linux IA 64 kernel does not load

[Surekha.PC]

 Hi,

 I am attempting to boot my itanium 64-bit machine using 2.4.20 linux IA 64
kernel. I followed the following steps to compile the kernel using gcc 2.94:
Install the linux 2.4.20 kernel sources Apply the IA 64 kernel patch Compile
the kernel using the following commands:-
    export LANG=C
    make mrproper
    make CC=/usr/bin/gcc.org menuconfig
    make CC=/usr/bin/gcc.org dep clean vmlinux
 
Then, I manually copied the vmlinux and System.map from
/usr/src/linux-2.4.20/ into /boot/efi/ and created the corresponding links
to vmlinuz and initrd.img into /boot. 
Also, there is no lilo but elilo. So I had to boot the machine, go into the
EFI shell and bring the new vmlinuz-2.4.20 entry in the elilo.conf file into
effect. However, on selecting vmlinuz-2.4.20 at the elilo prompt, the system
hangs at the first step itself. It displays "Loading linux-2.4.20 .... \"
and hangs in the load process itself. 
 
Thanks and appreciate any help,
Surekha

You could run the EFI elilo with "-v" to get more verbosity, but I suspect
that the kernel was loaded into memory fine, and just couldn't find a
console to talk to.

If you're using a serial console, you need to supply something like
"console=ttyS0" (i.e., by using "append" in the elilo.conf file
or using "elilo vmlinux console=ttyS0" at the EFI shell prompt).
The port defaults to 9600 baud; use "console=ttyS0,115200" or whatever
is appropriate if you're using a different rate.  If you're using a
serial console on an HP machine, make sure the EFI console input/output/
error paths contain exactly one serial device (this is configured from
the EFI boot manager menu).
