I want use kdump & kexec, so I installed kexec-tools, configured /etc/kdump.conf and kdump.service. STFW, according to the steps, I can use kexec -l, then kexec -e, change to the new kernel successfully. But when I use the kexec -p with the same parameter, trigger a panic, the new kernel didn’t work without “Starting crashdump kernel… Bye!”

Check out our Code of Conduct.
So the “panic” you showed above is not the failure (or success) of the crashkernel starting – it is all still the output of your ordinary host kernel (it’s “reaction” to the SysRq-C).
Your kernel messages show a 2nd pagefault (the Unable to handle kernel NULL pointer dereference at virtual address 00000038 – notice 0x38 not 0 as in the “triggered” one), not sure where, code-wise, this sits, and it’s conceivable this happens during the attempt to “handover” to the crashkernel. But at least the log / console messages you show do not have evidence of the crashkernel loading or booting. Without access to your specific hardware, it’s hard to “hint” what could be behind this. I’d troubleshoot somewhere along those lines:
- any other console messages following these ? Or is the console / system stuck at this point ?
- when “there”, does the system still react to
SysRq? If so, it’s an indication the crashkernel hasn’t booted; useSysRq(t,l,w, …) to extract more diags on what the system might (not) be doing then. - does it still react to NMI (many systems allow NMI to be triggered either by button or by mgmt controller; again, I do not know what kind of ARM system – developer baseboard, server machine, anything-in-between) you have. If so, what is shown ?
- you could try passing more-verbose/more-“chatty” command line options, and/or additional debug-only console devices, to the crashkernel using
kexec -p --append=...and see if that gives any more output. - likewise, make your host kernel’s console output as verbose (
echo 9 > /proc/sysrq-trigger) as possible before triggering the panic.
Also, try getting help through the kexec mailing list, http://lists.infradead.org/pipermail/kexec/ – it’s reasonably active.
