The cvsup timestamps are 5 minutes apart for the good and bad
kernels. If this is a memory alignment issue, then your patch
would need to replicate the old alignment. That is, this is
similar to the old Fortran issue that a simple debugging
print statement can suddenly make code work because an array in
memory has moved and stepping off the end of the array doesn't
touch already used memory.
I wonder if memguard might help. I'll go read up of this.
