We do not have persistent memory to connect to pstore. We have ramoops and kexec/kdump enabled, and I can see that the call trace output from a SysRq-C (along with other dmesg content) is in vmcore (via hexdump), but am struggling with how to extract that from /proc/vmcore (hopefully quickly so that kexec/kdump can finish and restart the system to full functionality). 

Any help/guidance would be greatly appreciated.

Thank you!
