On every new system its always a black art to untangle the IRQ's. Its
almost impossible to not have shared lines here or there. In most cases
up to now I have managed to get an acceptable compromise using every
single one of the possible tricks (including beating our engineers who
have nothing whatsoever to do with the hardware but it helps relieve the
frustration). I was wondering -and am using this opportunity to post the
question- what the fundamental problem is that makes shared IRQ's
between RTdevices and non-RT devices crash the system? And whether I
understand correctly that later versions (2.4 up?) of xenomai do not
have the problem of the freezing system at least.?
