Does it find the storage controller (what kind of > storage does it use?). It seems not. I don't see any infos about hard disks in the kernel ring buffer. The two serial ATA (SATA 2.0) controllers are integrated in the P5020 SoC and the hard disks are connected via SerDes lanes (PCIe) to the SoC. LANE 16 = SATA 0 and LANE 17 = SATA 1. > For the PASEMI board can you test the attached patch? Also are you > using Compact Flash cards on that system? Yes, we are using Compact Flash cards. The slot is wired to the CPU local bus. It works with your kernel. :-) Where is the attached patch? I downloaded the version 5 of your Git kernel and compiled it today. Unfortunately the PASEMI ethernet doesn't work. Error message: pci 0000:00:1a.0: dma_direct_map_page: overflow 0x000000026bcb5002+110 of device mask ffffffff bus mask 0 @All Could you please also test Christoph's kernel on your PASEMI and NXP boards?
