uhub2 port 5 reset failed help

Sat Jan 19 10:05:04 PST 2008

Hi, I am using FreeBSD 6.2 i386.  When I first got FreeBSD installed on this computer is worked perfectly until a few days ago I got, "usb2: port reset timedout; uhub2: port 5 reset failed".  The only way I can get it to start up without rebooting is to start it up in safe mode.  Any one have a fix?  Also, I have a AMD Sempron Processor and not a i386 Processor (Intel).  Could that be the problem?  I have also disabled all usb drives in the bios, and all ports I don't use.  I have just begun downloading FreeBSD AMD64.  Thanks for your help.
