I'm running stock Debian on a QNAP-453B mini device, an Apollo Lake-based NAS. Two of the SATA ports are using the Intel SATA controller, and the other two are using an unidentified ASMedia SATA controller. 01:00.0 SATA controller [0106]: ASMedia Technology Inc. Device [1b21:0625] (rev ff) Sadly, the ASMedia fails to initialize on bootup, giving errors like: [ 4.553800] ahci 0000:01:00.0: failed to stop engine (-5) <snip> [ 19.553318] ahci 0000:01:00.0: failed to stop engine (-5) [ 19.554075] ahci 0000:01:00.0: AHCI ffff.ffff 32 slots 32 ports ? Gbps 0xffffffff impl unknown mode The Intel SATA controller works. However, when I pass the pci=noacpi parameter on the kernel command line, the ASMedia controller also works correctly. Is this an ACPI or firmware issue? Is there a better way to work around or fix it? dmesg, dsdt lspci and more details at: https://bugzilla.kernel.org/show_bug.cgi?id=196805 Thank you, -- Mourad DC -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
