The kernel panics during boot while, it seems, initializing the ATA device. Things work fine with the kernel details shown above (Oct 8th) but fail with a kernel from Oct 10th and also with a fresh kernel from today. The copy/pasted message I see is the following. Please excuse any typos as I had to get this from a very bad-quality picture I took from the screen right before the machine rebooted on its own...
