--- Comment #21 from [email protected] ([email protected]) --- Update: I tested a direct kernel EFI stub boot to remove GRUB from the equation. Booted using: vmlinuz-6.18.0-rc3 with initrd.img-6.18.0-rc3 via an efibootmgr-created EFI entry (no bootloader involved). Result: The system freezes before any visible console output. Screen goes black immediately and keyboard power drops as soon as the firmware attempts to start the kernel. There is no kernel early printk output at all. This indicates the hang is occurring during the EFI → kernel handoff, before the kernel logging is initialized. So the issue appears to be in the firmware/ACPI transition path rather than GRUB or userspace. UART adapter is on the way; I will capture early printk UART trace next and share it here. -- You may reply to this email to add a comment.
