Re: [Crash-utility] crash tool not working
----- Original Message -----
And lastly, in all cases where a dumpfile cannot be read correctly,
first verify that crash works with the live system. Presuming
t, and it was configured CONFIG_STRICT_DEVMEM, try this:
Sorry -- cut-and-paste error -- I meant to state "Presuming that
the kernel was *NOT* configured with CONFIG_STRICT_DEVMEM".
# crash ../linux-2.6.32.12-0.7/vmlinux
If that comes up OK, then we can rule out more fundamental
failure causes.
If you did configure the kernel with CONFIG_STRICT_DEVMEM,
then you can try the supplied crash utility memory driver
as a replacement for /dev/mem:
# cd <path-to>/crash-6.0.3/memory_driver
# make
...
# insmod crash.ko
and then try running on the live system.
