kernel panic when get ip through BOOTP!

Thu Apr 26 18:59:36 EST 2001

Maybe, your tcp/ip stack works properly but your physical ethernet interface doesn't.
Check your port mapping in arch/ppc/mbxboot/commproc.h.

#define PB_ENET1_RXD    ((uint)0x00000004
#define PB_ENET1_TXD    ((uint)0x00000002

Thank you.
