--- Comment #8 from [email protected] ([email protected]) --- Yes — system is already running the latest BIOS / UEFI firmware available from the vendor. BIOS was also reset to defaults to rule out configuration-side issues. The behavior is the same with: - Default BIOS settings - Reset NVRAM - CSM disabled - Secure Boot on and off Additionally, the issue is reproducible across multiple kernel versions (6.6 LTS, 6.8, and 6.18-rc builds), and occurs regardless of kernel command-line parameters unless ACPI is fully disabled (`acpi=off`), which suggests the hang occurs during early ACPI/APIC initialization before PCI/USB/NVMe enumeration. This points to an ACPI or IOMMU initialization path that is failing silently rather than a firmware misconfiguration. If helpful, I can provide: - Full `dmesg` boot log (normal vs `acpi=off`) - `acpidump` table set - `journalctl -b -1` traces (from successful acpi=off boot) Just let me know which format you prefer.

Tashkinov ([email protected]) --- Are you using the latest BIOS? If not, please update. Also would be great if you reset BIOS settings. -- You may reply to this email to add a comment.
