Hi Again,I tried to find out the details for following errorata1: SATA link down (SStatus 4 SControl 300)As per status register descriptionSStatus 4 : Phy in offline mode as a result of the interface being disabled or running in a BIST loopback modeIs there any chance that coreboot/grub/Linux is putting SATA in to BIST loopback mode?I am trying to understand who is responsible for SATA Linux status 4 and possible candidates area) corebootb) grubc) LinuxLooking forward to your expert adviceThanksOn Fri, Mar 3, 2017 at 9:29 PM, Gailu Singh <gailu96@gmail.com> wrote:Hi Experts,I am trying to boot Linux 4.1 with coreboot and grub but SATA drive fails with error "ata1: SATA link down (SStatus 4 SControl 300)". It is interesting that GRUB2 can use the SATA drive without issue and able to load kernel from SATA disk.If I use same SATA Drive with Coreboot+UEFI payload then Linux driver just works fine and I am able to boot linux.Any Idea What might be going wrong with Linux Driver. Does it expect something from BIOS/Coreboot that is not fulfilledLinux boot logs:---------------------Initializing cgroup subsys cpusetInitializing cgroup subsys cpuInitializing cgroup subsys cpuacctLinux version 4.1.21-WR8.0.0.11_standard (vgahlaut@ubuntu) (gcc version 5.2.0 (Wind River Linux 5.2.0-8.0-intel-apollolake-i-64) ) #1 SMP PREEMPT Mon Feb 6 18:38:46 PST 2017 Command line: BOOT_IMAGE=(ahci0,msdos1)/boot/bzImage root=/dev/sda1 rootdelay=10 console=ttyS2,115200 KERNEL supported cpus:Intel GenuineIntelAMD AuthenticAMDCentaur CentaurHaulse820: BIOS-provided physical RAM map:BIOS-e820: [mem 0x0000000000000000-0x0000000000000fff] type 16 BIOS-e820: [mem 0x0000000000001000-0x000000000009ffff] usable BIOS-e820: [mem 0x00000000000a0000-0x00000000000fffff] reserved BIOS-e820: [mem 0x0000000000100000-0x000000000fffffff] usable BIOS-e820: [mem 0x0000000010000000-0x0000000012150fff] reserved BIOS-e820: [mem 0x0000000012151000-0x000000007a64ffff] usable BIOS-e820: [mem 0x000000007a650000-0x000000007affffff] type 16 BIOS-e820: [mem 0x000000007b000000-0x000000007fffffff] reserved BIOS-e820: [mem 0x00000000d0000000-0x00000000ffffffff] reserved BIOS-e820: [mem 0x0000000100000000-0x000000017fffffff] usable NX (Execute Disable) protection: activeSMBIOS 2.7 present.e820: last_pfn = 0x180000 max_arch_pfn = 0x400000000PAT configuration [0-7]: WB WC UC- UC WB WC UC- UCe820: last_pfn = 0x7a650 max_arch_pfn = 0x400000000Scanning 1 areas for low memory corruptionUsing GB pages for direct mappinginit_memory_mapping: [mem 0x00000000-0x000fffff]init_memory_mapping: [mem 0x17fe00000-0x17fffffff]init_memory_mapping: [mem 0x160000000-0x17fdfffff]init_memory_mapping: [mem 0x00100000-0x0fffffff]init_memory_mapping: [mem 0x12151000-0x7a64ffff]init_memory_mapping: [mem 0x100000000-0x15fffffff]ACPI: Early table checksum verification disabledACPI: RSDP 0x00000000000F0000 000024 (v02 CORE )ACPI: XSDT 0x000000007A6690E0 00005C (v01 CORE COREBOOT 00000000 CORE 00000000)ACPI: FACP 0x000000007A66BA60 00010C (v05 CORE COREBOOT 00000000 CORE 00000001)ACPI BIOS Warning (bug): 32/64X length mismatch in FADT/Pm1aEventBlock: 32/16 (20150410/tbfadt-623)ACPI BIOS Warning (bug): Invalid length for FADT/Pm1aEventBlock: 16, using default 32 (20150410/tbfadt-704)ACPI: DSDT 0x000000007A669280 0027D8 (v05 COREv4 COREBOOT 20110725 INTL 20160831)ACPI: FACS 0x000000007A669240 000040ACPI: FACS 0x000000007A669240 000040ACPI: SSDT 0x000000007A66BB70 000774 (v02 CORE COREBOOT 0000002A CORE 0000002A)ACPI: MCFG 0x000000007A66C2F0 00003C (v01 CORE COREBOOT 00000000 CORE 00000000)ACPI: TCPA 0x000000007A66C330 000032 (v02 CORE COREBOOT 00000000 CORE 00000000)ACPI: TPM2 0x000000007A66C370 000034 (v04 CORE COREBOOT 00000000 CORE 00000000)ACPI: APIC 0x000000007A66C3B0 00006C (v01 CORE COREBOOT 00000000 CORE 00000000)ACPI: HPET 0x000000007A66C420 000038 (v01 CORE COREBOOT 00000000 CORE 00000000)Zone ranges:DMA [mem 0x0000000000001000-0x0000000000ffffff] DMA32 [mem 0x0000000001000000-0x00000000ffffffff] Normal [mem 0x0000000100000000-0x000000017fffffff] Movable zone start for each nodeEarly memory node rangesnode 0: [mem 0x0000000000001000-0x000000000009ffff] node 0: [mem 0x0000000000100000-0x000000000fffffff] node 0: [mem 0x0000000012151000-0x000000007a64ffff] node 0: [mem 0x0000000100000000-0x000000017fffffff] Initmem setup node 0 [mem 0x0000000000001000-0x000000017fffffff] ACPI: PM-Timer IO Port: 0x408IOAPIC[0]: apic_id 2, version 32, address 0xfec00000, GSI 0-119ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 2 dfl dfl)ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 low level)Using ACPI (MADT) for SMP configuration informationACPI: HPET id: 0x8086a701 base: 0xfed00000smpboot: Allowing 4 CPUs, 0 hotplug CPUsPM: Registered nosave memory: [mem 0x00000000-0x00000fff]PM: Registered nosave memory: [mem 0x000a0000-0x000fffff]PM: Registered nosave memory: [mem 0x10000000-0x12150fff]PM: Registered nosave memory: [mem 0x7a650000-0x7affffff]PM: Registered nosave memory: [mem 0x7b000000-0x7fffffff]PM: Registered nosave memory: [mem 0x80000000-0xcfffffff]PM: Registered nosave memory: [mem 0xd0000000-0xffffffff]e820: [mem 0x80000000-0xcfffffff] available for PCI devicesclocksource refined-jiffies: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 1910969940391419 nssetup_percpu: NR_CPUS:4 nr_cpumask_bits:4 nr_cpu_ids:4 nr_node_ids:1PERCPU: Embedded 32 pages/cpu @ffff88017fc00000 s93912 r8192 d28968 u524288Built 1 zonelists in Zone order, mobility grouping on.
