What do you mean? Wouldn't the kernel version always be the actual running version of the kernel that was booted?

kdump operates by booting a fresh kernel to capture the context of a crashed kernel, and so the only way for kdump to dump a kernel is to crash it and cause kdump to invoke its post-crash kernel.
You can manually force a running kernel to panic (and invoke a correctly-configured kdump) with the following command sequence:
echo 1 > /proc/sys/kernel/sysrq echo c > /proc/sysrq-triggerCheers, Ben
Hi, Ben
I think your response doesn't answered my question. I'm not asking how to trigger kernel crash and see whether the kdump is works, but asking how to specifying kernel version when start kdump service.
Thanks.
