No, that was ony added in 2.6.18-rc1 (and the fix was only added
post-rc3), so that can't be it..

    I am not sure of the details, but I had the exact same problem, I used "git bisect" to isolate it.
    and it bisected down to the Zlib patch I backed that out and I was able to go from 2.6.16.21. all the way to 2.6.18-rc2.
