[CentOS] boot issue

I had to reboot this morning (Dual core AMD 4800+)
the machine did not reboot... I thought great its monday.
Tried looking at BIOS revisions, looking at BIOS settings,
tried changing some and booting again etc... nothing worked.

My machine was locking up at
Initializing Storage, network audio.

I finally noticed I had a thumbdrive in the usb connector.
I removed the thumbdrive and the machine booted.

Just wanted to share in case someone else gets stuck there.

Have a great monday.
