I just installed the new kernel RPMS from rawhide: kernel-2.2.12-11 kernel-headers-2.2.12-12 kernel-source-2.2.12-11 Unfortunately, the source and binary are revision -11, but the headers are revision -12. This mismatch is preventing modules that I'm compiling (specifically, vmware) from being able to "insmod" into the kernel.
This was fixed some time ago.
