With lockdep we got the following trace after a panic: Badness at /home/autobuild/BUILD/linux-2.6.28-20090204/kernel/lockdep.c:2878 [...] Call Trace: [<0000000000176334>] lock_acquire+0x54/0xbc [<000000000050b4fe>] __atomic_notifier_call_chain+0x6e/0xdc [<000000000050b59c>] atomic_notifier_call_chain+0x30/0x44 [<0000000000504274>] panic+0xd0/0x1e8 [...] INFO: lockdep is turned off. Last Breaking-Event-Address: [<0000000000170e62>] check_flags+0xae/0x15c possible reason: unannotated irqs-off. lockdep is right. We missed a trace_hardirq_off in our smp_send_stop function and smp_send_stop is called before the panic call chain.
