First, I apologize. I see that you were assuming I had KEXEC enabled when you gave me the patch against 2.6.27-rc3. I have only posted parts of my custom .config to LKML, thinking that posting the whole thing was not appropriate.
Did you mean CRASH_DUMP instead of "kdump" above?
[N] kexec system call (CONFIG_KEXEC) (bool) (Help) [N] kernel crash dumps (EXPERIMENTAL) (CONFIG_CRASH_DUMP) (bool) (Help)
My custom .config has both of these disabled -- either because they default to "N" when running 'make oldconfig', or because I read the help text with those options and decided I would not be using those features.

I will try your patch against 2.6.27-rc3 again, with KEXEC and CRASH_DUMP enabled, when I get home from work. I still have not retried using 'patch' instead of 'git apply', though I am sure that 'git apply' worked just fine.
I was trying other experiments last night, and have posted the results of those already -- and I'm guessing that your 2.6.27-rc3 patch will not work unless it factors in what I discovered there. (But I will do all of these changes that you asked, as well.)
I do not know how to bisect with your patch if I have a "bad" but no "good" to start with. Can you explain how I should proceed when I _do_ get home? (I can just enabled those config options and try the patch again, but I am confused about the bisect you are asking me to perform.)
Does my other post, about trying to revert those February commits, mean anything?
Thanks, Dave W.
