Lock up on boot with LS-120 and CURRENT

Hi,

Using todays current, I'm finding that FreeBSD locks up completely on 
boot if I don't have a disk in my LS-120 drive. There is no panic, it 
just seems to freeze. I have included a dmesg from a boot with a disk in 
the drive and indicated the point at which it freezes without the disk 
in. It worked fine on 5.1-RELEASE. I have atapicam in the kernel.

Any ideas as to what may be causing this?

Mark
