Willian Barsse wrote
"There seems to be a slight problem with the "mod_strcmp" function in modprobe.c, it scans for the first occurence of the module name in the "mod_path" variable and expects it to be the last path element. ie /lib/modules/2.4.22-debug/kernel/fs/vfat in my example. The comparison will always fail if mod_path contains another substring matching the module name." Robert McQueen wrote "Although William Barsse's patch fixed mod_strcmp for 2.4 kernels, there was a remaining problem which prevented it from working for me. I've just tracked it down - when you enable kernel 2.6 module support it hard-wired the extension to .ko instead of checking at runtime like the other places where 2.4 differs from 2.6. The attached patch fixes this for me."
