Stuck in booting 2.6.10-ac11 on Memec Design FF1152...

Hello everyone!

I seem to be promptly stuck at a place in booting (and has been for a while now) so I figured I'd ask the list and see if anyone of you has any ideas. This is all on a Memec Design FF1152 Rev. 3 Evaluation board containing a XC2VP20 Virtex-II pro chip (two ppc 405GP processors). Since the excellent Xilinx tools crash on ELF files, the only option is to download a binary and debug using the serial port.

After enabling SERIAL_DEBUG_IO_BASE to the serial port, the last printout is "MMU:exit()". Checking the PC and the System.map, I seem to halt in the function __delay() which I believe is the function in arch/ppc/kernel/misc.S since it's global. Now, I have two problems:

1. How does it get to (and get stuck in) __delay()? Can it be triggered by some interrupt if the controller isn't properly configured or is it called from init/main.c and there is some missing timer (initialization)? Looking at Andrei Konovalovs ML300 setup I can't see any external timer configured...

2. gen550_progress() (or something else) seem to be hogging the console (serial port) one way or the other, disabling printk() and making it much harder to debug. Any suggestions how I could deal with this? The serial device is a generic 16550 UART (Xilinx made).

Thanks in advance!

(PS. Andrei: You seem to be using a DCR_INTC on your card and yet setting the parameter USE_DCR set to 0. Why is that?)
