No, I didn't. I am netbooting, so I wouldn't have noticed... Don't think I've tried booting any Debian kernels from an SD card yet. Will try to find some time to test it. But I find using SD cards more quite a hassle :-) > Was it fixed by enabling > CONFIG_PCIE_BRCMSTB, or is that a different issue? Probably different. I believe this driver just enables the PCIe controller, which should be independent of anything else except the PCIe connected xhci controller. Bjørn
