Hello everybody,
I am trying to put into operation a proprietary board using a freescale MPC8641D. I use U-boot 1.3.0 and Linux kernel 2.6.25-11.
On one PCIe-bus I have a PEX8518 followed by a PEX8114. A USB-controller is connected to the 8114.
+--------------------------+
| |
| MPC 8641 D |
| |
+--------------------------+
|
PEX8518 <----------------- PCIe switch
|
PEX8114 <----------------- PCIe to PCI bridge
|
ISP1562 <----------------- USB controller
The PCIe-components are scanned correctly, resources (mem and IO) are assigned (correctly as far as I understand),
but on the first read access to a control register of the usb-device the kernel generates "Oops: Machine check, sig: 7 [#1]".
Writing to the same register does not produce an "Oops".
The PCIe bus is defined in dts file as follows (dump from U-boot):
pcie@d4008000 {
cell-index = <0>;
compatible = "fsl,mpc8641-pcie";
device_type = "pci";
#interrupt-cells = <1>;
#size-cells = <2>;

and here the output from kernel:

Rebooting in 180 seconds..
where resource start = 0x80000000 is the physical address of the USB controller, base = 0xe1056000 is the virtual address.
Does anyone know this kind of problem and can give me a hint.
Kind Regards,
