Hello, I'm new here, and I don't know how to start. I'm trying to setup an x86 costom platform on Linux RT branch.
Today, I was able to get 2.6.19-rt1 and run some tests. I wrote some module that uses RT API an during modprobe, some thing unexpexted happened: [EMAIL PROTECTED]:~# modprobe someModule [ 257.391000] softirq-tasklet/8[CPU#0]: BUG in rt_mutex_debug_task_free at kernel/rtmutex-debug.c:66 [ 257.391000] [<c0103e68>] dump_trace+0x82/0x20d [ 257.391000] [<c01040cb>] show_trace_log_lvl+0x34/0x4a [ 257.391000] [<c010410d>] show_trace+0x2c/0x2e [ 257.391000] [<c010422a>] dump_stack+0x2b/0x2d [ 257.391000] [<c011930b>] __WARN_ON+0x65/0x77 [ 257.391000] [<c0139c6a>] rt_mutex_debug_task_free+0x4b/0x88 [ 257.391000] [<c01151e4>] free_task+0x21/0x37 [ 257.391000] [<c01152bf>] __put_task_struct_cb+0xc5/0xcb [ 257.391000] [<c0144c61>] rcu_process_callbacks+0x53/0x5e [ 257.391000] [<c011d4fc>] __tasklet_action+0xc9/0xfc [ 257.391000] [<c011d565>] tasklet_action+0x36/0x3b [ 257.391000] [<c011d71c>] ksoftirqd+0xef/0x177 [ 257.391000] [<c012beb7>] kthread+0x90/0xb8 [ 257.391000] [<c0103d2f>] kernel_thread_helper+0x7/0x10 [ 257.391000] ======================= This bug is not critical, but I don't know what to expect from kernel giving me such messages. Is it my fault? This trace do not show any function calling from my someModule. Following debug options are turned on: CONFIG_DEBUG_RT_MUTEXES CONFIG_FUNCTION_TRACE CONFIG_LOCKDEP Just to be sure I'll include full config.gz from running machine. How can I track this bugs myself? What are they assocciated with?
