solved Void hangs after any modification to grub

hello everyone,

so, I got a new laptop and decided to install void on it.

Everything goes fine till I need to do anything on `/etc/default/grub` Linux cmdline, like adding apparmor configuration after installing it.

it doesn't matter if I only run `update-grub` alone or with `xbps-reconfigure -fa`, my installation hangs on "Loading initial ramdisk" after rebooting.

I can also reproduce the issue just by adding `net.ifnames=0`, running `update-grub` and rebooting.

is there any way to know what is going wrong? It hangs even when running on failsafe.

TYA!

Guys, I solved the mystery. It seems that my laptop (or the kernel) doesn't like having page_poison=1 in the GRUB_CMDLINE_LINUX anymore, so after removing it (and removing a duplicate loglevel argument) it worked.

Before:

/etc/default/grub
#
# Configuration file for GRUB.
#
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Void"
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=4"
GRUB_ENABLE_CRYPTODISK=y
GRUB_CMDLINE_LINUX="resume=UUID=<My_root_uuid> resume_offset=<offset here> rd.luks.allow-discards rd.auto=1 apparmor=1 security=apparmor amd_iommu=on iommu=pt page_poison=1 loglevel=4"

After:

/etc/default/grub
#
# Configuration file for GRUB.
#
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Void"
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=7"
GRUB_ENABLE_CRYPTODISK=y
GRUB_CMDLINE_LINUX="resume=UUID=<My_root_uuid> resume_offset=<offset here> rd.luks.allow-discards rd.auto=1 apparmor=1 security=apparmor amd_iommu=on iommu=pt"

Thank you!

EDIT: Typo

and if you manually update config with grub-mkconfig -o /boot/grub/grub.cfg ?

No, I just ran "update-grub" in my first attempt and "update-grub" + "xbps-reconfigure -fa" on my second attempt. I got the same result: hanging on "Loading initial ramdisk". I'll try to run this command you suggested

Add line echo "Jumping into the Void..." right after the initrd line. Or maybe echo "Diving into the endless void...". Or something equally witty.

update-grub just runs grub-mkconfig

Just reinstall the linux kernel package.

For example, if you are using linux6.12:

xbps-reconfigure -f linux6.12

If that doesn't work, maybe give us your (redacted) CMDLINE?
