Volatility vs Stability?

Perhaps stability is not the correct word, how about Volatility? We had an issue with several Dell servers and the Adaptec Raid controller driver present in the 2.6 series of kernels. Solution? We ran 2.4 kernels for 2.5 years until Kernel 2.6.15 appeared with a fixed (completely rewritten) driver. There were a few different versions of the Adaptec Raid driver in 2.6, none of which worked until the rewrite in 2.6.15.
We have live CD firewall/routers running on 2.4, (Devil linux), compiled with grsec etc.. They achieve very long uptimes and have very little volatility. No forced reboots due to the latest 2.6 kernel security patch.
For the first half or kernel 2.4, I ran many systems on kernel 2.2, guess which one was more volatile, more forced reboots, etc.?
