I'm seeing this same problem (well, the symptoms are the same) on a
6-stable amd64 system (cvsup'd today). If I include atapicam in the
kernel the system panics on boot (after the "ATA PseudoRAID loaded"
message and before the "Trying to mount root ..." message). If I remove
atapicam from the kernel everything is fine unless I kldload atapicam.
A short while after loading atapicam (takes a few minutes to panic) it
then panics with the same panic message:

panic: g_read_data(): invalid length 3179371452
