Golang on Linux was not yet using the new year 2038 proof syscalls on 32-bit systems, leading to crashes on >=5.0 kernels without 32-bit compat. I filed an issue and went on to implement that.
Reference commits where Linux added the new 64-bit syscalls:

This test is based on the patches from https://github.com/torvalds/linux/compare/master...bjoto:linux:kexec-image-v2-fixup. I have ported them both to 6.9.7 and 6.10-rc6 with success.
