atapicam prevents boot, system hangs

If atapicam is included Freebsd 5.3 release, 5.4 pre1 and 5.4 pre 2 will 
hang just before the SMP startup notice in the dmesg trace.  If atapicam is 
removed then the system boots normally.   The message it hangs on in place 
of the SMP message is an interrupt storm on int 18: em0 and 
uhci2++.  Scrolling still works, no recovery ever happens.

System is a P4 Asus P4C800-E, no AGP video, digital camera disks on the USB 
port .

I'm a bit of a newbie to all this, hope I've posted notices the right way 
to the right spots.
