf
/path/to/buildroot-sdk/host/sbin/mke2fs -d home_partition_prep/home -j -L home
-t ext3 -U random -b 4096 ./genimage_input_tmp/home.ext3 25M
4. Create a disk image like this (genimage.cfg attached):
/path/to/buildroot-sdk/host/bin/genimage --loglevel=1 --config=genimage.cfg
--inputpath=./genimage_input_tmp --outputpath=images
--rootpath=home_partition_prep --tmppath=./genimage_tmp
--tune2fs=/path/to/buildroot-sdk/host/usr/sbin/tune2fs
--e2fsck=/path/to/buildroot-sdk/host/usr/sbin/e2fsck
(Note that I had also previously raised this issue on the Buildroot mailing
list - see
http://lists.busybox.net/pipermail/buildroot/2021-October/625323.html.)

--- Comment #4 from Thomas Petazzoni <thomas.petazzoni@bootlin.com> ---
When you say "The following used to work until including Buildroot 2021.02",
could you clarify which version of Buildroot works for you ? 2020.11 is working
?
If so, could you take 2021.02, and try to downgrade the version of gcc and/or
binutils ? Buildroot offers the choice of 3 versions for gcc and binutils: X-1,
X and X+1, where X is the default. Could you try to use X-1 for gcc, and X-1
for binutils, and see if it improves the situation ?

No problem:
- Version 2020.02.11 works
- Version 2021.02 works
- Version 2021.02.1 does not work
I could try using other GCC versions, and had actually already started doing
that, but the hint given at
http://lists.busybox.net/pipermail/buildroot/2021-October/626296.html revealed
that using the GRUB image in build/grub2-2.04/grub-core instead of the one in
host/lib/grub/i386-pc helps. I can confirm that I get a booting image with
that.
So, as mentioned by Peter in that e-mail, it looks like a problem with
host-grub2...?

I'll attach the patch that Peter sent in
http://lists.busybox.net/pipermail/buildroot/2021-October/626342.html to this
issue for the sake of completeness. I can confirm that, with the patch applied
to the head of the 2021.02.x branch (241a7c6fe7 in my case), I get a booting
image again. It would be great to have this in 2021.02.7.
