Re: Stock IA64 kernel on SGI Altix 350

	Wow, mail to lkml is way faster than asking local SGI support :-).
Thank you all for fast reply and sorry for posting to the wrong list.

	Thanks, I did not know about sn2_defconfig nor compressed
(I was trying to boot gzip-9'ed vmlinux, which was probably the reason
of why I failed). Is make sn2_defconfig and make compressed documented
anywhere in the kernel sources? I think short Documentation/ia64/README.Altix
or README.sn2 would be helpful.

	However - it still does not work, altough I got at least some
console messages. I have tried both stock 2.6.6 and 2.6.7-rc2-mm2
(make sn2_defconfig, make -j compressed).

... both kernel versions (2.6.6 and 2.6.7-rc2-mm2) hang there. Also note
the strange bogomips value for CPU 1. The system has three bricks
(6 CPUs, 1400MHz/3MB cache). Firmware is pretty recent (the newest
we could find at www.sgi.com):

002c06#0a: SGI SAL Version 3.25 rel040225 IP41 built 12:01:43 PM Feb 25, 2004

I have the following compiler (default in SLES 8):

$ gcc -v
Reading specs from /usr/lib/gcc-lib/ia64-suse-linux/3.2.2/specs
Configured with: ../configure --enable-threads=posix --prefix=/usr --with-local-prefix=/usr/local --infodir=/usr/share/info --mandir=/usr/share/man --libdir=/usr/lib --enable-languages=c,c++,f77,objc,java,ada --enable-libgcj --with-gxx-include-dir=/usr/include/g++ --with-slibdir=/lib --with-system-zlib --enable-shared --enable-__cxa_atexit ia64-suse-linux
Thread model: posix
gcc version 3.2.2

: But don't forget that you need to pass 'console=ttyS0' on your kernel boot 
: line (it's easiest to add this to your elilo.conf file).

	Yes, of course. I have the following in my elilo.conf:

prompt
timeout = 80
read-only
relocatable
 
image = /vmlinuz-2.6.6
    label = 2.6.6
    root = 900
    append = "console=ttyS0"
[...]

: Yep, linux-ia64@vger.kernel.org
: 
	OK.

: Stock (i.e. non-SGI or non-SuSE) 2.4 kernels won't work on Altix.  You need 
: 2.6.
: 
	OK. 2.6 was my primary target, I have tried 2.4 only because
2.6 failed to me.

: It should work fine.  And linux-ia64 is probably a better list (more chance of 
: me seeing your message).
: 
	Thanks, I will subscribe to it.
