After the above output the machine got freezed. After waiting for
sometime, i have to hard reboot the machine. There is no crash log
generated.
I checked the CONFIG_STRICT_DEVMEM:
--------------------------------------
hltncra110731:/home/adil # zcat /proc/config.gz | grep
CONFIG_STRICT_DEVMEM
# CONFIG_STRICT_DEVMEM is not set
hltncra110731:/home/adil #
--------------------------------------
My running kernel is the one which i have build:
--------------------------------------
adil@hltncra110731:~> uname -a
Linux hltncra110731 2.6.32.12-crash-crash #66 SMP Thu Feb 9 19:58:42
IST 2012 x86_64 x86_64 x86_64 GNU/Linux
adil@hltncra110731:~>
--------------------------------------
Your system is running a kernel with a utsname version "2.6.32.12-crash-crash",
but you used a file named "linux-2.6.32.12-0.7/vmlinux"? Are they exactly
the same kernel?
Also, even though you're back to using crash-5.0.1 again, I afraid I can't even
speculate as to what would cause the machine to freeze, nor have I ever seen
such a thing happen before. Perhaps the /dev/mem driver read something it
should not have based upon a faulty virtual address? I don't know...
Does this problem something related to hardware / bios configuration?
I am providing the details, if by any chance it helps you:
Sorry no, that doesn't help. If you can't even get crash running
on a live system, then I'm running out of suggestions.
