The "bug" is still there, just not triggerable anymore on amd64 and
i386. I use "bug" as when faking the kernel version to change the result
of versions comparisons, one should expect the result of such
comparisons to be wrong.

The host might runs jessie, but from the bug report I understood the
bug happened in a testing or sid chroot.

We lowered the minimum required kernel version to 2.6.32 instead of 3.2
on amd64 and i386. When comparing kernel versions with the uname26
personality, we have the following relations when the minimum kernel
version is 2.6.32:
- 3.x kernels aka 2.6.40+x > 2.6.32, this works
- 4.x kernels aka 2.6.60+x > 2.6.32, this works

However when the minimum kernel version is 3.2:
- 3.x kernels aka 2.6.40+x < 3.2, this do not work
- 4.x kernels aka 2.6.60+x < 3.2, this do not work

On amd64 and i386 it should be safe.
