Here's a list of tries, where S means I issued shutdown -r P means I had to powercycle R means I issued a reset to u-boot L means the Pi got stuck in a loop U means usb reset was issued M means the Pi stopped at mountroot (self-reset) B means I issued a boot at the loader prompt The sequence was: PRSSSSBSSSSULPMSSM I've placed the log script at http://nemesis.zefox.com/~fbsd/ with mountroot in the filename.
