On a PrPMC800 (PPC 7410 processor) withe Xenomai-2.1-rc2, I get the following if
the interrupt handler takes too long (i.e. next interrupt gets generated before
the previous one has finished)
[ 42.543765] [c00c2008] spin_bug+0xa8/0xc4

[ 43.411145] [c0006524] default_idle+0x10/0x60
Any ideas of where to look?
