Altix hang on boot with 2.6.8+

Altix hang on boot with 2.6.8+

[Jan Kasprzak]

	Hi all,

I cannot boot a 2.6.8 or 2.6.10 kernel on my SGI Altix - it hangs during
boot after printing this:

[...]
CPU 0: base freq=200.000MHz, ITC ratio=14/2, ITC freq=1400.000MHz+/--1ppm
Console: colour dummy device 80x25

(from the 2.4 boot messages it seems that tha BogoMips test should
be the next line). 2.6.6 boots fine. I have also tried CONFIG_EFI_PCDP
and console=hcdp. 

The system is 3-node (6-cpu) Altix 350 running SLES 8.
Can 2.6.8+ boot on Altix 350? I may test 2.6.7 or -rc* if you want.

Full boot messages are here:

The Altix console changed from ttyS0 to ttySG0 around 2.6.8.  You need to
  mknod ttySG0 c 204 40
and change elilo.conf to use console=ttySG0 for the newer kernels.  You
also need to change /etc/inittab from ttyS0 to ttySG0.

Most Altix systems running 2.6 have both ttyS0 and ttySG0 defined in
/dev and have two lines in /etc/inittab to allow switching between old
and new kernels.

OK, thanks. I have found that few minutes after sending my previous mail
- 2.6.8 booted even without console. I did not wait long enough, because
2.6.10 did not boot even after a long time - so there may be some other
problem with 2.6.10 or with our init scripts on 2.6.10.

:   mknod ttySG0 c 204 40

	Thanks again,
