Hi, we've done some start/stop tests with our xenomai system 2.6.29.5 with Xenomai 2.4.9.1 on a SMP x86.
Sometimes on boot we get these messages: [ 28.474265] BUG: scheduling while atomic: ps/3549/0x10000100 [ 28.474269] Modules linked in: ec_e1000e ec_master [last unloaded: e1000e] [ 28.474283] Pid: 3549, comm: ps Not tainted (2.6.29.5-xenomai-2.4.9 #8) [ 28.474287] EIP: 0060:[<c113df82>] EFLAGS: 00000206 CPU: 1 [ 28.474296] EIP is at selinux_dentry_open+0x1/0xb8 [ 28.474299] EAX: 00000000 EBX: 00000000 ECX: 00000000 EDX: 00000000 [ 28.474303] ESI: 00000000 EDI: 00000000 EBP: ead8bea4 ESP: c1ef9638 [ 28.474307] DS: 0000 ES: 0000 FS: 0000 GS: 0033 SS: 0068 [ 28.474310] CR0: 8005003b CR2: b7ea6000 CR3: 2ad6d000 CR4: 00000690 [ 28.474314] DR0: 00000000 DR1: 00000000 DR2: 00000000 DR3: 00000000 [ 28.474317] DR6: ffff0ff0 DR7: 00000400 [ 28.474320] Call Trace: The trace stops here, so we don't see any calltrace. after evaluating some of these messages, we found out, that they have maybe something to do with networking.
