I applied you diff and ran the test again.. your patch with LOCKDEP enabled: ipcs.strace.1 - strace of ipcs from the first run ipcs.kernel.out.1 - kernel logs from 1st strace ipcs run ipcs.kernel.out.2 - kernel logs from 2nd strace ipcs run - system freezed your patch with LOCKDEP disabled: ipcs.kernel.out-NO_LOCKDEP.1 - kernel logs from 1st strace ipcs run - system freezed maybe I overlooked smth, but following is the only way I found how to disable LOCKDEP, hope it is fine... let me know: diff --git a/arch/x86/Kconfig b/arch/x86/Kconfig index 80b7ba4..2bfd8dc 100644 ---
