 Posted: Tue Apr 02, 2024 9:36 am Post subject: Grub freezes when trying to boot kernel |
 |
|
There was a recent version bump to Grub which I installed in mid march, and I have done:
| Code: | # sudo grub-install --efi-directory=/boot --bootloader-id=GRUB
Installing for x86_64-efi platform.
Installation finished. No error reported.
# sudo grub-install --efi-directory=/boot --bootloader-id=GRUB --removable
Installing for x86_64-efi platform.
Installation finished. No error reported.
# grub-mkconfig -o /boot/grub/grub.cfg
Generating grub configuration file ...
Found linux image: /boot/kernel-6.6.21-gentoo
Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.
Adding boot menu entry for UEFI Firmware Settings ...
done |
That all looks fine, and on rebooting I get the expected grub menu.
However, trying to boot, the screen clears, the same menu reloads, and the machine freezes completely, and needs to be power-cycled to become responsive again.
I can get in to the system with a usb-stick and
| Code: | set root=(hd4,gpt2)
linux /kernel-6.6.21-gentoo root=/dev/sdd4
boot |
So everything "post-grub" works fine, and I'm trying this message from the same system, but obviously I'd like to not depend on a separate grub to boot.
I have no idea how to "debug" grub as there's no error message, and of course no logs written to disc as no disc is mounted at this point.
Help?
Edit: I realized I should try the manual boot from the hosed grub as well:
grub> set root=(hd4,gpt2)
grub> linux /kernel-6.6.21-gentoo root=/dev/sdd4
grub> boot
error: start_image() returned 0x8000000000000005.
grub> _
So that's an error message of some kind at least. The number of zeroes in the return value may be wrong, as I can't copy-paste from grub and it's been manually typed. |

When running a regular update, nvidia-drivers complained that the current compiler was GCC 13, but the kernel was compiled with GCC 12.
It had nothing to do with my grub issue, but I figured it wouldn't hurt to fix. So kernel 6.6.21 got recompiled with GCC 13, but that didn't make a difference.
I also tried poking around in grub but I guess my C is a bit rusty, as I couldn't find the start_image implementation, nor the error code returned.
Maybe the start_image function comes from an external library? |
