The stack tracer triggered the assert in module_assert_mutex_or_preempt(), which checks that rcu_sched is used as protection, as __module_address() is protect with a synchronize_sched(). The problem with this, is that the WARN_ON() triggers a stack dump which also calls __module_address() and triggers the same warning. All I had to debug this was the following over and over. ------------[ cut here ]------------ WARNING: CPU: 5 PID: 0 at /home/rostedt/work/git/linux-trace.git/kernel/module.c:291 module_assert_mutex_or_preempt+0xa0/0xb0() Modules linked in: be2iscsi iscsi_boot_sysfs bnx2i CPU: 5 PID: 0 Comm: swapper/5 Not tainted 4.2.0-test+ torvalds#138 Hardware name: Hewlett-Packard HP Compaq Pro 6300 SFF/339A, BIOS K01 v02.05 05/07/2012 ffff88011945ba78 ffff88011945ba78 ffffffff8184d08f 0000000000000000 0000000000000000 ffff88011945bab8 ffffffff810ac1b7 ffff88011945baa8 0000000000000001 ffffffffa0080077 ffffffff81a04410 0000000000000000 Call Trace: [<ffffffff8184d08f>] dump_stack+0x4f/0xa2 [<ffffffff810ac1b7>] warn_slowpath_common+0x97/0xe0 ------------[ cut here ]------------ WARNING: CPU: 5 PID: 0 at /home/rostedt/work/git/linux-trace.git/kernel/module.c:291 module_assert_mutex_or_preempt+0xa0/0xb0() Modules linked in: be2iscsi iscsi_boot_sysfs bnx2i CPU: 5 PID: 0 Comm: swapper/5 Not tainted 4.2.0-test+ torvalds#138 Hardware name: Hewlett-Packard HP Compaq Pro 6300 SFF/339A, BIOS K01 v02.05 05/07/2012 ffff88011945b768 ffff88011945b768 ffffffff8184d08f 0000000000000000 0000000000000000 ffff88011945b7a8 ffffffff810ac1b7 ffff88011945b798 0000000000000001 ffffffffa0080077 ffffffff81a02e10 0000000000000000 Call Trace: [<ffffffff8184d08f>] dump_stack+0x4f/0xa2 [<ffffffff810ac1b7>] warn_slowpath_common+0x97/0xe0 ------------[ cut here ]------------ WARNING: CPU: 5 PID: 0 at /home/rostedt/work/git/linux-trace.git/kernel/module.c:291 module_assert_mutex_or_preempt+0xa0/0xb0() Modules linked in: be2iscsi iscsi_boot_sysfs bnx2i CPU: 5 PID: 0 Comm: swapper/5 Not tainted 4.2.0-test+ torvalds#138 Hardware name: Hewlett-Packard HP Compaq Pro 6300 SFF/339A, BIOS K01 v02.05 05/07/2012 ffff88011945b458 ffff88011945b458 ffffffff8184d08f 0000000000000000 0000000000000000 ffff88011945b498 ffffffff810ac1b7 ffff88011945b488 0000000000000001 ffffffffa0080077 ffffffff81a02e10 0000000000000000 I first tried to switch the WARN_ON() to a WARN_ON_ONCE() but that didn't help because the flag within WARN_ON_ONCE() is set after the stack dump, which means that it didn't solve the issue.
