Not much to offer. I've got syslog writing to flash but it's not seeming to capture anything useful. Services all start up, finds some parity problems, and then the fresh boot.
I've got a picture of one of the bad boots from a couple days ago. It seems to run fine for a week or so and then get these error bouts and lockup every couple of hours. Usually during the parity check.
