I figured it would take a little reworking, especially with your recent MSI changes. This was just a 'works for me' patch.

No lockups. No jack xruns. Max wakeup-latency is 27us (so far) on the debug config. Nothing out of the ordinary logged except for the new stack-footprint maximums during boot. Any need to go back and check -51-16 as well? Or -51-17 on a non-debug config? --ww - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
