--- Comment #11 from [email protected] ([email protected]) --- Thanks, Mario. Confirmed: booting with no parameters on 6.18-rc4 hangs consistently at “Loading initial ramdisk…” when ACPI is enabled. The hang occurs before a usable tty appears, so I’m not able to obtain dmesg in that state. Booting with `nomodeset` (without disabling ACPI) also hangs at the same point. No output progresses past the initramfs handoff. The only configuration that currently boots to a stable userspace environment is: acpi=off pci=noacpi nomodeset which I understand is not viable long-term or appropriate for debugging. To proceed with your request, I will capture: • dmesg from a boot using: `loglevel=8 acpi.debug_layer=0x2 acpi.debug_level=0x4` • and a raw ACPI table dump via UEFI shell (`acpidump`), so you can inspect the DSDT/EC region directly. I’ll attach both artifacts shortly. .

There are just too many areas that rely upon ACPI. With 6.18-rc4, can you please provide the dmesg with no additional parameters added? Or are you saying that hangs? If that hangs can you please provide the output of dmesg with just nomodeset? -- You may reply to this email to add a comment. You are receiving this mail because: You are on the CC list for the bug.
