Hang on Boot if Verbose is not enabled

[rooskie54]

I've had a working install of OSX 10.6.3 (installed with iAtkos S3v2) on an Emachines T6520 (yeah it's terrible) for a week and a half now. Somewhere in the past 48 hours it's started to hang on boot. When it first did it I rebooted with verbose mode enabled and it loaded up to Finder just fine so I didn't look into it anymore. Then the problem repeated itself on the next reboot and once again booting with -v got it to start up just fine.

 

For the time being I've edited the boot file so it will automatically enable verbose mode. I'm just confused as to why verbose mode solves the problem. I was under the impression that all it did was show you whats going on behind the scenes and not actually changing anything in the boot process. Can anyone tell me otherwise?

 

I'm more than happy to provide any extra information or logs (gonna need to know the location of the logs though.)
