Hello Rötti! Marek found a issue in that Asmedia SATA controller and sent patch which should workaround it: https://lore.kernel.org/linux-pci/20210317115924.31885-1-kabel@xxxxxxxxxx/T/#u Issue happen only with PCIe controllers which support 512 byte long packets. Seems that this SATA controller presents that is capable of 512 byte long packets, but when it is enabled then controller / system crashes. And based on our testing, it is rare to have machine with PCIe which support 512 byte long packets. None of our x86 Intel machine support it. So I guess you would not be able to reproduce this issue on your x86 device and probably also not on low-end ARM device too. You can check maximal size supported by PCIe controller by looking at line "DevCap: MaxPayload 512 bytes" in lspci output for device named "PCI bridge". My Intel based laptops have only "DevCap: MaxPayload 128 bytes". We have only two platforms (Marvell A3720 and CN9130) with 512 bytes, which are affected and patch for both of them fixes support for that Asmedia SATA controller. On Espressobin (A3720 based) that issue appeared in kernel version which introduced support for PCIe Root bridge which allows kernel to configure MaxPayload size and therefore enable usage of 512 bytes.
