Then I tried to apply kernel patch-2.2.13.gz on 2.2.12-20 kernel using ../scripts/patch-kernel like it written in README and got something like this: Reversed (or previosly applied) patch detected! Skipping patch. n out of n hunk ignored -- saving rejects to <some file>.rej .... .... failed. Clean up yourself. Is it possible to apply kernel patches at all? Probably original kernel is modified by RedHat and can't be updated by original kernel patches. Why RedHat can't release complete rpm's for newly available kernels?
Kernels based on 2.2.13 and 2.2.14 have been in Raw Hide for a while.
