    SubjectRe: Regression? 2.6.27-rc3 segfault on cold boot; not on warm boot.

    Yes, below is a netconsole boot of 2.26.6.3

    I cold booted - lots of segfaults. I then did a ctrl-Alt-SysRq-S-U-B to a warm
    boot. No segfaults
    (lots of #### mark the split)

    I've just started 2.6.25.14 building for tomorrow to confirm how far back it
    goes. (I'm 99% sure 2.6.25 is OK)
