> Hardware:
> - MSI MAG Z790 TOMAHAWK WIFI (MS-7D91), Intel i9-14900KF
> - Chipset: Intel Raptor Lake (Z790)
> - Storage: Samsung SSD 860 EVO (SATA), Corsair MP600 NVMe
> - GPU: NVIDIA RTX 4070 Ti
> 
> Issue:
> - Booting 6.16.8+kali-amd64 fails with:
>     ahci: failed to start port (errno=-12)
>     xhci_hcd 0000:00:14.0: init failed, error -12
> - System drops into initramfs, USB keyboard not functional at that point.
> - GRUB works (disk visible to firmware).
> - Booting older kernel 6.12.38+kali-amd64 works fine on same hardware.
> 
> Additional:
> - Also see:
>     platform INT3515:01: deferred probe pending: Error creating i2c-client,
> idx 0
> - This message appears on both kernels, but is not fatal on 6.12.
> 
> Steps to reproduce:
> 1. Boot system with kernel 6.16.8.
> 2. Observe ahci/xhci errors and initramfs hang.
> 3. Reboot and select 6.12.38 → boots normally.
> 
> Conclusion:
> Regression between 6.12 and 6.16 affecting Intel Raptor Lake SATA AHCI and
> USB XHCI controllers.

Is your BIOS set to Intel RST or AHCI mode?
