I am trying to debug a boot hung and in the process I generated a vmss file (suspended the VM) and then converted to a vmss.core file using:
vmss2core-Linux64 -N file.vmss file.vmem
I also installed the debuginfo for my kernel version: 4.1.12-94.3.9.el6uek.x86_64
The issue I have is that when I run: crash /usr/lib/debug/lib/modules/4.1.12-94.3.9.el6uek.x86_64/vmlinux vmss.core I get the following error:
WARNING: kernels compiled by different gcc versions:
/usr/lib/debug/lib/modules/4.1.12-94.3.9.el6uek.x86_64/vmlinux: (unknown)
vmss.core kernel: 4.4.7
/usr/lib/debug/lib/modules/4.1.12-94.3.9.el6uek.x86_64/vmlinux is not SMP -- vmss.core is SMP
I am not sure what is that I am doing wrong (used to do this on CentOS and it did work).
I am running crash on the same system (uname: 4.1.12-94.3.9.el6uek.x86_64)
