Linux 2.4.24 on PQ2FADS

Dear colleagues,

I'm trying to have Linux 2.4.24 working on my evaluation board PQ2FADS-VR
with ppc8275, but I'm suffering of a lot of instability problems.
The Boot-loader I use is Uboot-1.0.0 witch initialise correctly the board
at speed 66,133,199 and correctly fills bd_info struct.
But when I issue the command "=> bootm 100000" I observe every time a
different behaviour: sometimes I don't see anything, sometimes the board
stops in "Calibrating delay loop", sometimes after having written the line:

Memory: 30936k available (984k kernel code, 344k data, 52k init, 0k

Or the line

POSIX conformance testing by UNIFIX

Only occasionally it reaches the init program (stopping here).

The same behaviour I observed with the images delivered by the Arabella

Do you have any suggestion? MMU? Cache? Hardware?

Thanks in advance for your advice.

With best regards,
