[issue]: FreeBSD 14.x not working workaround included..

[jsm222]

Official FAQ

• I have checked the official FAQ.

Ventoy Version

1.0.96

What about latest release

Yes. I have tried the latest release, but the bug still exist.

Try alternative boot mode

Yes. I have tried them, but the bug still exist.

BIOS Mode

UEFI Mode

Partition Style

GPT

Disk Capacity

8GB

Disk Manufacturer

bhyve

Image file checksum (if applicable)

None

Image file download link (if applicable)

No response

What happened?

Note to workaround this I builded geom_ventoy.ko from 13.x sources on 14.0-RC2 and placed it in
ventoy/ventoy_unix.cpio xz compressed. So it seems the shipped 14.x kmod is wrong or outdated..

Thanks

I confirm. I tried to boot FreeBSD 14 RC3 but i get some errors then the system reboots. I can't read the errors because they appear for just a second, but it seems the same reported above

How to correctly build this? Something like this? Is it documented somewhere?

wget https://download.freebsd.org/releases/amd64/14.0-RC4/src.txz # NOTE: Change accordingly
sudo tar xz src.txz  -C /
git clone https://github.com/ventoy/Ventoy/
cd ./Ventoy/Unix/ventoy_unix_src/FreeBSD/geom_ventoy_src/13.x/sys/modules/geom/geom_ventoy
mkdir -p geom/ventoy
cp ../../../geom/ventoy/* geom/ventoy
cp ../../../geom/ventoy/* .
export CC=$(which clang)
make
xz geom_ventoy.ko

I'm a FreeBSD Ventoy user. What is the nature of the problem?
What is geom_ventoy.ko used for?

[derekschrock]

With 14.0-RELEASE now out this should be a real issue.

On a 13.2 host with release/14.0 branch src worked rebuilding geom_ventoy.ko and in turn ventoy_unix.cpio

[Alex6357]

14.0-RELEASE still not supported

[grahamperrin]

FreeBSD 14.0 and beyond

From report 275326 – 14.0-RELEASE dvd1-iso installer used in Ventoy got boot panic, comment 6:

I am very interested in improving Ventoy support in FreeBSD, but that will only apply to future releases. This is not a FreeBSD bug and there is nothing we can do for 14.0 - Ventoy needs to be updated to be compatible.

(Cross-reference at comment 7.)

I'll hide my previous comment as outdated.

git clone https://github.com/ventoy/Ventoy/
cd ./Ventoy/Unix/ventoy_unix_src/FreeBSD/geom_ventoy_src
cp -a 13.x 14.x
cd 14.x/sys/modules/geom/geom_ventoy
mkdir -p geom/ventoy
cp ../../../geom/ventoy/* geom/ventoy
cp ../../../geom/ventoy/* .
export CC=$(which clang)
make
xz geom_ventoy.ko

I can verify the above steps worked on my FreeBSD 14.0Release system. I had the FreeBSD source code loaded into the standard location (i.e. /usr/src). Note my system is x86_64. I'm not sure how to build the 32-bit version...

Then one must put the geom_ventoy.ko.xz (produced above) into the ventoy_unix.cpio file (this file is in the VTOYEFI partition in the ventoy folder -- I copied it to my FreeBSD box and did the following):
$ cpio -it < ventoy_unix.cpio
$ cp geom_ventoy.ko.xz ventoy_unix/FreeBSD/geom_ventoy_ko/14.x/64/
$ mv ventoy_unix.cpio orig_ventoy_unix.cpio # if you want to save the original :-)
$ find ventoy_unix | cpio -o >ventoy_unix.cpio

Then copy your newly created ventoy_unix.cpio to the ventoy folder on the VTOYEFI partition of your thumb drive.

I put a copy of the geom_ventoy.ko that I built for testing in https://people.freebsd.org/~emaste/Ventoy/

Thank you, you are all excellent people! Wanted to report that using Ed's ventoy_unix.cpio in the VTOYEFI partition's ventoy folder got FreeBSD-14.0-RELEASE-amd64-dvd1.iso to boot for me!

[Alex6357]

My guess: FreeBSD changed MAXCPU in GENERIC build recently, which made all third-party kernel modules broken and needed to be rebuilt. That explains why early stage snapshots of 14.0 works but 14.0-RELEASE doesn't.

[bkw777]

1.0.97 claims to support fbsd 14.0 but 1.0.97 and FreeBSD-14.0-RELEASE-amd64-dvd1.iso just reboots on my Sony SVZ1311.
So does the bootonly.iso and so does Ghostbsd 24.0.1.1, both normal and xfce versions.
After selecting "boot normally" it does show some sort of bootloader message for a split-second. It's not the boot.4th menu, just 3 or 4 short lines only a couple words each.
14.0 installs and runs fine from the same thumb drive (dd memstick.img, sandisk extreme pro 256g) on the same machine.

Close this issue?

• Updated FreeBSD modules for 14.0Release. #2679
• https://github.com/ventoy/Ventoy/releases/tag/v1.0.97

[grahamperrin]

#2636 (comment)

… bootloader message for a split-second. …

A different symptom, probably a different issue.

@bkw777 have you raised the issue elsewhere, in a FreeBSD area?

[bkw777]

FreeBSD area?
The freebsd image booted fine directly without ventoy. As in dd the image right to the thumb drive.
I haven't tried any newer versions of either ventoy or freebsd on that machine since then though.
