I get a *lot* of these:
(swapper/0): 996us non-preemptible critical section violated 100 us preempt threshold starting at schedule+0x55/0x5a0 and ending at do_IRQ+0x110/0x180 [<c0106717>] dump_stack+0x17/0x20 [<c0113eec>] dec_preempt_count+0x3c/0x50 [<c0107a20>] do_IRQ+0x110/0x180 [<c01062d8>] common_interrupt+0x18/0x20 [<c0104222>] cpu_idle+0x32/0x50 [<c030a782>] start_kernel+0x1a2/0x1f0 [<c010019f>] 0xc010019f
This has to be a false positive, because if there were really ~1ms non-preemptible critical sections all over the place I would be getting xruns.
