Is CONFIG_FRAME_POINTER enabled for your kernel, i.e. can we trust the backtrace below? Additionally, what happens if you stop asking rt_task_set_mode() to clear primary mode via toggling the T_PRIMARY flag? (which you should very likely NOT do, btw. Forcing the current mode is counter-productive most of the time; this is an internal feature for very, very specific needs of some Xenomai library code). > ar 5 15:08:22 (none) user.err kernel: I-pipe: Detected illicit call > from domain 'Xenomai' > Mar 5 15:08:22 (none) user.err kernel: into a service > reserved for domain 'Linux' and below. > Mar 5 15:08:22 (none) user.warn kernel: Pid: 990, comm: main thread > Not tainted 2.6.27.19-standard-xenomai #1 > Mar 5 15:08:22 (none) user.warn kernel: [<c0146d3d>] > ipipe_check_context+0x8d/0xb0 > Mar 5 15:08:22 (none) user.warn kernel: [<c0115535>] > sub_preempt_count+0x15/0x80 > Mar 5 15:08:22 (none) user.warn kernel: [<c0115e1e>] > finish_task_switch+0x2e/0x80 > Mar 5 15:08:22 (none) user.warn kernel: [<c01172ba>] > ipipe_reenter_root+0x1a/0x60 > Mar 5 15:08:22 (none) user.warn kernel: [<c0155a2d>] > xnshadow_relax+0x9d/0x100 > Mar 5 15:08:22 (none) user.warn kernel: [<c015e9b7>] > __rt_task_set_mode+0x67/0x90 > Mar 5 15:08:22 (none) user.warn kernel: [<c0155dd7>] > losyscall_event+0xb7/0x170 > Mar 5 15:08:22 (none) user.warn kernel: [<c0155d20>] ? > losyscall_event+0x0/0x170 > Mar 5 15:08:22 (none) user.warn kernel: [<c0148150>] > __ipipe_dispatch_event+0xd0/0x220 > Mar 5 15:08:22 (none) user.warn kernel: [<c010d54a>] > __ipipe_syscall_root+0x3a/0xe0 > Mar 5 15:08:22 (none) user.warn kernel: [<c010320b>] system_call+0x2b/0x4c > Mar 5 15:08:22 (none) user.warn kernel: ======================= > Mar 5 15:08:22 (none) user.warn kernel: ------------[ cut here ]------------ > Mar 5 15:08:22 (none) user.warn kernel: WARNING: at > kernel/sched.c:4322 sub_preempt_count+0x7d/0x80() > Mar 5 15:08:22 (none) user.warn kernel: Modules linked in: ipv6 > eepro100 mii genrtc usb_storage nls_iso8859_1 nls_cp437 > Mar 5 15:08:22 (none) user.warn kernel: Pid: 990, comm: main thread > Not tainted 2.6.27.19-standard-xenomai #1 > Mar 5 15:08:22 (none) user.warn kernel: [<c011b746>] > warn_on_slowpath+0x46/0x60 > Mar 5 15:08:22 (none) user.warn kernel: [<c010320b>] ? system_call+0x2b/0x4c > Mar 5 15:08:22 (none) user.warn kernel: [<c011cc71>] ? printk+0x41/0x180 > Mar 5 15:08:22 (none) user.warn kernel: [<c0103c85>] ? > show_trace_log_lvl+0x25/0x30 > Mar 5 15:08:22 (none) user.warn kernel: [<c0101e5a>] ? __switch_to+0xa/0x150 > Mar 5 15:08:22 (none) user.warn kernel: [<c0146d42>] ? > ipipe_check_context+0x92/0xb0 > Mar 5 15:08:22 (none) user.warn kernel: [<c0115535>] ? > sub_preempt_count+0x15/0x80 > Mar 5 15:08:22 (none) user.warn kernel: [<c011559d>] > sub_preempt_count+0x7d/0x80 > Mar 5 15:08:22 (none) user.warn kernel: [<c0115e1e>] > finish_task_switch+0x2e/0x80 > Mar 5 15:08:22 (none) user.warn kernel: [<c01172ba>] > ipipe_reenter_root+0x1a/0x60 > Mar 5 15:08:22 (none) user.warn kernel: [<c0155a2d>] > xnshadow_relax+0x9d/0x100 > Mar 5 15:08:22 (none) user.warn kernel: [<c0155e08>] > losyscall_event+0xe8/0x170 > Mar 5 15:08:22 (none) user.warn kernel: [<c0155d20>] ? > losyscall_event+0x0/0x170 > Mar 5 15:08:22 (none) user.warn kernel: [<c0148150>] > __ipipe_dispatch_event+0xd0/0x220 > Mar 5 15:08:22 (none) user.warn kernel: [<c010d54a>] > __ipipe_syscall_root+0x3a/0xe0 > Mar 5 15:08:22 (none) user.warn kernel: [<c010320b>] system_call+0x2b/0x4c > Mar 5 15:08:22 (none) user.warn kernel: ======================= > Mar 5 15:08:22 (none) user.warn kernel: ---[ end trace 37b08dd71b141ea9 ]--- > Mar 5 15:08:22 (none) user.emerg rtlogd: : StopScan() > > Thanks, > > Mark > > _______________________________________________ > Xenomai-help mailing list > [email protected] > https://mail.gna.org/listinfo/xenomai-help > -- Philippe. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
