Something went wrong somewhere.

I did the AMD Updater fine

Loaded the non-combo 10.5.3 updater from apple and it froze my machine through it. Tried to reboot and it began giving USBEHCI errors and sync'd my disks and rebooted. Tried disabling legacy mode and setting that partition active and it took away the USB errors but still persistion on rebooting without much info.

Off to reinstall and tinker
