it looks as though your configuration may be hanging so if you can boot the router without loading the configuration, you may be able to at least get to the router prompt and browse around, change config, etc.
Did you try to write erase the config and boot up fresh. This would rule out there's nothing in the config that could be causing this behavior. The reason I am saying is that I see the iomem is manually set to 7% and I believe the default is 20%.
If that doesn't help, remove all modules and boot up the router and if it boots up fine then starting putting in the modules one at a time and this would help isolating the problem. If the router doesn't boot up with no modules inserted then I am afraid you may have a faulty router. I hope that's not the case.
Does it hang for good at times or does it take a long time to finish booting? If it simply takes a long time to boot then I am going to say it's probably the result of wear and tear. I used to have a old 2500 (ofcourse, i bought it in ebay as well:))in my lab and would take a good 5 mins to finishing booting up.
As far as your question about iomem is concerned the router allocates memory for input/output (iomem) and processes. By default, the router allocates 20 or 25% for input/output and the rest for processes. If you already did a 'write erase' and rebooted the router then everything should have been restored to the default. There's another option called 'smart init' where the router dynamically allocates memory. I don't know if it's turned on by default in the version of code you are using.
