The first step is always to check if the same issue occurs using the standard Xenomai testsuite, e.g. running the latency and switch tests. Nobody knows what your application is doing and the way it does it, including the kernel module you seem to be using for that purpose; so let's properly segregate issues if need be. Try to reproduce the crash with a freshly patched kernel, without running neither extra modules nor applications. > is there a workaround ? > > general protection fault: 0000 [#1] > PREEMPT > Modules linked in: nls_iso8859_1 nls_cp437 i915 rtcan_sja1000 e100 > usb_storage eepro100 mii rtc unix > CPU: 0 > EIP: 0060:[<c0103112>] Not tainted VLI > EFLAGS: 00010246 (2.6.16.19-ipipe #1) > EIP is at sysenter_exit+0xf/0x11 > eax: 00000010 ebx: 00000000 ecx: b7d1223c edx: ffffe410 > esi: b7d122cc edi: 00000000 ebp: 00000000 esp: dc1a7fbc > ds: 007b es: 007b ss: 0068 > Process EnvoiPDO0 (pid: 1879, threadinfo=dc1a6000 task=de35d030) > Stack: <0>00000000 b7d122cc 00000000 b7d122cc 00000000 b7d12268 00000010 > 0000007b > 0000007b 0802022b ffffe410 00000073 00000206 b7d1223c 0000007b > 00000000 > 00000000 > Call Trace: > Code: 44 24 18 e8 81 ca 03 00 fb 8b 4d 08 66 f7 c1 ff fe 0f 85 4e 01 00 > 00 e8 ed ea 00 00 8b 44 24 18 8b 54 24 28 8b 4c 24 34 31 ed fb <0f> 35 > 50 fc 06 1e 50 55 57 56 52 51 53 ba 7b 00 00 00 8e da 8e > <0>general protection fault: 0000 [#2] > PREEMPT > Modules linked in: nls_iso8859_1 nls_cp437 i915 rtcan_sja1000 e100 > usb_storage eepro100 mii rtc unix > CPU: 0 > EIP: 0060:[<c0103112>] Not tainted VLI > EFLAGS: 00010246 (2.6.16.19-ipipe #1) > EIP is at sysenter_exit+0xf/0x11 > eax: 00000000 ebx: 00000000 ecx: b7ce6a2c edx: ffffe410 > esi: 00669627 edi: 00000000 ebp: 00000000 esp: d704ffbc > ds: 007b es: 007b ss: 0068 > Process Automat (pid: 1882, threadinfo=d704e000 task=d701b030) > Stack: <0>00000000 00000001 b7d8a660 00669627 00000000 b7ce6a58 00000000 > 2801007b > 0000007b 0801022b ffffe410 00000073 00000206 b7ce6a2c 0000007b > 00000000 > 00000000 > Call Trace: > Code: 44 24 18 e8 81 ca 03 00 fb 8b 4d 08 66 f7 c1 ff fe 0f 85 4e 01 00 > 00 e8 ed ea 00 00 8b 44 24 18 8b 54 24 28 8b 4c 24 34 31 ed fb <0f> 35 > 50 fc 06 1e 50 55 57 56 52 51 53 ba 7b 00 00 00 8e da 8e > > _______________________________________________ > Xenomai-core mailing list > Xenomai-core@gna.org > https://mail.gna.org/listinfo/xenomai-core -- Philippe. _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
