System freezes with Comedi & RTAI & framegrabber

Hi all, I've submitted this problem to the RTAI list but it concerns 
Comedi as well. I've not been able to get RTAI, video4linux, and comedi 
all working at the same time (i.e. pick 2). I have a bt8x8 framegrabber 
supported by video4linux, in kernel 2.4.20 (red hat 9 + previous 
version of rtai + comedi stable) and 2.6.8.1 (ubuntu 5.04 + latest rtai 
and comedi stable).

In Red hat/kernel 2.4: When the framegrabber is installed, I can load 
the RTAI modules into the kernel successfully. However when I attempt 
to load the comedi drivers, the system immediately freezes/reboots.

In Ubuntu/kernel 2.6: When the framegrabber is installed, I cannot load 
the RTAI modules, when I do, the system immediately reboots.

If I just remove the framegrabber, the 2.6 kernel loads RTAI and Comedi 
just fine. I can also use the framegrabber with RTAI in kernel 2.4, 
however I cannot use the data acquisition hardware.

Anyone have any idea what is going on, and can help me debug this 
issue? I fear that I'll have to use two networked computers for this 
robotic task (one computer streams video to the other with the data 
acquisition).
