I am seeing a kernel panic with 4.16-rc1 and 4.16-rc2 kernels when running selftests from tools/testing/selftests. Last messages from selftest before kernel panic are:

Same selftest does not cause panic on 4.15. git bisect pointed to commit 6ce711f2750031d12cec91384ac5cfa0a485b60a ("idr: Make 1-based IDRs more efficient"). Kernel config is attached.
Looks like something horribly wrong with u32 key id idr...
