The HW in question is an AMD 3900X and ASRock Taichi B550 MB. I have turned both CPU and MB in for warranty and the defect remains. What happens is this: 1: I get my ASM1166 6 port SATA PCIe 2.0 expansion card and plug it into the second 16 lane wide PCIe port (my GPU is in the top one). It is connected to the CPU's PCIe lanes. 2: I try to boot. I get several errors regarding memory and chipset initialization errors. In particular. The last is error code 94. The system fails to POST and reboots. 3: I place the AIC into the lowest PCIe port (also 16 lanes wide), and the system boots without a problem. The AIC works correctly. The AIC is then electrically connected to the chipset, not the CPU. I'm attaching the output of lspci for the AIC. Here's the AIC I purchased: https://www.ebay.com/itm/PCIE-SATA-3-0-PCI-E-SATA-Card-PCI-E-PCI-Express-SATA-Controller-6-Ports-SATA3-X4/114295190520 IMHO, the problem could be: The Chipset, because it doesn't initialize. The CPU, because it's PCIe lanes go as far as the second PCIe 16 lane port). The PCIe 4.0 re-drivers, because they might be malfunctioning. The card, because it might abuse the PCIe 2.0 protocol. So, who should I report this to? AMD or ASRock? Is there anything I can do to further isolate this problem? Is what I have written sufficient, or would you recommend that I add some other info? Is there any difficulty to trying to file a report with AMD and ASRock which you would have any suggestions about working around?
