Subject: [PATCH] ata: ahci: Add AMD 600 Series Chipset SATA Controller (0x43f6)
Date: Tue, 10 Mar 2026 15:49:56 +0000	[thread overview]
Message-ID: <20260310154956.743071-1-linuxoid@gmail.com> (raw)

Add PCI ID 0x43f6 for the AMD 600 Series Chipset (B850/X870) SATA
controller to ahci_pci_tbl. Without this entry, the AHCI driver does
not bind to the controller and SATA devices are invisible at boot.

Users can work around the issue with:
  echo "1022 43f6" > /sys/bus/pci/drivers/ahci/new_id

Closes: https://bugzilla.kernel.org/show_bug.cgi?id=221193
