I need to compile a hpfs module for FC2. I tried the method outlined for adding a NTFS module to FC1, but I get a lot of errors. I compiled the complete kernel, then created a hpfs directory in the correct location under /lib/modules/ and copied hpfs.ko into it and ran depmod, but when if run modprobe hpfs, I get a fatal error due to an invalid module format. I am using the 8kstacks kernel from Linuxant, so I changed the EXTRAVERSION in the Makefile to -1.358.8kstacks so I would match the installed kernel.. Is there something else that I need to do?
