Requesting interrupt using level triggering flag hangs the system because the interrupt handling routine is called continually. Using edge triggering avoids this problem. As a result, disabling interrupt may not be necessary. > > Signed-off-by: Tristram Ha You say "may not be necessary", do you actually know for sure? This seems questionable, if the interrupt disabling was there for a reason what has changed to make it such that it is no longer necessary? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
