Hey There,
Does anyone know if the latest crash is supposed to work with kernel
dumps produced by SLES 9 LKCD facilities? If yes, HOW? I was told it
should be working at one point, but with the latest crash (4.0-4.5) it
doesn't seem to work. Here is what I did:
1) With the map and kerntypes files created by lkcd along with the dump:
# /dumps/new/sles/native$ /home/dli/bin/crash map.0 kerntypes.0 dump.0
Then crash complains the kerntypes file is not SMP while dump is (see
below), even they were produced by lkcd at the same time and worked with
'lcrash' with no problem what-so-ever.
2) Then I built a debug vmlinux using kernel-source package on the same
host that produced the dump, and tried to feed it to crash:
# /dumps/new/sles/native$ /home/dli/bin/crash vmlinux dump.0
And crash complains the debug vmlinux file and the dump created by the
non-debug kernel do not match.
Here is output of 'uname -a' from the host:
tst037:/usr/src/linux-2.6.5-7.97 # uname -a
Linux tst037 2.6.5-7.97-smp #1 SMP Fri Jul 2 14:21:59 UTC 2004 x86_64
x86_64 x86_64 GNU/Linux
Any thoughts? (Outputs from crash with '-d 4' flag are attached below... )
Thanks,
Daniel
