Subject: [Xenomai] rt_task_set_priority hangs/loops sometimes on boot
Date: Fri, 06 Dec 2013 09:03:56 +0100 [thread overview]
Message-ID: <52A184EC.40407@axelsw.it> (raw)
Hi,
sometimes i have a strange behaviour on boot. The kernel hangs. I saw
with an hardware debugger the backtrace when i was in that situation and
i saw this:
probe_irq_off | devm_free_irq
probe_irq_on
probe_irq_on
register_handler_proc
timecounter_read
timer_list_show
posix_cpu_timer_set
stk5_esdhci_init
load_module
exit_irq_thread
__setup_str_setup_slub_nomerge
__setup_str_setup_slub_nomerge
probe_irq_on
probe_irq_on
register_handler_proc
__xnpod_schedule
xnpipe_recv
rt_task_set_priority
The system is in loop/hangs in rt_task_set_priority.
My system has xenomai 2.5.6 on freescale imx25 arm.
Any ideas ?
Thanks for all
