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

Subject: Re: How to specify kernel version when restart kdump
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-trigger
Cheers,

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.
