Hi,
On 2.6.18-rc3-mm2 with hotfixes I get things like the appended one on attempts
to suspend to disk. It occurs while devices are being suspended and is fairly
reproducible.
Greetings,
Rafael

So even if we didn't deref a kfree'd pointer, we're about to.
It would be good if you could poke around in gdb, work out exactly which
statement it's oopsing at, please.

I'm also interested to know if the problem goes away when you disable

Maybe the skge driver is not doing netif_poll_disable before clearing the rx
ring at suspend/down?

Apparently it doesn't.
At least netif_poll_disable is not referenced anywhere in skge.c .

With the patch I can't reproduce the problem. I sometimes get the error
messages from the interrupt handler, but then it doesn't blow up in
skge_poll(), so I think the patch helps.
Thanks,
Rafael

That looks good, but needs a few more changes for full safety.
Kind of like the sky2 changes needed to get Mac Mini to work.
The machine I have with skge boards don't suspend right but that is because
of other problems.

0x44 is a REX prefix in 64-bit mode, so somehow ksymoops got it
wrong and gave you an i386-mode decode instead of 64-bit mode.
Did you run it on a i386 machine and it assumed i386? Maybe you
need to use "-a x86-64"? (I can't make it work on my setup.)
So it's really "mov (%r8),%ebp" if I am reading the manual right.

I don't know what ksymoops's problem is. I noticed that without `-a' it
gave x86 code so I gave it `-a i386:x86-64' and didn't bother to read the
output ;) Seems that nothing I can do will persuade it to not treat this as
i386 code.

Back in 2000 there were a lot of version problems between ksymoops and
libbfd and libiberty, so I statically link against these libraries when
I build the rpm. You have an i386 version of ksymoops, which was built
against an i386 only version of libbfd, it does not support target
elf64-x86-64. Grab the ksymoops src.rpm and rebuild on x86_64, or use
a binary rpm from an x86_64 distribution.

But would such a binary be able to decode i386 oopses?
ftp://ftp.kernel.org/pub/linux/utils/kernel/ksymoops/v2.4/ksymoops-2.4.11-1.src.rpm
fails to build, btw. Had to do s/Copyright/License/ in the spec file.

It depends on your versions of bfdutils and binutils. ksymoops does
not decode the object itself, it uses bfd and objdump to do the work.
FWIW, the version of ksymoops in suselinux 10.0 for x86_64 will handle
both i386 and x86_64.

Ah, the joys of changing RPM standards.
