i recently wanted to check something in my `dmesg` output.
but i saw something i didn't expect :)

i do not know how long it's been there, since i don't check it that
often, but... do i need to worry about something ?

FWIW; this was 2.4.19-pre5 on a sunblade100


this is what i got:

data_access_exception: SFSR[0000000000801009] SFAR[fffffd0000000028],

i would, if i could :)
so, i downloaded ksymoops-2.4.5 (i assume this is the version i need)

but it won't compile. sorry, my c knowledge is very basic.
but i assume there's something wrong with my /usr/lib/libbfd.a ?

ksymoops should be already installed on your system
at /usr/bin/ksymoops, if it isn't find the package
to install or complain to your distribution maintainer :-)

If you still want to compile ksymoops from source you need to update
and install a new binutils to get the latest BFD library.

allright, ksymoops doesn't come with my distribution (Splack)
so i got the source, and went from there.

now it compiled nicely.

here's the output that i get (i'm not quite sure what to expect, so i
hope this is what you need:)

I've seen the same when ksymoops was linked against old libbfd.
It builds without errors but could not disassemble oopsed code.
Check for old libbfd lying around.

sorry for the long lines, but it would't be very readable otherwise
:)

it all looks like the new version to me


ps: it's the first time i actually use ksymoops, so excuse my
newbie-like behaviour :)

Double check that you built ksymoops against these libs, not older ones.
Even if you deleted them, you may still be using old ksymoops binary!

i don't have an old ksymoops binary :) it just did not want to
compile until i removed the old binutils, and installed the new
version.

just to be sure, i removed the source dir for ksymoops, unpacked it
again, recompiled, and ran it from thre. same result.


i think i'll just let it rest, and give it another go next time i get
an oops :) so far my box seems to be running as i expect it to run,
so i won't worry too much about it.
unless one of the developers really needs it :)

best regards,
Jurgen.

Re: arch/sparc64/kernel/traps.c

[Luigi Genoni]

what version of binutils are you using?
please upgrade them (sources from ftp.kernel.org).

Hi, I had similar problem, took me months to figure it out.
I suggest:
* getting latest binutils, compiling and installing them
* thorougly checking that *old* binutils aren't interfering
  (in my case ksymoops got linked with old libbfd.a despite
  newer one was also installed! 8-[ )
* compiling ksymoops
