You're not giving us much to go on here ... - Does your hardware have hotpluggable PCIe slots? - What was the last version of the kernel that did work? - What messages do you see in dmesg? - Can you run 'ps' and get the wchan for the modprobe process to see where it's hanging? -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours. We can't possibly take such a retrograde step." -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
