linuxppc-2.4.30-pre1 crashes with root fs on Xilinx SystemACE

Hello - 
Per a previous suggestion from this list, I rsynced the linuxppc-2.4 
kernel sources from MontaVista and modified the kernel to run on my custom 
ppc405/VirtexII Pro based system with U-Boot as the bootloader.
When I try to use the SystemACE device as the root filesystem, the kernel 
crashes with a sig 11.  Looking at the 'oops' output it appears  the 
SystemACE driver may be to blame.  The crash is random - sometimes I get 
all the way to login as root and then things crash on a file copy or a 
file read.
Before I start digging deeper, is anyone running a VirtexIIPro based 
system with the root filesystem in the CF card attached to a SystemACE? 
I'm wondering if I really have the best kernel and SystemACE driver.
BTW, I'm developing the hardware design using Xilinx EDK 7.02i.
Thanks,
Keith
