Hi all.

I tried to install a Gentoo on a SGI Octane, and had some networks problems once the linux kernel has booted (the hardware itselfs works, as I can get the boot image from a tftp server).

After some searches, I found on forums here that this a known issue:
eth0 never gets "RUNNING", and never sends packets.

The temporary solution was to use an old kernel image, but I couldn't find one which boots correctly AND doesn't have the ethernet bug (including the latest I found, ip30-r10k+-20050820.img).

Is there a newer archive somewhere which may work ?

Or is there an HowTo somewhere to build such images from sources, which could be a base for me to start tracking down the bug ?

Thanks,

Yvan.

The image you mention is indeed the latest one. How does it not boot correctly?

It boots, but when I set up eth0, I can't join the network.

I'm *sure* that I set up correctly IP, netmask, gate, etc...

I'm sure that the cables are good, as I got the boot image via tftp.

And when I look at ifconfig eth0 output, I can notice two things:

- interface is "UP", but not "RUNNING"

- Tx counter stays to zero, even if I try to send pings (and a dump on the network shows nothing, not even a single ARP request).

Rx counter increases when I try to send pings from another host. Well, the station probably sees arp requests, not ICMP echo requests, but Rx counter increases only when I try to contact it.

Dmesg also shows that eth0 link is detected as "down", where it is in fact up.

I found this thread here describing exactly then same problem:
https://forums.gentoo.org/viewtopic-t-350773-highlight-octane.html

But the solution used (use an older image) doesn't work for me: image ip30-r10k+-20050530.img has the same problem, and image 200501(don't remember the exact day) freezes during boot.

Well, the fix to the bug in the 20050530 image, was indeed to use the later image (20050820). The issue was a bug with IOC3 which h0rked the ethernet driver, which the newer netboot image fixed (apparently).

Are you sure that's the image you're booting? Is there a chance the machine is picking up an older image by mistake?

The ethernet bug was a fun one. It was introduced in 2.6.12-rc4 as an update to the core ethernet code, and it actually exposed a dormant bug in the IOC3 driver. The 200508 netboot is fixed, so make sure your tftp server is sending the correct image. Alternatively, if you have an external CD-ROM, you can use the RC5 livecd, which I definitely know works.

I don't know what strange manipulation error I made, but you're right: there was a chance that I still used 20050530 8)

I just checked md5sum of tftpboot copy, noticed my mistake, copied the good image (20050820), booted again, and the network works.

Sorry, and thanks for the quick answer !

Yvan.
