Hi list,

I've just downloaded linux-2.4.31 from kernel.org and compiled it for
the mpc8272ads board.

When I boot the kernel it oopses in fcc_enet.c:init_fcc_startup() at
the point where it tries to write to the BCSR.

Does anybody know why writing to the BCSR should cause a machine
check?

TIA,

Alex
