SGI O2K installation problem

Jun 1, 2005, 2:33 AM

Post #1 of 7 (2470 views)

Hi everybody,

I have an O2K SGI machine and I'm trying to install linux on it.
I've crosscompiled 2.6.11 kernel and it bootp, but after
"freeing unused kernel memory"..
things stop working.

I put on a local disk the sgimips-initrd-20050530 image and the boot
parameters are: bootp(): root=/dev/sdb1 nosmp

I've searched the internet and I know my problem is due to init, but I haven't
found a solution. sgimips-initrd-20050530 is built to mount nfs root, but I
don't have a working ethernet connection (on boot eth0: link down). Should I
modify the linuxrc script? How?

Could you please help me?

Thanx,
A.

Short answer: recent kernels don't work on these machines. Just use our
2.6.6 netboot for ip27.

ok. I suppose it's the ip27-r10k+-20040528.img.
Downloaded, put on the bootp server.
boot parameters -> bootp(): root=/dev/sdb1

Maybe the problem now is the root file system because boot process hangs on:
kernel panic: attemped to kill init!

Sigh!

Do you have a working userland on /dev/sdb1 already? Also, that kernel
is known to more or less work with O200 systems, but I'm not sure it has
been tested with an O2K setup yet, so you may be in uncharted waters.
Note, I don't have an ip27 box at all, so I'm just speculating.

The ip27-r10k+-20040528 image is NFSRoot only. So you need to setup an NFSroot
setup in order to use it correctly. All newer images use embedded ramdisks.

IP27 is just our red-headed stepchild. Someone will eventually smack it, and
it'll start behaving with newer kernels.

Thankx everybody, but thing are getting more and more difficult.
I can't mount an NFS root because the ip27-r10k+-20040528 image sees my eth0
down (it is not true, the cable is connected and the link light is on). My
O2K as 5 eth interfaces: may this be a problem?

I'm going to disconnect the second ethernet card and leave only eth0.
Let's hope.....

But if: http://www.linux-mips.org/wiki/index.php/IP27_boot_messages
why shouldn't I?

At http://www.total-knowledge.com/progs/mips/kernels/
I've found a working kernel that mount my local root on /dev/sdb1.

Now a new world of problem is opened..... :))

Thankx everybody,
A.
