Thanks for your report. I opened this bug report: https://bugzilla.kernel.org/show_bug.cgi?id=110851 Can you please attach the complete dmesg logs from the old machine running 3.0.76 and the new machine running 3.0.76 to that bugzilla? Also please attach the complete "lspci -vvv" output for all the devices in the new machine. Is there any chance you can try a current kernel, e.g., v4.4, on the new machine? Even if you can't install a new kernel permanently, the dmesg log of PCI enumeration is enough to show whether we detect the Kodicom devices or not.
