I have used kernel 2.4.18 for a year or so on my current machine and now I am also using 2.6.8-1-686 on the same machine. I can specify the modules I want loaded at boot time in /etc/modules so should I put modules for both 2.4 and 2.6 kernels in there? In particular, the module usb-uhci.o for 2.4 has become uhci-hcd.ko for 2.6 (I think). Should both usb-uhci and uhci-hcd appear in /etc/modules? Barrie.
