Hi Guys,

Is this the right place to be discussing this?  If not, let me know.

FYI, I am on x86_64.

This bug is very debilitating for me, especially on my home system.
So, I recently read about "git bisect", when I was reading an xorg
bug.  So, I thought hey, I should give that a try to try and narrow
down which kernel version gives me a problem.  That would certainly
help you guys in finding this EXACT issue, and me getting a reasonable
fix. :D

Anyhow, I started with cloning Linus' git kernel tree, and then
checking out 2.6.17.  2.6.17 was working for me on my work machine
when I was using gentoo 32-bit, so I thought that was a good place to
start.  It seems like it's better performance.

So, before starting the git bisect stuff, I wanted to try an earlier
version.  So, I checked out 2.6.16, but it refuses to compile.  Can
someone help me?

FYI, I did an mrproper, and then copied my config back to ".config".

  AS      arch/x86_64/ia32/vsyscall-sysenter.o
  SYSCALL arch/x86_64/ia32/vsyscall-sysenter.so

Thanks.
