Please let me know what should I do to help tracking this issue. Can you build two kernels: one with -fwrapv, and one with -fno-strict-overflow, and then verify that - they are otherwise identical (ie exact same source code, same compiler etc) - verify that yes, the -fwrapv kernel works, the other does not. Just to avoid the confusion that obviously exists with Debian/sid binutils upgrades that _also_ happens result in nonbootable kernels. - upload the 'vmlinux' images somewhere (I'm not sure what the limits for binary attachments are at the kernel bugzilla, but that would be the logical place) In fact, it would be nice to have a third "identical" kernel build, except with neither -fwrapv/-fno-strict-overflow.
