New installation runs on SGI O2

[Giuseppe Sacco <giuseppe@eppesuigoccas.homedns.org>]

Hi all,
today I did a few installation runs on this machine. First of all I
tried the new netboot-boot.img, but all of them are failing since
2008-02-23 to 2008-03-06.

I got a different problem, when using a working netboot-boot.img, i.e.,
my machine power off after 120 seconds since kernel start.

Looking at the kernel sources, I found that this is a normal behaviour
on ip32: when in panic, start a 120 second timer and then poweroff.

Using this command line
  bootp(): append="root=/dev/ram0 initcall_debug console=ttyS0,115200"

I found that ip32_reboot_setup is being called just after registering
the PCI controller:

Calling initcall 0xffffffff8049d2b8: mace_init+0x0/0x3e8()
MACE PCI rev 1
registering PCI controller with io_map_base unset
initcall 0xffffffff8049d2b8: mace_init+0x0/0x3e8() returned 0.
initcall 0xffffffff8049d2b8 ran for 3 msecs: mace_init+0x0/0x3e8()
Calling initcall 0xffffffff80478920: ip32_reboot_setup+0x0/0x1a0()
initcall 0xffffffff80478920: ip32_reboot_setup+0x0/0x1a0() returned 0.

So, this is when the panic action is setup, but then I cannot find
anything useful.

A log of two different boots, the former with initcall_debug, the latter
without, is available at

Thanks to all,
Giuseppe
