If you are building your own kernels, make sure that you don't accidentally turn on CONFIG_DEBUG_PAGEALLOC in your .config. You can check this by doing a 'grep CONFIG_DEBUG_PAGEALLOC /usr/src/linux/.config'. It should not be set. I speak from recent experience with this matter; I enabled debug in my config so that I could use the sysrq key. Unknowingly, I turned on pagealloc debug also (the default if debug is enabled) - and it took me a little while and some effort to track the problem down. I checked the stock FC4 kernel, and it of course does not have this config set. But be wary if building your own kernel. -Dan -- Dan A.
