Sharing an IRQ with both a SATA and a USB controller sets up a situation where I can odd things happening. Changing slots is one wat of getting a different IRQ; your motherboard may also have a way of setting or reserving IRQs in its BIOS. I recall having to try a few different slots before the cards got unique IRQs. I did some searching, and found that you're not the only one with a similar issue. This user had different hardware but very similar errors: http://ubuntuforums.org/showthread.php?t=1580566 One last thing to check, based on my searches - the AssertPort error has been associated with some plugins. You haven't mentioned a client program, so I'm not sure if jack dies before you can start one, or if there's a correlation here. If the errors actually happen after you start something like Ardour, I'd see what happens if you disable the plugins. There are some that will absolutely hammer my system every time I try to use them. They might be from the C* set, but I really can't remember off the top of my head.
