Details

Description:
Using crash to debug a linux 4.0 kernel will lead to the following error

WARNING: kernels compiled by different gcc versions:
vmlinux: (unknown)
vmcore.dump kernel: 4.9.2

WARNING: kernel version inconsistency between vmlinux and dumpfile

crash: incompatible arguments: vmlinux is not SMP -- vmcore.dump is SMP

Additional info:
* Upstream has released a patch for this issue (see http://people.redhat.com/anderson/crash.changelog.html)
* I extracted the patches from the rpm source package (located here: http://koji.fedoraproject.org/koji/buildinfo?buildID=617219) and modified the PKGBUILD to add them (see attachment).

Steps to reproduce:
1) Build a linux 4.0 kernel with debugging symbols (vmlinux)
2) Create a core dump (vmcore) for that kernel
3) run the commmand 'crash vmlinux vmcore'
(application/x-gzip)    crash-7.1.0-2.src.tar.gz (2 KiB)
