[gentoo-mips] Problems with mips-sources-2.6.20

[gentoo-mips] Problems with mips-sources-2.6.20

[Mathias W.]

Hi,

I have running an Octane and an Octane2 with a kernel built from mips-sources-2.6.17.10
(2.6.17.10-mipsgit-20060618-ip30r10k+) right after installing the base-system at that time
and they are running fine (currently as LAMP-Servers).
Now I tried to update the kernel to 2.6.20.13-20070415.ip30 and mainly used my old .config (Just did make oldconfig) and
it doesn't boot. I get the same message as in this thread: http://archives.gentoo.org/gentoo-mips/msg_00503.xml

NESTED EXCEPTION #1 (vid 0) at EPC: ffffffff9fc6a0a4; first exception at PC: 0

Several weeks before I tried 2.6.20.6 (which wasn't marked stable) and couldn't get this to boot either.
The system is uptodate. Here is my toolchain:
 gcc-config -l
 [1] mips64-unknown-linux-gnu-3.4.6 *
 [2] mips64-unknown-linux-gnu-4.1.1
 [3] mips-unknown-linux-gnu-3.4.6 *
 [4] mips-unknown-linux-gnu-3.4.6-hardenednopiessp
 [5] mips-unknown-linux-gnu-4.1.1

Any new suggestions to solve this apparently known problem?

Have you tried to build your kernel with gcc-4.1.1 instead of 3.4.6?

Not yet, because this is the only system, where the kernel builds. On the other system(s) I still have problems like
this:  http://archives.gentoo.org/gentoo-mips/msg_00571.xml
I know that the bug http://bugs.gentoo.org/show_bug.cgi?id=171486 is fixed with the new binutils-config but I still
don't get a vmlinux on this system because of the same error as in comment 7 of this bug
(http://bugs.gentoo.org/show_bug.cgi?id=171486#c7). And this all happened after switching to gcc-4.1...

But I'll try to do it now and see if it will break.

Re-run binutils-config manually, as this will fix the ldscripts bug, and then 
source /etc/profile.  Binutils-config doesn't do this automatically, so it's 
caught a few people off guard.

Second, whenever you use an older config on a newer kernel, _always_ check the 
config to make sure it didn't flip something off.  Things changed dramatically 
from .17 to .20, and relying on oldconfig alone isn't recommended.  I usually 
run through menuconfig and just check the categories myself.

That all said, nested exceptions sometimes point at ARCS bugs.  You may have an 
out-of-date PROM.  Unfortunately, we're not sure which PROMs are out-of-date, 
and which ones aren't.

Any special parameters to do this?
I've already done this (as this was mentioned in bug 171486) and did it now again.
As I have only one version of binutils I just added the "--mips" parameter.
It finished without error.

I still get this error after compiling the kernel: http://bugs.gentoo.org/show_bug.cgi?id=171486#c7
...
  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      vmlinux
lib/lib.a: could not read symbols: Archive has no index; run ranlib to add one

I still have to check the NESTED EXCEPTION bug...

Now I carefully looked through menuconfig and did some additional customization but didn't find anything obvious wrong.
Still the new kernel does not boot.
I'm willing to try a config from you guys if you have one for the octane/octane2

I have "PROM Monitor SGI Version 6.5 Rev 4.8 IP30 Sep 6,2001 - 64 Bit"
