It would seem that the place to start looking in the PCIe device discovery code. I have obviously on tested this on virtual machine, but it could be that similar issue occur on physical machine (depending on quality of equation). Cheers, John Hartley. --=20 You are receiving this mail because: You are the assignee for the bug.=
