Subject: SystemACE driver problem

Hello

I'm trying to boot a Linux Kernel 2.6.23-rc2 from Grant Likely (thanks for
the great work) on a Xilinx ML403 board. I want to use the second partition
of the Compact Flash Card as root filesystem. But the boot process hangs at
the initialization of the SystemACE module. A strange effect is that the
DONE LED (configuration of the FPGA is done) turns off. So, this means that
the FPGA loses his configuration.
Has anybody recognized a similar problem with the SystemACE module??

The boot log:
