Others have answered with good answers already, but there is also another simple reason for a detected version mismatch. When you install the stock Red Hat kernel source package, the makefile contains the following line: $ grep -i extra /usr/src/linux-2.4/Makefile EXTRAVERSION = -19.8.0custom (In other words, the 'custom' tag is added to the EXTRAVERSION define.) Modules compliled against the kernel source, which should work fine for the 2.4.18-19.8.0 (for example) kernel, will complain about a mismatch, since the module is compiled for the 2.4.18-19.8.0custom kernel. If that's the case, the error message is pretty useful, something along the lines of: "module is for kernel 2.4.18-19.8.0custom, while the running kernel is 2.4.18-19.8.0" I suppose Red Hat adds the 'custom' tag to prevent people from wiping out their current modules directory when running make modules_install. It does however cause problems of it's own when trying to build a single module. I know this is the case here, where I have an ethernet module I have to rebuild from source at each kernel upgrade. More than once, I've forgotten to edit the kernel makefile only to find that the module refuses to load after booting into the new kernel. - -- - -Michael pgp key: http://www.tuxfan.homeip.net:8080/gpgkey.txt Red Hat Linux 7.{2,3}|8.0 in 8M of RAM: http://www.rule-project.org/ - -- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE+JLbQn/07WoAb/SsRAlZrAJ9SjYiw2V7C1IrCQTQReFauShvpsgCgtUsQ t1m6nquIDcDB74oRlWn6jes= =TT39 -----END PGP SIGNATURE----- -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
