Modified files: sys/dev/fdt : mvkpcie.c Log message: Allegedly a "Marvell Armada 3700 Functional Errata, Guidelines, and Restrictions" document exists that discusses an errata #251 in section "3.12 PCIe Completion Timeout" and suggests that setting the DIS_ORD_CHK flag in the Debug Mux Control register is necessary as a workaround: https://lore.kernel.org/linux-pci/20210624222621.4776-6-p...@kernel.org This workaround is still being discussed by the Linux developers, but it does fix an issue I am seeing with athn(4), where an external abort happens under load. So apply this workaround since its potential side effects seem to be significantly less severe than provoking an external abort that hangs the machine. ok patrick@
