OK, thanks. And we know that
x86_64-mm-re-positioning-the-bss-segment.patch triggered this failure. And
that patch is non-buggy, and the xfrm code is probably non-buggy. So we don't
know squat, and we're going to need to debug this crash.
Well. There is one trick we could use: apply
x86_64-mm-re-positioning-the-bss-segment.patch to 2.6.18 base and see if it
crashes. If it doesn't, then we can theorise that the bug is some buggy
post 2.6.18 patch which is being exposed by
x86_64-mm-re-positioning-the-bss-segment.patch. A technique I've used
before for identifying the buggy patch is to do a git-bisect, but apply
x86_64-mm-re-positioning-the-bss-segment.patch by hand at each bisection
step. It's pretty straightforward as long as the patch roughly applies at
each step.
Or we could debug it. Can you send the .config? Let's see if it happens
with my toolchain+machine first.
Thanks.
