Hi
Looks like there is some problem in mapping of serial
port interrupt. Because after booting the kernel
serial port will work in interrupt routine.Now u have
to verify two things :

1. in openpic what is the interrupt vector for serial
port.
2. Same interrupt vectupr u have to program in ur
serial.h file.....

may be u will have a success if not send me ur
sandpoint_setup.c & openpci_irq.c & kernel booting
message.


Thanx

I'm having problems getting linuxppc-2.5 running on
an X2 Sandpoint system. Firstly there are a couple
of failures
during the build relating to changes in the
interrupt handling. I've made the obvious changes in
sandpoint_setup.c

openpic_init(1,0,NULL,-1) -> openpic_init(0)
i8259_poll() -> i8259_irq(regs)

The kernel boots, mounts file system etc...  but
after "Freeing unused kernel memory: 96k init" no
prompt - Initial
debug shows that the kernel is executing some of the
interrupt routines (sandpoint_get_irq(),
openpic_irq() etc ).
However I'm not sure if this is indicative of an
error in the changes above or just the fact that the
kernel isn't doing
anything else but service irq's.

Any help/pointers would be gratefully received.
