Hi,

Just did the latest udev update on a Netra T1 105. It is running a kernel:

Linux aux3 2.6.11-gentoo-r8-Production-1 #1 Tue Oct 4 11:16:24 MDT 2005 sparc64 sun4u TI UltraSparc IIi (Sabre) GNU/Linux

Very stable. I have more than just several 105's and a E220 all running the same kernel and most are production boxen, again, very stable.

This particular box I used as a sacrificial lamb (not production) and rebooted it after this update (Big toe in water testing <G>)...

In the boot sequence, I get the following error that has never been present prior.

Unimplemented SPARC system call 151. This occurs here in the boot sequence:

NET: Registered protocol family 2
IP: routing cache hash table of 4096 buckets, 32Kbytes
TCP established hash table entries: 16384 (order: 4, 131072 bytes)

process `named' is using obsolete setsockopt SO_BSDCOMPAT

Is this something of great concern? Since they have always booted so cleanly, it startled me.

Thanks in advance for any assistance in this issue.

That's a process calling an unimplemented system call (kernel function).
It can or can't be important, it depends.
Best suggestion is to upgrade to a more recent kernel, for sparc that's specially important since many fixes were implemented into 2.6.13/14/15.
gentoo-sources-2.6.15-r1 is keyworded ~sparc, i'm using it in a couple of machines without issues so far (u5, e420, v240).

Hi there,

Hummm... How long have you been running 15 on those machines? It took me a long time on a sacrificial lamb before finding a 2.6 I felt comfortable with <G> I hate changing for the sake of change, if you know what I mean... A lot of folks thought I was pretty guttsy even thinking about running a 2.6...

I've been following the 2.6 series lately and getting patches into gentoo-sources that fix stuff (like strace/ptrace).
The v240 isn't quite stable with anything actually, but it's working just fine with the 2.6.15 series.
The u5 has been running flawlessly on it.
The e420 i didn't hit as hard but had no issues so far.
In any case 2.6.15-gentoo-r1 or vanilla-sources-2.6.15.1 is >= what you're currently running.

Thanks a bunch.

I am compiling a 2.6.15 as we speak. I have the afternoon off so may not implement right away. Maybe over the weekend <G> It's on my test box, so no loss if something goes south, although I've been lucky and never had an issue changing kernels remotely <knock on wood>.

I will let you know if that undefined call goes away with the new kernel...

Have a great day & weekend. 8)

Well, it appears, so far, that it is up and running okay. I moved the new kernel into place on Saturday. It's a spare box, so it doesn't do much though...

Yes, the system call error has vanished.

My next box is my personal server. It's not a hammered box, but it's busy. We'll see if that 15 kernel will hold up there, then move it into place on some other boxes that are company owned <G>

Thanks for the help and have a good day! 8)
