Is this in the provided passive backplane or a PC motherboard?

Have you been removing/installing the flash chips in the sockets?

Are you changing the clock speed settings?

I had similar trouble when installing an IXP1200 board in an
active backplane with updated flash which explicitly set the
clock speed.

I was using a Rev B0 chip (which should run at 199 MHz) on a
board which was only designed for 167 MHz.  When I inadvertantly
attempted to set the clock to 199 MHz very early in the boot
sequence, I observed the behaviour you describe.  Once I changed
things so that I was only running at 167 MHz, everything was fine.
