--- Comment #10 from [email protected] ([email protected]) --- Thanks for the guidance, Artem. BIOS version is current (F.22, 2024-09 release), and the BIOS settings have now been reset to defaults before testing. I have tested both recommended ACPI OSI override variants: 1) acpi_osi=! acpi_osi="Windows 2022" 2) acpi_osi=! acpi_osi="Windows 2015" Unfortunately, neither configuration allows the system to proceed past "Loading initial ramdisk" — same behavior as with no flags. Regarding acpidump: The system freezes when ACPI is enabled, so I cannot collect acpidump directly in a normal boot. I *can* run acpidump when booting with `acpi=off`, and I can also use the UEFI shell method (acpidump.efi). Please confirm whether a dump generated in `acpi=off` mode is still useful, or if the UEFI shell dump is preferred. I am prepared to provide whichever format is needed. For the debug log request: I will capture output using: loglevel=8 acpi.debug_layer=0x2 acpi.debug_level=0x4 and will attach /var/log/dmesg (or serial console capture) on next reboot attempt without any additional boot parameters. Expected attachments next: - acpidump output (UEFI shell if preferred) - full dmesg log with debug flags enabled Sent from Proton Mail for Android. -------- Original Message -------- On Wednesday, 11/05/25 at 00:48 [email protected] wrote: https://bugzilla.kernel.org/show_bug.cgi?id=220749 Artem S.
