At which point the rebooting is simply stuck. I can wait ages and it still does not reboot.
Any advice?
Looks like software needs fixing.
John
Hey,
When facing issues like this please provide some basic information so people are able to help you. For example:
1. What board and what revision are you using?
2. How do you power the board?
3. What image are you using? Does the behavior remains with the Debian Wheezy image?
4. Does it occur during first power-up or after issuing a shutdown/restart/reboot command?
Best regards,
Lub/OLIMEX
