Hi Anders; apologies for missing your post earlier. You and Brian both suggested dkms, but the problem with dkms is that if it fails, the system will just fail to reboot - which means physically going to the lab to fix things, and would be a disaster if I am overseas. So I think sticking with manual building is necessary. Thanks for the point about devel; but it isn’t the cause of the problem - I always wait to rebuild until kernel headers and devel for the new kernel are available (the local mirrors are sometimes a bit slow to update, so I’m very aware of the risk of mismatched latest versions). By manually rebuilding, I can see that the build failed while I’m still in a running system, and I can usually repair and reboot to the preceding system when it fails. Since I’m usually doing this remotely, that’s a really important plus. Anders Blomdell said... Use appropriate scripts in /etc/kernel/postinst.d or /etc/kernel/postinst.d/dkms and kernel modules can be rebuilt right after a new kernel is installed (of course you need kernel-devel). /Anders _______________________________________________ Yum mailing list Yum@xxxxxxxxxxxxxxxxx http://lists.baseurl.org/mailman/listinfo/yum
