The ASMedia ASM1062 SATA controller causes an External Abort on
controllers which support Max Payload Size >= 512. It happens with
Aardvark PCIe controller (tested on Turris MOX) and also with DesignWare
controller (armada8k, tested on CN9130-CRB):
ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
ata1.00: ATA-9: WDC WD40EFRX-68WT0N0, 80.00A80, max UDMA/133
ata1.00: 7814037168 sectors, multi 0: LBA48 NCQ (depth 32), AA
ERROR: Unhandled External Abort received on 0x80000000 at EL3!
ERROR: exception reason=1 syndrome=0x92000210
PANIC at PC : 0x00000000040273bc
Limiting Max Payload Size to 256 bytes solves this problem.
On Turris MOX this problem first appeared when the pci-aardvark
controller started using the pci-emul-bridge API, in commit 8a3ebd8de328
("PCI: aardvark: Implement emulated root PCI bridge config space").
On armada8k this was always a problem because it has HW root bridge.
